I build bat houses for the Panhandle Pioneer Settlement in Blountstown Florida. One of the things that we also learned based on years of experience is that. Don’t use stains or oil based paints. Only use water based they do not like the chemicals. Also when first starting a bat house smear on bat guano or poo onto the screens to draw them in. Works great for us since we have over 200 bats in two of our bat houses.

[@StateFarmAFO]

Are your bat houses available for purchase? Thanks

[@boonedog1457]

3 years in a row now, bats have made residence on our cabin, behind window shudders, facing south east. We love having these guests. The other day we purchased a "Bat House" and will be installing it on the south east corner of our house. I am relocating our American Flag to do so. LOL...Our bats are getting priority positioning! Our flag will be relocated away from our bats. They are going to love their new home! We have a vegetable garden, flower gardens, and lots of mosquitos, gnats, etc. We have a perfect habitat for our little fury bat friends. Thank you for your helpful tips. Your video is most excellent. Thank you "Bat Man!"

[@boonedog1457]

@Colton, We did buy the bat house, but getting a pole to install it on has become a real challenge. We don't have the right vehicle to haul it and we live in the country and no one will delivering. So, needless to say, our bats are still residing (in the summer) behind our shudders. They are content there, but we really want to introduce them to our bat house. We will figure it out. Meanwhile, we've noticed our flying insect population has diminished, which is great. We want more bats!

1. Bats like 85-100F 2. Direct sunlight 3. Early warming (facing East) 4. at min10ft from ground 5. clear spaces 6. free of mud-dobbers & wasps 7. water at min 1/2 mile from bat house

[@h4bats]

Install a quality bat house, put it in a good location as described and wait. That's about all you can do. Sometimes you get bachelor colonies which will move around all year, come and go, stay a day/week/month and move on. They are less picky on exact conditions. If it is a really good location, you may get a maternal colony (which is what most people think of when they think of bats in a bat house). A maternal colony is the group that has the most specific needs and what the guidelines are based on. Thanks for loving bats!

What about keep them warm during the winter months or do they leave and come back? Sorry just started thinking about doing this to help with my mosquito problem, and I am completely ignorant on the subject.

[@h4bats]

Bats will typically leave during the winter and go hibernate or head south depending on the species and their location.

[@jaystern5936]

I have a house at Big Bear Lake, CA. In the summer (July - September), we have a colony of Little Brown Bats that calls our house their home. They roost under the roofing and exit along the edge. I would like to install a bat house for them in hopes of allowing the colony to grow. I haven't done it because I understood that the temperature wouldn't be high enough. During the day, the roofing temperature really is high. Of course, in the winter it snows and by then, they have all migrated south. So my question is, if I build a bat house, should I apply some fiberglass insulation to help make the temperature more consistent?

[@dryakichful]

Thanks for the video! I found a product called uncle dunkles bat attractant. Would you recommend that to attract them to the newly built bat house?

[@h4bats]

There is no known way to attract bats. I have asked dozens of bat biologists that exact question, all of them agree, no research supports any method of attracting bats. All of the stories are anecdotal "I spread bat guano and the next day, there were bats there!" We don't know the bats would not have shown up anyway. And they do show up all the time without bat guano, and bats are territorial, you could be telling them to stay away. What is known, bats can live up to 40 years in the wild, they learn by experience and remember. They are also curious, so they will be looking at their environment, what's in it and remembering where they can take shelter.

[@levicrane6101]

I live in south Mississippi. I have had this idea to build a large scale bat house to collect and sell the guano or at the very least use it in the garden. Do you have any tips for a large scale bat operation?

[@hudsonhousejournal7063]

After building the perfect one chamber bat house with cedar and plastic mesh and stainless steel screws, my large bat population refuses to leave the hollow tree that has been home for the past 20 years. The bat house is perfectly positioned 15 feet in the air on a pole in a mostly sunny location. But the rotted tree is over 65 feet tall and needs to come down. I am hoping to find a away to make the tree less attractive to the two dozen bats that live there. They don't seem to mind the endless parade of squirrels and birds constantly going through the hollow trunk and branches. We even have a returning hawk that nests every year about 300 feet away. In the summer the bats come out and fly around the neighborhood every night.

Bats will eat mosquitoes but do not intentionally target them. Think of bats as helping reduce bug populations all around, not as mosquito control. More bats means less bugs including mosquitoes.

[@h4bats]

I don't know what species you have there, or which your little friend may be, but if he has found a place he keep returning to, he's happy there. Also, not all species roost in colonies (i.e. not all with use bat houses) some species are solitary or live in small groups. In Costa Rica, you're going to have bats active year round.

[@kathybaca]

We did all of that. Thanks. We had a swimming pool that was a pond next door. Squitas everywhere. House was on a lone pine and up high. ( Long Island ) Sandy took down the trees and trying again next summer on a high pole. Pool was cleaned up with new owners. Hoping.

[@h4bats]

kathybaca Hang in there, bats are picky critters. Sometimes they only use a roost occasionally and go unnoticed, it's still important for the roost to exist. In the NJ area we lost a lot of bat roosts and many of the bat houses we shipped were lost. We had many new and reorders from the area in the months following but it can take years for bats to fully return to an area. We also have no way of knowing how many bats were lost in that event, if a roost with bats in it was destroyed and blown to the ground and flooded it's unlikely many (if any) of that bats in that roost survived. Bats that were able to remain in their roosts that may have been stabilized and above the water line would fair much better by may have gotten out of town at the next opportunity. We'll have to wait and see how things recover, but I'm sure they will.

[@jameshambrick7918]

Can I put my bat house on a light post at the end of my driveway? It faces south and is sunny. Will the light keep them away? Thanks!

[@h4bats]

The light is not likely to bother the bats in the least, they are out having a good time at night and eating all the bugs it attracts. Just make sure you own the pole you mount the bat house own and its location will not interfere with access to the light for maintenance. Power companies tend to discourage people hanging stuff on their poles.

[@WontSeeReplies]

I’m wondering while in colder climates, if it would be worth sacrificing a little sunlight for a wind block? In Wisconsin for example, I can hang the house in direct 360 degree sunlight. But it’s also completely exposed to the elements. Where if I built it into the southeast side of my house, it would have a wind block and thermal consistency. Any thoughts? And how do they survive subzero winters?

[@h4bats]

Bats will typically not remain in a summer roost during the winter. Morning sun and at least sun until a little after noon would be the "normal" goal, but bats are creatures that make up their own mind. If somewhere is always windy, certainly some wind cover would be appreciated in a roost provided the temps remain comfortable for them (85 to 100 degrees F). i.e. I doubt they would trade a solid warm roost in the wind for a shielded 60 degree roost, it wouldn't make sense to them as they would have to burn fat to stay warm. Thanks for loving bats!

Dear Batman, what about if we're putting this on the 25ft point of our garage roof and there is a light about 10 feet below the point. It is on all night for the backyard and I'm wondering if this will keep bats from using the bat house. We have plenty of mosquitos and fly's on our garage door during the night for them to feed on. It is the ideal placement for sunlight during the day and open area for them to go in and out from the bat house. Thanks for your videos, The Joker

I would like to install a bat house or two on my property but have a huge woodpecker problem. Are there bat houses made out of a non-wood material that work?

[@h4bats]

Composite bat houses, in my experience, have been less successful. We designed and built a bat house made of full composites, PVC and a few other materials including trying a bat house that was roto-molded from a plastic like materials. They all failed temperature tests in direct sunlight. Unlike wood they transferred and held the heat too well, I was getting 140 degree temps inside while properly painted wood bat house was showing about 95 to 100 degree inside. If you do use one, make sure it has more shade and be careful with any direct sunlight. Wood peckers can be a problem during mating season. We have found not having anything for them to perch on greatly reduces the attack on bat houses. That's why we no longer include the "deco bat" on the front of our bat houses, it created a perch for woodpeckers. Another tactic we have used is to place a piece of aluminum flashing over the area(s) the wood peckers seem to like and paint them to match the bat house. Thanks for loving bats!

[@mrstn123]

I live in Arkansas. Our summers are pretty hot. Up to 97 and a few 100 days.I put my bat house out in the full sun . Should I move it?

[@h4bats]

Full sun is fine, with the heat you have the option of getting some shade. Otherwise, you use a lighter color of paint to cool the house down. Don't use black, probably a medium brown to slightly lighter tan. Bats prefer the temps between 85 and 100 degrees.

[@oh1stnflight221]

Thoughts on why after many years of having bats (90+) in my bat house, I no longer see them in there in the last few weeks when I check during the day. We're still having very warm/hot weather here in Ohio so I don't think they've migrated away.

[@DoctorBlankenstein]

Just got my first bat house, and man am I excited to set it up for the little ones. I heard some Long Island bats passing through my backyard last night, and I don't even have the house set up yet! With this, may hopes of actually getting some to live in their new home have been seriously boosted. Habitat For Bats (aka Batman): Am I wrong for thinking this? If I am already hearing bats in my yard, and I do the right thing with their home... I should be looking at bats quicker than others?

[@h4bats]

You are providing a roosting opportunity for the bats. Put it up in a good location and wait for them to move in. How fast will depend on many factors including on the predominant species in your specific area. If you have a large population of red bats they tend to use trees, not bat houses. But that does not mean other species are not around too. Keep a bat watch for those bats!

I'm worried that full sun might be way too hot here in Florida, but I don't know. I'd hate to make a bat oven. Input?

[@h4bats]

Use a larger bat house, 3 or 4 chamber, they provide more areas inside to move around during the heat. Make sure it has vents on it and paint it a lighter color. Think of two identical cars, one black, one white. Both parked in the same parking lot on the same day with have vastly different temperatures inside simply due to the lighter color. In FL, I see a lot of pinks, light blues etc.... Good luck and thanks for loving bats!

[@charlotteskeeters3460]

I live in Oregon, it is October. Wonder if I should build & mount my bat house now in the Fall or wait until Spring. Where do bats go in the winter?

[@h4bats]

+Charlotte Skeeters The absolute best time to put up a bat house is when you can and will, any time of the year, even in the winter. Bats that use bat houses head south or find places to hibernate, typically in large colonies, for the winter so they won't be around. But, some theories hold that a bat house that has been installed and weathered a few months will be more appealing to bats than a bat house that was just installed a couple of days ago. This gives the bat house more time to smell natural than artificial and it will be there waiting for the bats when they return to the area. So, don't fret about when the best time is for the bats, find a good time for you and if that means you have more time to install one this Fall than you will in the Spring, go for it!

[@cglarsen26]

Thank you. You cleared up many of my questions before I build a couple houses to place in my garage. I've seen bats sheltering in the gable vent so I was just going to place them right below that location about 14 ft high and paint the same color. If done properly, will they prefer the bat houses to the garage vents? It faces SSE.

[@cglarsen26]

Meant to say place 'on' my garage.

[@h4bats]

You will likely have to "sour" their current roosting location to get them to favor the bat house. The best way to do that is install the new bat house, then wait for them to leave for the winter and either add a screen over the vent or stuff a material like "Cobra Vent" made by GAF into the crevices so air can flow but the space is filled up. Another approach is to exclude them by putting something like netting over the vent and let it hang down, they can leave but then not return to the vent to roost. Good luck, let us know how it goes.

[@TheOrcasRule]

I know mounting in a tree is not ideal, but I keep all the branches trimmed around it do you think it could work? I can face it South/southeast, and no branches above to shade it. It's really my only option for mounting, and I already made a few houses!

[@h4bats]

While trees are not the best place, I have seen bat houses successful in trees. It will depend how easily predators can get to it and if it is getting enough warmth. Sounds like your might!

[@TheOrcasRule]

[@nicsalamin]

I have dozens of bats roosting inside my gambrel roof barn, if I place several bat houses on the outside of the barn, will they relocate ? The bat droppings have become quite a nuisance....

[@h4bats]

You can place bat houses, always the best first step. However, it is unlikely the bats will just move on their own. They will go out to feed at night and if you can find where they are leaving and place a net over it so they can crawl down to leave, the won't be able to get back in. If it is very confined, you could even tape papertowel or toilet paper cores over the hole so they can crawl out but not come back. If they are in the open and you are certain there are no pups involved, it should be fine. If there is any doubt that pups may be present, you need to wait until after about mid-August to exclude them to make sure the pups and fly and leave as well.

[@daveweber9737]

What about folks who live in hot areas like PHX Arizona? We have native bats here but temps here can routinely exceed 100 degrees for days. Any suggestions on where to place a box on my house?

[@h4bats]

Same basic rules for placement, facing S to SE, get morning sun. You can get shade sooner during the day (hotter climate) and you would want to consider a lighter shade of paint for your bat house. Depending on where you are exactly, you might go with a very light tan or even white if the bat house gets sun all the time. You also want a bat house with vents on it, not one with a solid face.

I was given a bat house and after reading your post I need to move it. One question. I remember when I was a kid living in Tucson I used to go out to the street lights and throw pebbles up in the air and watch the bats dive for them thinking they were bugs. I have an outdoor electric pole with a street light that comes on at dusk. What about attaching it to that. I'ts too high to attach the house above the light. Would the light coming on at dusk deter bats from moving in?South Haven,Mich.

[@h4bats]

The lights will not bother that bats, they will feed on the bugs they attract. However, you should never hang a bat house on a pole you do not own (assuming this is a power company pole) or a pole that may require workers to climb it for maintenance purposes (power or telecommunication poles). Thanks for loving bats!

[@shawnlacue8071]

Would you think foot traffic would bother the bats? We have a pavillion down at our pond and I was thinking that would be a good spot. High enough, gets a lot of sun. Just curious if the bats would be bothered by us being under them when we're there?

[@h4bats]

Not likely to bother them. It is more likely their bat poop will bother you depending on where they are hanging out. Never hang a bat house directly over where kids may be playing, people may gather (like a patio table), windows, doors etc... It's best to put them over ground or plants where the guano can fall, mix into the ground, wash away when it rains and the sun can dry it. Thanks for loving bats!

[@UndefinedBailiwick]

How do I attract a specific species of bat, though? I want Phyllostomidae bats so they can pollinate my cacti and other subtropical plants that flower during the night time. I'm in Las Vegas, NV and I know there's various species of bats here (they fly over the Luxor at night). The best one would probably be the California Leaf-nosed Bat, although I don't know if they would serve the same pollinization function as their close relatives from Central (southern part) and South America. Also, I already have Hawk Moths which pollinate during the nighttime, will the bats eliminate them from my yard? And would that overall be more or less beneficial for pollination? Can I put some bat houses out in the desert near caves and see if I can capture some?

[@h4bats]

Bat houses are for colony roosting species. There is no known way to intentionally attract bats except have a suitable environment for them and food. For nectar feeding bats, I have watched them use hummingbird feeders, you might try that.

[@ChurchClown7]

Thanks for these tips.

[@scotthenderson4376]

I am building a house with my grandson its 16"x 20" x 4.5" with a 5" landing area also screened. We are making a 1/2 divider for the inside and putting screen on all sections of divider and front and back panels also closing in the entrance to about 1" openings. Hopefully this will work good. my question is do you think I should add a pup catch section made of screen or will it do more harm then good it will be 15-20' up a tree facing south.

[@h4bats]

First, make sure you secure the screen VERY VERY VERY well. We get calls too often where people remove a bat house for maintenance and they find dead bats tangled in the mesh on the inside where either the stables were insufficient or rusted away allowing it come loose and tangle bats. We only used cut grooves for a roosting surface, but you can do it yourself by scaring the wood with a chisel or the end of a hand saw or using a router with a 1/8" bit to make cut marks. It does not have to be pretty or uniform, just scar up the inside to give the bats plenty of foot hold. They also don't have to be deep, 1/16" is plenty, they have very small claws and can cling well. As for the baby bat net... that will fill with guano if the holes are too small and could tangle the bats if too large and partially block the exit for the mature bats. Most bat species need to drop and fall a few feet before they can take flight, a net would block their ability to do that and force them to walk on the net out to the edge and try again. More time in the open moving about mean more exposure to hawk and other predators as well. They've survived without nets up to now, they'll do fine.

[@jesseelisabeatty3259]

LMFAO I found an old wood letter holder wondering if I can modify it into a bat house? Like put in small dowl sticks, to hold on to, and make the Chambers tighter..? Hang it upside down hang it up high . Do you think that might work.? I live in Daytona Beach FL.

[@h4bats]

It could certainly work if the material will stand up to the weather. I'm not sure how the bats would react, they typically like at least 20" or so of height in the chamber, but I've seen them roosting in much smaller houses before too. Seems the warmer the zone the more flexible they are on housing too as they don't have to rely on the structure to keep them warmer when it's colder outside.

[@tractorp2255]

im from georgia as well. Which color do you find works well down here. The house will be in full sun most of the day. It seems black would get way to hot.

[@h4bats]

We generally use a medium brown but for further South we sometimes go with a light brown. One good practice is to put up multiple bat houses each a different shade of color. Bats will actually move from house to house depending on their temperature inside.

[@tractorp2255]

thanks for the info. Ive always had an admiration for these creatures. It seems their numbers have been on the decline in my area lately though. They used to occupy a couple of abandoned buildings on our farm but i havent seen them in the past 2-3 years. Hopefully these houses will get them back in the area. Thanks for what you do and love your channel.

[@jeremyb5740]

We have had our bat box up for 3 years...we recently have seen 1 bat inside our bat box....it's a brown bat. Will more come or is this just maybe an anomaly? Will this one bat attract more???

[@h4bats]

It is possible more bats will show up. Or, this could be a bachelor bat just hanging out on his way through. Bats can live to be up to 40 years old the in the wild, they are one of the longest lived mammals for their size and they learn through experience and remember things that help them survive. They will also "bring friends" when they have found a good roost. There are maternal colonies (which is the kind of colony we tend to think of ) which contain females that give birth to a pup each year. That colony will typically roost int he same place year after year and give birth. They can reach large number, but males and non-reproducing pups will not be welcome in that colony. Then there are what we call bachelor colonies. These can be much smaller and will contain males and young pups. Those will move around more, they could be in one place one day and another place on another day. But both are important an need safe roosting space. I hope your bat friend will bring more friends and you will have a happy colony on your hands. Thanks for loving bats!

[@kcb3rd]

If the bat house gets too hot, regardless of color, can some very small vents be added to the side? Of course, make sure it is small and weather / water proof.

[@h4bats]

Our larger bat houses have side vents. You can certainly add more if needed/wanted. Our kits do not have side vents, the front vents tend to be enough for the 1,2,3 chamber kits. We are working on a 4 chamber kit that will have side vents.

[@chromasux2]

I put up a pine bat house last summer right next to our garden over a wide open yard. 1/10 mile from a creek and a pond, faces the right way. Yet only thing that's hung out up there is a sparrow that's built a nest three times. Hopefully one of these days I'll get the right things up there. I've seen them fly around.

[@h4bats]

Make sure you paint it, depending on where you are it may need to be darker to absorb enough heat for the bats to be comfortable. Bats prefer the temps between 85 and 100 degrees. Also, the size of the bat house should be at least 14 or so inches wide inside and 20+ inches tall to keep the interest of colony roosting species. The chambers (crevices) should be about 3/4" to 1" to work best for the bats. You can see our kits and finished bat houses at estore.habitatforbats.org Good luck and thanks for loving bats!

[@h4bats]

We found a colony of bats roosting in a bridge on I-75 north of Atlanta GA. They didn't seem to mind the noise at all, though I was looking for some ear plugs myself.

How do you get the temp right in the winter? I live in Los Angeles so I'm sure summer will be ok but winter will be too cold for them. What would you suggest?

[@h4bats]

No need to worry about the winter, when it gets too cold bats will either migrate to warmer climates or to a place to hibernate for the winter.

[@jonasschommer1671]

do I have to use cedar for bat houses? Here in Wisconsin cedar is very expensive. I would like to build them from pine. Does it really matter as I paint them black anyway.

[@h4bats]

Cedar is not required, in fact the oils from cedar could irritate the bats. It is a durable wood and properly dried and cured it is a good building material but not required. Besides, to get the heat in the bat house correct you'll need to paint it anyway. I do prefer to avoid plastics as they can get far too hot in dark colors nor do I know what some plastics might be off gassing as well. We use ACX exterior grade plywood, you can also use BC or even CDX. We prefer the higher grades for easy of work and quality. Make sure you do NOT get "Exposure 1" ply, that is not exterior grade and the glue will eventually fail if left exposed and de-laminate.

[@batsrule]

thanks

[@LymanDuggan]

I have heard that if you put Bat droppings inside, it will help attract them. U of F might mail you some. KZbin UF Bat House and Bat Barn. Good luck with your fine project. I would like to see more of them. I have too many big oak trees on my property to erect one high enough to attract them, I think.

[@SurvivingasMom]

Thank you for this. I would love bats in my yard! I'm definitely buying a bat house.

[@hrcnick11]

Ok here is a tough question, can I put up a Purple Martin house and put a bat house under it on the same pole? Would they share the same pole?

[@h4bats]

Only if the pole is sturdy enough, other than that I see no issues as the bats and birds are active at different times of the day. Thanks for loving bats!

[@kevinwoolever2680]

I live in upstate New York and was wondering two things . 1) our winters and bats and 2) will bats bother my honey bees.

[@h4bats]

Bats live in New York and when it gets cold, they move on an hibernate. It was actually the caves in New York where hibernating bats were first exposed to White Nose Syndrome back around 2006, but that is a different story. Bat will not bother honey bees, they are out at different times and bats don't like getting stung any more than we do.

[@andyalford7487]

I live close to the coast in Georgia, in Mcintosh County. Kinda flat down here, how likely am I to get a bat colony started down here?

[@h4bats]

Bats are everywhere including the coastal regions. If you look at one of our largest projects that was in Virginia, that was off the coast. We hope to get permission one day to go back and video the bat houses, we understand there are bats in them now.

[@tedyoung9825]

I'm wanting to put up a bat house and the only good location I have is on a light pole in the open area. Will this work being that the light is on all night?

[@h4bats]

So long as you own the pole you should be good to go. Power companies are bit picky when it comes to accessories on their poles. As for the light, the bats are active at night and will gladly eat all the bugs the light attracts, so, you might help make them fat. Thanks for loving bats!

[@catwilk8213]

With the bat decline in Ontario wouldn't it be a good idea to put bat houses on hydro pools where does possible or does that mess up their echolocation or something

[@h4bats]

I'm not familiar with "hydro pools". All I could find online was hot tubs. Bats are highly tolerant of their environment even when noisy and busy. We have a massive roost right here in a bridge on I-75 that has hundreds of thousands of cars and trucks daily going by. The bats literally roost inches away from tires going over their heads 24/7 and that colony is thriving.

[@rhythmfield]

I have a new bat house in early September - Is this a good time to put it up to be potentially populated next spring or can you just put them up anytime of the year? When do they most likely hunt for a new home location?

[@h4bats]

Pretty much any time of the year is a good time to put up a bat house. But, by having it up in September it gives new pups time to find it and remember where they can find a good roost. When they return the next year, they will not necessarily be welcomed back to the maternal colony for various reasons and have to seek a new home. Thanks for loving bats!

[@mdiggie5046]

zes you have shown us how to build a bat house but what is the the cutting list or plans

[@dadsvintagegarage7542]

I was thrilled with the effect and it was not intended, a happy accident!

[@rosemaria5387]

I live in Central Florida, do I need to paint my Audubon cedar bat house or is it light enough to keep it from getting too hot in the summer?

[@h4bats]

It is possible that it would benefit from paint in 2 ways, weatherproofing and the shade of the color will help control the internal temperature. Without seeing it, I would suggest during the heat of the day you take some internal temperature readings from the middle of the bat houses body (this can be done several ways, but most simply with a thermometer taped to a 10' stick of pvc pipe). Check it over several days and make sure the temp is staying between 85 and 100 degrees when it is sunny and hot. Think of a white car vs. a black car on a sunny warm day, if it is 85 degrees outside, the white car should be not much more than 90 degrees, but the black car could be 140+ degrees sitting next to it. If you find the bat house too hot, paint it a lighter shade of color. Hope that helps, thanks for loving bats!

[@rosemaria5387]

Thank you, I haven't put it up yet so I can easily do the temperature test..

[@catherinelejeal2847]

What happens to the bats during our summer days with 100 degrees temps in Portland Oregon if I paint my bat house black and the temp gets way to high a few days or weeks every summer?

[@h4bats]

You area probably calls for a dark brown, probably not black. Even so, the bat house should have vents about 1/3 of the way up and that area will remain at a lower temperature than the upper part of the bat house. If the upper parts gets too hot, bats will move down toward ventilation. When temps get unusually hot, it can be a challenge for the bats (just like it can be a challenge for everyone else) but they will typically find a way to cope, even leaving the bat house and hanging in the shade on sides of buildings during temps extremely high. I've even seen bats abandon normal roosts and head into sewers and culverts when temps hit 110 degrees. All we can do it our best and let the bats try to take care of themselves. Thanks for loving bats!

[@jim4805]

Why have I seen so many large colonies of bats in caves and old mines around here? The temps in these places are in the 50s or 60s. Do bats that roost in areas like that not use bat houses? Thanks.

[@h4bats]

Jim H Bats roost in caves and old mines in large colonies. While the cave temperature is low, if you get the temperature of the cave ceiling where the bats are roosting you'll find it's much higher where the bats cluster together. Bats will roost in what is available, if no caves are around they need to find a suitable structure. Most colonies will winter in large groups in caves over the winter, then they will venture out during the summer using buildings, bat houses, bridges etc... whatever they can find.

[@rvalderas1]

If they like it hot, what do they do in the winter? Go South? Do they vacate the house?

[@mmaides]

They are in a state or torpor which is like hibernation. It is very important not to disturb their house at that time. If they wake from it and there isn't any food they will starve to death.

[@shawnsmith4058]

Would planting plants and flowers attract them ?

[@h4bats]

Not so much attract bats, but attract bugs and moths which the bats will be seeking. Thanks for loving bats!

[@Richard-ov6vt]

I’m having about 20 or so removed from my attic vent. I’m getting a bat house bc I definitely like having them around. I just hope they find the house I’m buying for them!

[@h4bats]

Place it according to the guidelines and wait. You can check out our website, eStore.HabitatForBats.org to find more information.

[@stokmj]

i have a few acres next to a slew/lake that has, on some days, so many mosquitoes there is a high pitched hum in the air. so perfect place with lots of food for a bat. the question i have related to this video is..... the property has at least one great horned owl sometimes 2. what are the chances a bat house will be successful. any tips for me? thanks so much for your time!! its greatly appreciated!! :)

[@h4bats]

stokmj Placing the bat house in an open location, morning sun, away from tree limbs by at least 20 feet is a good start. No doubt the owl will prey on the bats in the area but it is already doing that. A good roost can give the bats a secure location to roost that the owl can't get into to get at pups etc... If you find an owl or hawk roosting on top of the bat house you can add some 2" or so screws to the top sticking up with something like electric fence wire to disrupt the landing area for them.

[@wolfgangreichl3361]

I have a bat cave in the hill right behind my house; is it even worth trying to compete with this establishment? What accommodations could I provide that they won't find in the cave?

[@h4bats]

There is always room for more roosts. Depending on the cave's size and how the bats are using it, the males and non-reproducing pups can need a "bachelor pad" to hang out in because females with pups will not allow them in their roost.

[@wolfgangreichl3361]

[@bradleytenderholt5135]

does the poison the Mosquito Abatement company spray affect the bats? if so how. also if they eat a dead moth that's been poisoned will it affect the bat?

[@h4bats]

Unfortunately yes, poisons sprayed to control insects is one of the impacts on bat health and bat population. Fortunately, newer formulations are less harmful than in the past. The impact on the bats will depend on the type of insecticide used.

hi, are they around LA becuase i think that they will not find their way near a beach do you think they would come to the house????? its been in a good position but no bats...

[@h4bats]

There are bats in the LA area. If a bat house has been in a location for 3 years or more you may want to move it after examining the location if possible. Look at it closely first as you may have some residents you are not aware of using it in small numbers and randomly. Bats do not always return to the same roost night after night or use the same roost all summer or even roost in large colonies. The male bats specifically will often roost wherever they can find shelter for the evening and then move somewhere else the next evening. I've seen bat houses reported to be unused actually turn out to be used upon closer examination. One indication would be very small black spots on the pole/structure where the bat house is mounted. That's sign of guano and if you only have a couple of bats using it randomly, it would be very easy to miss.

[@kwlweapons]

Is there a practical way to collect/harvest the guano from a bat house up in a pole?

[@h4bats]

Only if it is an impressively large colony. Just let it pile up at the base of the pole. Otherwise, there is generally not enough accumulation to ward off the effects of the sun, wind, rain that soaks it into the ground or erodes it away.

[@MagusMarquillin]

Couldn't you set down a square bin directly under the bat house?

[@Tonygarry78]

What's a good measurement for a bat house? Say, buying some ceader fence pockets? I wanted to make it myself

[@h4bats]

About 15" wide and chambers should be 20" tall or more. Bigger is typically better (to a point) as it will have better heat characteristics.

[@Green3062]

Can you use Boiled Linseed Oil for the interior of a bat house?

[@h4bats]

I would not for 3 reasons, first, "Boiled Linseed Oil" for wood finishes often has additives in it, it is not pure flax seed oil. Those additives can be harmful. Second, even if you use pure oil, it smells and could irritate the bats. Lastly, Boiled Linseed Oil takes a long time to try and is exothermic, meaning it can burst into flames as it dries. Give this bat house will be placed in directly sunlight, probably best not to use that oil.

[@christykrop3005]

What are your thoughts on hanging bat boxes under guard lights

[@h4bats]

So long as the guards don't mind, go for it! Actually, just make sure you own the pole. Bats are home and sleep during the day, there is no conclusive evidence one way or another that lights attract/repel/disturb or otherwise interfere with bats. The bats do love to eat the bugs attracted to the light though.

[@samanthakanagy4248]

I have two old window screens. Could I cut these to the appropriate size and use these as my mesh for a bat house?

[@h4bats]

We do not recommend meshes or screens. We prefer cut grooves or rough surfaces.

[@TwinMountain]

If temperature is such an issue why hasn't someone designed a solar heated bat house?

[@h4bats]

well... that's exactly what you are doing by putting the bat house in a proper location, heating it with solar power. The color of the bat house is important as well. The farther north the darker the shade of paint. Our cold weather bat houses are only painted black. On the coast, a light color is fine as the bat house needs to reflect more energy to keep it from over heating.

[@TwinMountain]

Do bats winter in the bat houses?

[@h4bats]

Carl Favorito Not normally. Usually they will either go further south in the winter or go to a cave or other roosting location where they hibernate in large colonies. The habit of hibernating in large groups is what makes them so susceptible to White Nose Syndrome.

[@TwinMountain]

Which, they say at Howe Cave, first appeared there.

You mean active solar rather than the usual passive solar.

You should stay well away from power lines for your own protection when installing or servicing the bat house. The bats themselves will be fine.

I live in NC and we get so many wasps and we have an owl that lives near the house. 🤦🤦🤦 But we have so many mosquitos because of the wooded area that has a water run off. Have any suggestions...i can't keep checking for wasps...😭

[@h4bats]

Well, I hear painting overhands, ceilings etc... "Haint blue" will deter wasps from building nests, I've yet to test that myself but the theory is that the light blue mimics the sky so the wasps move on looking for something to build under. I can't help with the owl, but they are part of nature and the bats are pretty good at avoiding them. Best bet to help the bats is make sure your bat house is at least 15 feet or so from any perch where an owl may wait for a bat-mc-nugget to drop out of the bat house. With a head start the bats are pretty good flyers. - Thanks for loving bats!

[@Bradyvilleboy]

I have been instructed to treat my purple martin houses with diatomaceous earth to prevent mites. Might the bats also benefit from it?

[@h4bats]

It shouldn't harm the bats, not sure how much value it would be though as most bat houses are open bottomed and most of the DE will fall out, but it couldn't hurt to dust around the bat house with it. We use DE around the base of poles, around our house, around the chicken coop etc... without any issues.

[@h4bats]

What would you tell them? As we don't understand their language completely, we may be saying WARNING! or Go Away! instead of Hey, come on over! There is no known way to attract bats. As for the cedar, if it is new and still has a strong cedar smell, that could cause the bats to shun the roost a while. Also, if it is not painted the bat house may not be getting warm enough. It should be reaching 85 to 100 degrees inside, the bat preferred "room" temperature.

[@olsonlr]
