Screened Bottom Board vs Solid Bottom Board Which Is Best?

[@nathanrish7099]

Bob, There is no need for grass 2B growing up through screen bottom boards. We use old skidder tires (24" wide) laid on their side. Gives just the right distance to protect the beekeepers back from not bending over too far, protects from dampness of the ground, and lends protection against other insects and varmints. Low to the ground a skunk can rub its tail at the entrance then go off and eat the bees out of its tail. However, if a skunk, racoon, or possum has to raise up a couple of feet to reach the entrance. .then the bees can easily sting them in their not so hairy underbelly and run them off. JE Rish

[@temijinkahn511]

I use the screened bottom board with the insert. If the temperature is going to be below 60 I put the insert all the way in so the bees can keep warm. If 60 to 70 I put the insert half way in. Above 70 I take it out. My hive get direct sun for about half the day and is white. Now, I am a hobbiest and currently only have one hive so my girls get lots of TLC. I had not been paying attention to humidity levels so will factor that into consideration for my insert adjustments.

[@thatguytx]

Thanks Bob! You verified what I am seeing. I'm just a 5th year hobbyist beekeeper. I've made a LOT of mistakes. IMO screened bottom boards was one of them. I just built the last batch of solid bottom boards to convert all my hives. I have three main issues with screened boards - 1) OAV has higher measured efficacy on my solid board hives 2) my solid board hives seem to use more of the brood nest versus leaving space at bottom and 3) I am convinced the light flooding in the bottom of the hive is not beneficial - especially for new splits.

[@josephvogel7234]

This is a pretty gutsy video, even though you didn't attempt to take sides. Thanks for stepping out with good information for both and encouraging BK to choose what works best for them.

[@altaylor293]

It has been our experience that when installing a new queen into a hive with a screened bottom board, there are occasions when the queen will leave. This can be when adding a package, re-queening, replacing a lost queen, etc. Queens don't care for light and the additional light from the open screen can result in her leaving. Our suggestion when using a screened bottom board is to be sure the insert is installed until the queen begins to lay.

[@sharpshepherd]

I really appreciate how you present all sides of the argument for and against without negativity. I have a screen bottom board with the slide out tray only because it gets so hot (and dry) in my location and I want to see how this colony does with the setup. In the cold months I do plan on tweaking it.

@@bobbinnie9872 Question about entrance. I have heard you say that you like to use the 3/8" size but do you have a reducer built into your bottom boards if so to what size do you recommend reducing it down to?

[@donovancoughlin]

Sorry for not including in last question but do you find the bees able to keep the hive cool in the Georgia summer without top ventilation? I'm not far from you and really appreciate the advise from someone in my region.

[@bobbinnie9872]

Hi Donovan. We do not use an entrance reducer unless it's a small colony in which case we we usually reduce down to 2 inches. Also, we don't have problems with temperature with a 3/8 entrance but if you want more air simply prop up the lid in the rear with a small 3/8 thick stick during hot weather.

[@pcelarskisokak]

Great video, a lot of beekeepers don't understand things and work wrong and only create more problems for themselves and bees ..... bottom boards are a tool that regulates the microclimate of the hive ... there is no universal solution, but things must be done according to the target effect taking into account about environmental conditions. Greetings from Croatia!

[@micksbeesstephens5327]

Hey Bob, thanks for the info. I am a serious screen bottom user with about 50 ten frame hives plus 12 to 25 nucs depending on season and all with screen bottoms. I build my own equipment and began using Slatted Racks above the bottom board about 6 years ago , early build up good ventilation and heavy brooding in bottom box was the result. I don't place hives lower than 18 inches so weeds are not a problem . Overall I could not be happier with this set up but I don't try to convince anyone what to use, and we really enjoy your contributions! Great luck, Mickey from Nashville, Tn.

I’m so glad I watched this for the third time in about a year. I live near the Gulf Coast and we don’t have winter..... we have two seasons, summer and not summer this past February’s weeklong freeze being a once in a lifetime event in my 55 years. The point you make about things falling through the screen attracting ants is a very good point seeing that we have fire ants from hell here, however we have temperatures in the upper 90s and lower 100s from approximately mid May through sometimes early October with humidity or shall I say relative humidity in the low 80s to upper 90 percent about 50 weeks out of the year, maybe that’s an exaggeration but not much of one. Lots of folks keep small chickens, some even keep quail if they can in their yards to try to control small hive Beatles Using the birds to eat pupae . Thanx. Enjoy your videos.

[@thedeafcattledog8608]

We have fire ants, and I wondered what would happen if a fire ant tried to go in the hive (I have the narrow excluder on all my hives). I saw a fire ant crawling around on the landing board. It made a dash for the opening, and the guard bee literally picked the ant up and threw it several inches! The ant decided to go do something else after that. An interesting aside, I wonder if having ants in the vicinity of the hive would impact varroa infestations. As in reduce them since ants are formic acid factories. Would be interesting if someone had studied that.

[@stufarnham]

A late comment on this question. I have always used screened bottom boards, first because it was how I was taught and second because we have very hot (but dry) summers and I figured the added ventilation would be helpful (I also have screened inner covers I put on when the extreme heat hits.). My honey yields were poor this year because a couple of our main flows were knocked down by weather. I also had a lot of first year hives from splits and swarms that did not build a lot of stores. As a result the robbing has been as bad as I have ever seen. I noticed that robbers were drawn to the screened bottom boards and covers by the honey smell. It is easy to pull the screened inner covers but not the bottom boards. As a result I have decided to rotate out the screens bottoms opportunistically and replace them with solids. Just one guy’s experience, FWIW.

We have high humidity and lots of rain at times in western NC which causes ventilation nightmares. I have used solid bottom boards for 30 years and screened bottom boards for the last 10. I do use the slide in covers through the winter and shim the top cover year around to try to help control condensation. You have brought up some things i have not considered and I am heading back to solid bottoms for some splits this year. I like the smaller opening in the hive entrance but still see gnawing of the comb at the bottom of the hives. I have reversed my deeps twice this year and have noticed that the queen likes living upstairs. The brood patterns are better and the gnawing isn’t as bad. And the solids last longer while the screened ones have too many places for decay to get a foothold....yes i am not the best carpenter. I may go back to solids completely this fall. Your presentation was excellent and your points well taken. I just have been having 2nd thoughts about this topic for the last year.

I use screened bottom on most of my hives and I can verify every word of this video. Thank you

[@markray6000]

I had the same thoughts as you on the humidity control. An open bottom allows the moisture to evaporate and dissipate too quickly which in turn would make the bees work harder at getting more water to cool the hive or maintain humidity. I stopped using screened bottom boards after my first season as a beekeeper. Subscribed.

[@bobbinnie9872]

Thanks.

[@luci75d76]

I have for all stationary hives the 3 version of the screen bottom boards. But in winter time in top of the slide part I put 3cm of polystyrene cover up in newspaper 📰 and will be isolated for winter very well. Important is the distance between slide and mesh should be enough to fit at list 3cm of polystyrene. I have hives woh 5 cm because in winter hey are hit by a heavy wind. But in summer is very useful especially late June , July and August. After that I put the slides back. In spring fro sure you have to keep slides inside and even the polystyrene until mid May. Just for the same reason as you mention to have. a fast build up colony. I do the mite treatments on the tray and any other fumigation. It’s ventilation. Is mite control. A bit of all. You have to limit your self to weather and where you live them or if you are close to the bee yards to keep an eye on it. Bob do industrial system and for sure only solid bottom boards is needed. Same as I have for pastoral trucks. It’s all solid but screens above with no lids in summer 😂😂😂

Spot on! Thanks for your experience and honest insight to this 'over debated' subject. Common sense rules! When I still was assessing their use, I experienced wax moths will lay eggs/cocoons under the screen board and the when the larva emerge they are small enough to enter the hive through the screen. Also, during robbing season the hives with the open bottoms were constantly harassed as their smells were wide open and very attractive to bees, wasps, yellow jackets. Thanks for taking the time to make all your videos. We all benefit from your knowledge and experience.

Since I am trying make some of my hive components myself, I prefer solid bottom boards because they are faster and cheaper to produce. One of reasons why are screened bottom boards relativly popular here in Europe is that you can get financial support from EU for them (about 30% of their price here in Czech rep.), which make them cost roughtly the same as solid ones. Because of that most of bottom board sold at stores (at least here in Czech rep.) are screened ones.

Hi Bob Iv still not found the Queen, but it’s laying brood, so she’s in there somewhere. Right the question is, if I have 2 or more weak hives can I add a double Queen excluder between the brood boxes so I can utilise the workers to build out the hives

[@bobbinnie9872]

If you are referring to setting a weak hive over a strong colony to gain more bees the answer is yes. Excluders used with a sheet of newspaper with a thin cut in them work for this. Once they have gained some population you can move them away.

[@citrumpet1]

I think you're right and will probably switch from alluding tray to solid on all my hives. One thing I will miss though is after an OA vape looking to see the mite drop on the sliding drawer the next day. Instead of counting mites in all my hives I could just vapor them all once and if there are none or just a few mites that dropped I will know I don't need to treat it. If there's higher mite drops then I can do a wash on those hives. This seems faster than doing mite counts on all the hives in the apiary. Any thoughts on this? I know a mite drop is not an accurate percentage count but it does show a lot.

[@bobbinnie9872]

You're right that a screen bottom makes it easier to monitor mites. Many people use them for that alone. And if you are familiar with what to expect relative to your colony size it ca be a great tool.

[@donaldsmith3048]

For someone like me that doesn't know much. Would the screen bottom board be good for cleaning the bottom. With the pull out white plastic it can be pulled out cleaned and put back. I am thinking of someone with just a small number of hives. I also thought that a peace of light plywood under the screen bottom with the plastic in there would be better at keeping in the heat in the winter and can be removed in the spring. I understand for a big system with a lot of hives this is something more to do and keep track of. But for someone with only 2 to 8 hives it would not be that big of a problem. I must tell you I don't have any bees yet, I am learning by watching the videos. So if what I ask sounds like I don't know much it is because I don't know much.

[@thedeafcattledog8608]

I am new to beekeeping just starting this year. The kits I bought all have screened bottom boards because that's what the person I bought them from uses (he has ~2k hives, I figure he must know something). I went to a local class and the instructor told me some of the same things Mr Binnie said about the closed bottom boards, and she was moving to those. I saw several small hive beetles in her hives. I haven't seen a single one in mine so far. I'm not sure about using closed bottom boards here, temps are often over 100 in the summer, humidity today is 60%, it's freaking hot, and my hives are on concrete blocks which form a solid foundation with no gaps, so no air underneath. Concrete in the sun here gets so hot you could cook an egg on it. I am thinking instead of using just the inserts this winter, using some foam board insulation or something underneath them, as those inserts do seem flimsy and not very warm. One thing I will say about ventilation - the better it is, the less disease there typically is, at least with humans. I would imagine that might apply to bees too. As for them being closed up in a tree - a tree is not a box. The box is too thin to provide the same sort of insulation that a tree would. Therefore, I would think that temperature control would be much more difficult in a closed-up box than in a closed-up tree.

[@bobbinnie9872]

A mouse generally can't squeeze through a 3/8 entrance so you don't need mouse guards in winter and there is much less bridge comb between the frame bottom bars in the bottom box and the bottom board. You also are less likely to need entrance reducers in winter. When I started commercial beekeeping on the west coast I rarely saw 3/4 entrances and concluded they weren't necessary.

Thankfully we do not have a hive beetle problem bad enough for us to have to resort to treatments. We do use yards with full sun when possible. I definitely see more beetles in shady locations.

I had a friend that had a bad problem with beetles and he soaked the the ground around his hives with Guard Star and he said the problem went away. Like me he doesn't like using chemicals on anything but he was desperate. I've wondered if copious amounts of diatomaceous earth or pulverized lime spread under the hives would have the same affect.

Is it possible to switch from a solid bottom to a screened bottom only while doing powdered sugar treatments and then go back to solid bottoms or will the bees not like the different environment?? Thanks so much for all your advise!

[@bobbinnie9872]

It should work fine.

[@mer-oneralphjr.bolinto6515]

what is the specification of the screen you used sir?

[@bobbinnie9872]

Most screen on bottom boards in the US is 1/8 inch hardware cloth.

What guage or screen size do you use in your bottom boards and snelboards?

Hello. What is your opinion on polyhives with screened boards?

[@ThEcLoUdBuStEr]

IMHO with screened bottom board you have to have top of the hive without a ventilation + 1mm aluminum screen. To prevent many problems there should be 6-7cm form screen to a frame.

Is it necessary to have screen bottom boards on my polystyrene hives? They now have solid bottom boards.

[@bobbinnie9872]

I have not ever used polystyrene hives. I wonder if they hold greater amounts of condensation. If they do screen bottom boards could be helpful. Combating condensation is one of the strong points of screen bottom boards.

Since I am in Canada and our summer is short and winters are long so I am a solid bottom board it never gets that hot here in summer. So that said I use a solid bottom board all year long I donot own a screened bottom board my 2 cents worth

You mentioned alcohol wash... what is that? I'm still learning. 😊

[@bobbinnie9872]

It is a technique for checking mite percentages in a colony. There are several versions. We use this item: www.dadant.com/learn/check-varroa-mites/

​@@bobbinnie9872 have you ever heard or used Varroa Tester 3 in 1 - you use powder sugar instead of alcohol. You keep those 300 bees alive and throw them back to the hive after test.

Hi, i’m a new beekeeper, could you help me out by answering a question? I want to put a screen bottom base on a beehive, but right now all my hives have screen top cover. Would you recommend a top, bottom, or both? Which one is better? Thank you.

[@bobbinnie9872]

I think a screen bottom board would be better than a screen cover or both.

I’m sorry to bother you again. Yesterday i put only 1 screen on the bottom board and today i checked it and under the screen there are a lot of bees all together, do you know what I need to do?

[@bobbinnie9872]

@@jorgogjika646 One of the potential problems with screened bottoms is what you are describing. Confused bees cluster under the screen instead of using the entrance. They will figure it out in time and start using the entrance.

[@nataliaroberts8443]

@@bobbinnie9872 why not both in summer ? We have high humidity in NoVA during summer months. What are possible problems ? I had noticed that since I placed them both, there is no beard, but I am a newbie and, surely, do not have anything to compare to.

[@ApiaryManager]

The purpose of the natural mite drop using a screened bottom board is to provide an initial assessment of the infestation at a time when it is too early in the season to perform other tests. It is an estimate, just as other tests provide especially since most varroa mites will reproduce in sealed brood when it is available.

[@bobbinnie9872]

Thanks

What do you think of a slatted bottom board

[@bobbinnie9872]

Some beekeepers say they help with swarming and some say they help with overwintering. I don't have any personal experience with them so I can't say.

Thanks for the comment.

[@danskisbees7348]

Hello Mr. Binnie, I agree, I've been thinking about this for a while too. I think it's harder for the bees to keep the hives cool with the screened bottom boards. It's kind of like running the AC with a wall missing. I'm in Eastern Texas and it gets really hot. Yesterday, the heat index was 108F, with 37% humidity. This Fall, I plan to change them out. Also, if I can smell the hives when I walk into the apiary, I imagine robbers can smell them from way off. Here are the bees working to keep the hive cool with a screened bottom board. kzbin.info/www/bejne/mam3lJiEm82saZY

[@brianmahern6699]

Why do you prefer 3/8 entrance?

[@bobbinnie9872]

With 3/8 mice generally can't get through, there is less of a need for entrance reducers in winter, less burr comb or "ladder comb" between bottom bars on frames and the bottom board because it is closer to proper bee space, and last but not least when I got started in Southern Oregon everyone I knew, both small and large, were using 3/8. I never saw anyone use a 3/4 entrance until I moved to Georgia where most beekeepers seem to use them.

[@Atlas531]

@@bobbinnie9872 , I have had the same experience with the burr comb. With the 3/4" spacing, the burr comb gets so bad sometimes I cannot pull the frame out of the box without destroying a lot of cells on the neighboring frames.

[@rab2020]

Any comments on screened inner covers?

[@donaldgulledge729]

Why can't you have a solid bottom board, that has a screen above it and a pull out tray as well? Why not combine the best of both - the only thing you wouldn't have is the increased ventilation - but you could monitor for mites, but have the solid bottom board "feel" as far as the bees are concerned - dark, sealed and not have the drop of material under the hive.

[@bobbinnie9872]

That's a good choice. We sell many of those in our store.

[@larrytornetta9764]

Solid bottom boards collect wet moldy bees in the winter.

[@IceBug1337]

In rare cases mice eat through the screen in german winters.

You mentioned black foundations , are this plastic foundations? If so aren’t you Concerned about the brake down of plastic over time and contaminating the honey with micro plastic. Plastic of any grade is made from nasty chemicals. The same concern should be by using flow hives. Cheers

[@bobbinnie9872]

It is black plastic foundation. And as with anything made from plastic (most of what we touch) there's a cost and a risk. The plastic foundation we use is made from food grade plastic which helps.
