Those sizes are also for adult mice. Adolescent mice can fit through smaller holes, then grow off of food foraged in the new environment. I seal everything bigger than 1/4"

[@panoken2130]

He did mention that towards the end of the video

Seeing mice fit through the flat gaps is the most interesting. It seems like that should be impossible but its not. Their actual skull and such must be super small.

I've only ever seen one mouse in my house. It was being thrown around by my cat at the time. They know not to come in any more.

Crazy. I saw a chipmunk get stuck squeezing through the bars of a squirrel trap. I had to lube it with margarine to get it out, I thought I was going to have to cut the trap to free it

[@oneheadofcabbage]

[@mckymcobvious3043]

i had a very old TV in my closet that my parents didn't know about, my mouse once _climbed in_ somehow! for the life of me i could not figure out where that was even possible!

[@jurjenbos228]

Those TV had high voltage in them. You missed an opportunity to have fun here.

[@jimmydesouza4375]

There is an issue with this test which is incentive. A mouse might be able to fit through a smaller hole/gap if it needs to but due to the high availability of food in this test they might not have felt the need to.

[@uchihaitachi4629]

Yes that’s what I was thinking

His metric is the radius, diameter of the hole. 1 inch is about 25 mm in diameter

Well, the metric is from today not the 13-th century 😂😂

[@LukeNukem82]

Just found three mice in my windshield washer reservoir in my truck. Only way in was through a quarter inch diameter hose. No chew marks or holes elsewhere.

[@dalemorris7014]

Great video, thanks! I was just so upset tonight to find droppings around my kitchen counter. I had been renovated last year and the work isn't complete. There's a crack where the seam meets the wall. I stuffed some Xcluder in there. Fingers crossed. I can't throw away all of my kitchenware, any advice on how to properly sanitize after the droppings? Thanks!

[@sergeantnathan6152]

Thanks for this Shawn... just as I thought, "What about a flat gap?"... you had us covered. Very thorough and well done!

Micromys minutus , 5-6 cm long body with 5-7 cm tail , (4"-5" over all) and weight 4 - 6 g (0,18 oz) , that mouse gets in from very tiny holes. 6 mm , 1/4" hole and it comes in . Then again it does not live in American continents .

[@nardopolo7407]

[@ravenlorans]

I have Mice and Rats. Did not know I had a Hole the size of two shoe boxes under my campers toilet until I started getting opossums in it. Then blocked off the hole with plywood but since the camper is on a slope, the mice and rats could now get up onto the plywood and into my camper. I don't/Can't fit under it to seal it. Dual Tone Don't Work! They get use to it. Poison Pellets Don't Work, Not like they use to 30yrs ago. Less poison and eat them like candy. Sticky Pads Don't Work depending on How Cold or Hot it is inside. Seen them walk right over them or peel themselves off.. Snap Traps are also 50/50. Some don't even trigger and others are too slow and mice are Fast.. Don't help the Mice and Rats are Drawn to My Place because of the neighbors. Same with Fleas and Roaches and other shite! Has Not Mowed or Drained his Septic Tank in 20+ years.. You would think everything would want to stay over there.. Peppermint Smell Also Don't Work. "They Hate the smell of ..... ".. Bullshite! "They Can't Burp or Fart and will die from the Gas they get eating Baking Soda/Powder"... Bullshite! I mixed 1/3rd each of Baking Soda, Cornmeal, Sugar.. No Dead Mice or Rats! Keep coming back for more.

[@joekaplowitz2719]

Thank you so much for this presentation. I am working on mouse proofing my studio and this really gives a clear idea of what I am dealing with. Hope you are mouse free!

[@Jangocat]

Yes, they sneak into my house every winter, the cats always make short work of them though. I try to save them (to put them outside) when I hear the commotion, but sometimes I'm not fast enough. Don't want my cats getting a disease from eating one. Barehand catching mice is a challenge, I always felt an accomplishment lol. Surprisingly, they cant bite hard enough to break your skin, at least my skin anyway.

[@L.R.KNIGHT]

So what is often happening, is you have the same population hiding in the walls or attic space in the insulation, and you only start to see them when it gets colder in the walls than it is inside. This is the situation about 90 to 95% of the time in the tens of thousands of houses that I've treated If you're trying to be humane, definitely release the mouse miles away.

[@joeyoungs8426]

When I built this house 20 years ago I ensured no rodent entry. I encircled the entire house up to its waist with metal lathe regardless of whether it was siding or stone. Every piece of exterior trim fits perfectly, no gaps. Being surrounded by woods and brush no precautions were overlooked. Happy to say not a single mouse has breached our threshold. I do late summer inspections to be sure the house is ready for any invasion both in fall/winter and spring. Additionally, all trim and siding is a Hardie product so no wood rot or holes being created by those nasty little devils. The perimeter is also kept clear of debris and our firewood is a 60’ walk from the house.

And then, one day, you leave the door open just a crack while getting groceries out of the car and ZOOM! You've got a mouse in the house. Happens to all of us.

[@geirleirvik1478]

Steel wool and foam does it, make sure no hole or gap is larger than 10mm

[@1rober2]

Mice come in many different sizes depending on species. And plugging the holes only delay them a while if they know that there is food to be found they'll just make a new whole next to the old. Speaking of experience.

[@LamborghiniX101]

i have watched one fit through a vent in the floor with fins in a camper i still cannot believe it did it

[@johnberwyn23]

My mice escaped once after I left the cage door open. I found them hiding under my bed and they ran from me back to their cage, then proceeded to just squeeze through the bars to get back in (avoiding using the open door). This was when I realised they could come and go whenever they pleased.

[@EpicPlayer954]

[@Werevampiwolf]

When my roommate had rats, they were convinced I would fit through the bars because they'd very carefully bite on to the edge of my fingernails and try to pull my hands into the cage. Also one time one of them escaped and we found out that our kitchen cabinet didn't have trim on the side behind the fridge and he was hiding in there. We got him out though, though I had to move the fridge so we could reach him. There were three of us on a rat rescue mission, and it took a few hours, and I'm pretty sure we all looked insane, trying to outsmart a pocket-puppy and having trouble. But rats are smart

They get it in under my sink and there are no noticeable holes or cracks. I get one every 3 or 4 years and I have no idea how they do it.

[@rocksfire4390]

also keep in mind that a fat mouse wont fit in like one that hasn't eaten for a day or more. so go down one size lower then shown just to be sure. not only that but when anything gets hungry they get more willing, just because they didn't enter those smaller openings doesn't mean they can't, they where just unwilling because they just got a feast.

​@Laura-kl7vi He's Canadian. We have to use both because of American products that use Imperial. Metric is just a vastly better system for taking measurements.

[@loganskiwyse7823]

Actually, he should have done it all in metric. It is far more precise for these types of tests. But since he got a standard US drill set for making holes that was just the sizes in the set he used and has no bearing on why he chooses which system.
