    Hi everyone I’m looking for some ideas to seal where my barn walls meet the concrete floor it’s a 30x60 corigated steel pole building. I put boards all at the bottom and sheet metal but still no good mice are still getting in and running my ****! I was thinking spray foam but I feel like they will just eat there way through that.
    Any ideas would really help thanks!

    I remember one farmer telling me that he used the spray foam for sealing gaps in his old silos. IIRC the mice didn’t like to chew through it.

    Mousetrap it till they are gone. Put scented dryer sheets in car that is supposed to help.

    I do these two things. I've heard varying opinions on the dryer sheet thing, but so far so good (and the cars always smell nice!). It seems every fall/early winter I'll snag a few right away in my traps and then usually won't get but maybe 1 more for months on end. Then next fall, same story. Sealing up a pole barn to be mouse proof is a tough task.

    Sheet metal flashing strips bedded in construction adhesive and nailed to the base plate. If you have a nail gun its a breeze (into wood) . If its steel to concrete, TECH SCREWS (self drilling hex head sheet metal screws) can be had with a rubber washer for rust. Use the new gorilla glue. Wash the concrete first and apply the glue to the dampened substrate. It expands 3X and gets hard as a rock. The seal has to be 100% as those little guys dislocate their skeletons and can squeeze in almost anywhere! Im lucky here so far; not even a single turd in either shop!

    Being corrugated theres also the sackrete (mortar) approach. Just hard to keep it neat looking

    Being objective, a cat works wonders, or go to a place like fleet farm for some wolf or fox (predator) wee-wee scent for the outside. Its de-scented for humans but works for critters. I had to use it at the old homestead since the rabbits were eating all my flower bulbs. Sticky glue traps with peanut butter works too, but word gets around ha-ha. Ive also heard a string of moth balls around the perimeter works but only till they wash (evaporate) away.

    Good luck! ws

    This was pretty easy to do: measured a set distance from steel, trim the wood here & there where the gaps were different, pavers held the wood in place, trowel smooth. They're not chewing thru that.

    I used dryer sheets and mint-scented plastic bags inside my cars. It seemed to work. I also used Victor mouse traps when I was around. When snowbirding I would just set a bunch of the victor traps and see what I had in the spring. I didn't like to use poison for fear that somebody's cat might get at it. Our barn was stick-built on a (very) solid foundation, but as it was originally built as a (gasp) barn for horses and hay, we purposely didn't go to great pains to make it absolutely tight.

    I've used the bucket trap for years and it works great ! I spread a little peanut butter on the middle of the roller to make it more enticing. Roger

    Thanks everyone for your help those bucket traps are amazing! Think we are leaning towards pouring concrete some what like a footing to fill gaps and we ordered new roll up door!

    Peppermint oil on cotton balls. Mice hate it. Mothballs work too but lots of people don't like that smell. I say it's 10x better than the smell of mouse piss and destroyed car interiors

    @Stan1971 I learned something from an exterminator buddy that has helped with several mouse issues. Mice use their whiskers to feel for air flows (a breeze)-- so they won't bother trying to get into something unless they sense there is a space on the other side... So using spray foam and caulk to seal gaps is key. If they don't sense the air flow they won't try to get in/under something. (he explained that this is also why you ALWAYS foam around pipes and wires in a house -- even between floors -- so they won't try to get chew a bigger hole to get to another space) I've since used this advice to seal several buildings -- it seems to have kept them on the outside. In places where I thought the spray foam might be vulnerable, I wedged some of those stainless steel pot scrubbers you buy at the supermarket and then foamed them in. -- I think your mortar plan will do the same thing but I might still foam some corners, etc
