TomcatRodent Block Expanding Foam Barrier, Fills Gaps to Keep Mice From Entering the Home, 12 oz.

Seems to work, used it in an RV to fill gaps along with some copper mesh dish scrubbers and half inch hardware cloth metal mesh, once those were in place with heavy duty stapler I used this to solidify it in and block all air also. So far so good.

As described

This product works like it says it does. It does have a smell so it’s good to have a fan or ventilation wherever you are using it. It’s a light gray color when it dries.

What else can I say, I had mice then I sprayed the area that the mice were getting in through with the foam and have been mice free ever since.

What is most important to knowIf I had the nozzle as pictured on the advertisement it would have worked fineHowever I had to make do with punching it with a butter knife it was a messPlease send a replacement I have ordered quite a few things I should have some compensation

The stream is to fine. Not sticky enough to stay in place long enough to set up. Can not use overhead. Needs to have an adjustable spray nozzle. Will see if it works.

Used this to fill up holes in the vinal trim around my front door. Solved the yellow jacket problem

I found this product to be excellent. The mice do not try to bore through the applied product however, it does not stop them from making new holes in a spot where the foam barrier had not been applied. I will say that when they do, I am able to continue using the product out of the same can, to plug the new holes that they make. The product does not dry up in the can as other products I have used do.
