Tomcat Rodent 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.

Very sticky. Wear clothes you don’t want to ruin. Make sure you wear gloves. It definitely expands and fills cracks. The tube extender needs to be longer.

Horrific product don’t waste your money. Get proper foam spray, this is garbage

What we liked is that it filled spaces and as far as we can tell it is keeping mice out of our camper. The downfalls were many. It was very messy. We expected mess and used gloves but it was very messy due to bad nozzles and bad tiny hoses. Some of the cans we received would not spray at all. Others had broken nozzles. All had tiny hoses and they were not easy to use or re use. The hoses should be much more substantial and hold up to be able to re use them. Because of broken nozzles, we ended up with the product on our clothing, in our hair, etc, which was a huge mess and a waste of product.

Works great! Good quality & bang for the buck. I highly recommend this.

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.
