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.

Doesn’t work!! Waste of money.

I like the Tomcat brand but the wand/spray attachment for this can of spray foam snapped off when I pulled the trigger. I was able to use the spray by holding can basically upside down and aiming the nozzle in the can directly at the area I was sealing and pressing it from the side of the nozzle. It applied kind of sloppy using this method but I did get the openings around my drain pipes sealed. I doubt that I will be able to use this can on the other areas that I am planning on sealing.

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

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