Rated 3.9 out of 5 by 55 reviewers.
Rated 5.0 out of 5.0 by The Trick Is... This is an Excellent product.. Use it with a Wire mesh to keep Mice and Rats away!=D I used it and found a partially chewed Foam..seems like the rats unable to chew through the heavy gauge mesh, It was semi sealed in with the foam. Update-1year Later Sealant & Wire are still holding strong. Best Combo if you have heavy Big Vermin Trying to get In. December 20, 2014
Rated 2.0 out of 5.0 by Not great stuff... I greatly hate this stuff. It is difficult to control as it comes out fast and expands so much. There is no way to make a small bead and a large bead will press so much as it expands that it will warp window and door frames. I have used a window and door foam sealer that goes on with a gun and can be adjusted with a needle valve to lay anything from an 1/8" bead to filling 1-1/2" gaps. It doesn't warp the frames and the flow with practice can be controlled completely by the trigger. It seals at the nozzle tip so you don't have plugged straws as with Great Stuff. One can not always just seal without having to stop for any reason before the can was empty. I've had to throw out many partially used cans because the straw plugged. I do like the anti-vermin formulation. February 10, 2015
Rated 5.0 out of 5.0 by great stuff for sure I have read the people who have had trouble with this or low expansion. This is not the largest expansion but I have had great luck with as it expands alot. I have filled holes way over the 1" that is recommended. If it comes out like silly string you either had it outside and it froze, or more likely you did not shake it enough. You have to very vigerously shake the can for about a minute to get best results. This also spreads the pest block material around more in the can to be more even. If you want a product that you can reuse the can get the pro stuff. You will be able to reuse the can and the nozzel if you clean it out after each use. October 14, 2013
Rated 4.0 out of 5.0 by Works Great for Stopping Mice. My house has been invaded by mice. The exterminators (two different companies) came and laid down some traps. Zero captures for theme. I have exterminated 7. As for the foam, mice won't touch it. They get angry and move. The price is high. If you buy a case, a little discount would be nice. The foam is easy to remove from the floor or wall aft it drys but don't get it on your clothes or hands. It's a struggle to remove. Biggest complaint, the foam doesn't always stick to a vertical hole so I suggest checking all vertical cracks you fill. The application tube could also be longer. June 6, 2013
Rated 5.0 out of 5.0 by It works I've used this product before and it works great. Helps seal all the tiny cracks in my older home to keep the pests out. February 17, 2015
