Rated 2 out of 5 by Pest Block Doesn't block red squirrels. The squirrels also ate away the foam sealant. December 10, 2014
Rated 1 out of 5 by Mouse ate a hole ate through it Doesnt wok for mice. I located where a mouse was getting in. Used this last night and woke up this morning with a perfectly chewed hole through the Pestblock. October 20, 2014
Rated 5 out of 5 by Works Exactly Like it Claims The pest block was easy to apply, filled in the spaces where it needed to be. Dried quickly and stayed in place, which was a real plus. The amount of product in the can is amazing. I have used this product three times now and would have no concerns about purchasing and using it again. Mice and other critters do not appreciate this product. September 3, 2014
Rated 4 out of 5 by Great Concept This is a great concept that eliminates the need for stuffing holes with steel wool. However, there is a learning curve. I first watched videos on You Tube but still made a mess with my first pass. But at least the holes are closed. I have to re-watch the videos on how to clean up the mess and to use it again for the rest of the holes/gaps. I will definitely be purchasing more of the Foam Sealants to address all the gaps as I have a rodent problem and using this gets to even the tiniest hole that the critters can squeeze through.

Rated 5 out of 5 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
