Great Stuff 99112809 SMART DISPENSER Pestblock, Gray

This stuff is awesome. Filled all the gaps around my chicken coop. Can and nozzle are easy to use. No mess. I stored the can upside down and was able to reuse it many times after the first use.

Stuff works great, haven't even since signs of a mouse since we used it around seals and pipes. Very sticky when using it, definitely wear gloves.

This is fairly easy to use and works well. It is an ugly yellow color foam. The foam expands slowly so be prepared to scrape off the excess or touch it up over 15-20 minutes. Once it dries you can’t make adjustments so be vigilant and check on it.

Fifteen years ago, I discovered a method that has proven effective: installing copper mesh secured with Great Stuff 99112809 Smart Dispenser Pestblock foam under the bottom edges of my home's James Hardy cement siding. This combination has successfully prevented entry from various pests. The Pestblock foam is particularly noteworthy for its durability and pest-deterring capabilities. However, application can be messy and requires careful preparation. I learned the hard way that protective gear such as gloves, long sleeves, and pants are non-negotiable, as the foam adheres to skin stubbornly, leading to an uncomfortable removal process. I'm currently applying the same technique to seal the bottom openings of a steel shop building, aiming to deter mice without creating an entirely impenetrable barrier. Despite the application challenges, Great Stuff Pestblock remains my go-to solution for effective pest control in a rural setting. Its performance outweighs the cleanup inconvenience, making it a valuable tool in maintaining a pest-free environment.

The foam does expand and covers what you need when applying to surfaces. Adheres to the surfaces The problem is that the sprayer doesn't always work well. Foam starts grey but yellows after it dries.
