Great Stuff 99112809 Smart Dispenser Pestblock, Gray

I purchased this Great Stuff Pestblock foam after inspecting my basement and finding a couple of small openings where rodents or other unwanted pests could potentially get inside. Sealing these areas was important to me, and this product worked exactly as I expected. I have used Great Stuff products for many years, and I have always been impressed with their quality and reliability. The Smart Dispenser makes applying the foam much easier because you have better control over where the product goes, and it helps reduce waste compared to some other foam sealants I have used in the past. The foam expands well to fill gaps and creates a solid barrier once it cures. It adheres well to different surfaces and is perfect for sealing around pipes, openings, cracks, and other areas where pests can enter your home. The only thing to remember is that this foam expands, so you want to apply it carefully and avoid overfilling an area. A little goes a long way. Overall, this is a high-quality product that does exactly what it is designed to do. I have trusted Great Stuff products for years and would highly recommend this brand to anyone looking to seal gaps, improve insulation, and help keep unwanted pests out of their home.

This product does exactly what it’s meant to do. I used it to seal an old hole on the side of my garage that previously had plastic stuffed into it to keep rodents out. I added a bit of copper mesh, and the foam flowed right through and expanded all around it, sealing everything up nicely. As a first-time user, it did get a little messy, but that was more user error than the product itself. It’s really a single-use item, but that seems standard for this type of product. Totally worth the money—especially for the peace of mind and not having to keep putting the job off. I would definitely recommend it. Pros: - Works exactly as intended - Expands well and seals thoroughly - Great for pest and rodent prevention - Easy to apply once you get the hang of it - Worth the cost for peace of mind Cons: - Can be messy for first-time users (likely avoidable with experience)

I bought a house two years ago that was remodeled. This year for whatever reason the local rodent population decided to move in when it got cold. The remodelers had created tons of highways for the little buggers and never bothered to close any of their holes up. I had holes around the pipes for my water heater, holes around the drain pipes under my sinks and the guy that put the dryer vent in didn't even fill up the gap around the dryer vent or put a screen on it where it goes outside. When using foam to fill a gap where rodents are a concern, it's recommended to add either steel wool or copper wool/fabric to the patch because they hate chewing on metal. This foam also contains something the buggers are supposed to hate the taste of. So squirt in some foam, lay a piece of your metal material over that and squirt in a bit more foam to make a sort of sandwich which hopefully they won't chew threw and get back in. A field mouse is small usually around an inch and their skeletons can compact to the width of their heads so most mice can enter through a hole the size of a number two pencil. Once you block off their entry method you'll undoubtedly trap a few in the structure. I hate the idea of poisons around my dog not to mention other things in the yard that can and will get into it. The rodent metabolism cannot handle baking soda for whatever reason, it may take a bit longer to kill them than poisons but it's safe around the other critters in your house that belong there. At this price someone's making a whole bunch of money off this product and despite what they claim on the can, once you open it you only have a few days to use it. The stuff dries out fast and there is no way to clean the nozel if it gets clogged. There is a professional sized package of this and a supposedly cleanable application nozel but if you read the reviews on that setup that thing clogs up just as fast as buying a can at a time. We clogged up all the grand canyons through the wall under the sinks etc. I have heard what sounds like chewing going on at least one spot but haven't seen them get back through yet. I suppose only time will tell if this worked.

Great Recommended product after I asked the contractor who used it between floor and walls! Asked to let dry atleast 24 hours or more!

Away with ye thou offensive air gap! Thou shalt not disturb my cozy warmth with your frosty and intrusive finger. The brand says it all, GREAT STUFF!

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.

Update 12/1/2024: Previously using the foam applicator tube had been challenging and messy. Yet, I don't appear to be smart enough to operate the new "Smart Dispenser" tip. I simply can't get the Smart Dispenser tips to work properly or sometimes at all. I'll try another brand with the old tip style. Living in a rural setting means taking a hands-on approach to keep unwanted critters at bay. My proximity to neighbors with cattle and chickens, along with my encounters with various small wildlife, necessitates a strong defense against potential intruders. 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.

I bought this to deal with a mouse problem and expected it to dispense like Great Stuff foam. Instead, it started hissing and spraying out from the bottom of the applicator, making a huge mess all over my kitchen sink and my hands. Honestly, I saw other reviews mention this and figured I’d be careful. I made sure the applicator was tightened down as much as possible. It wasn’t loose and didn’t move at all, but it still leaked. I tried to use it anyway, but it was very hard to control. Even when I got it into the mouse entry point, it didn’t apply the way it should. I expected a neat, controlled bead like the pictures show. What I got was uneven, sloppy foam that spread everywhere. Once you start using it, you basically have to rush because you only get one shot. The foam clogs the applicator, so there’s no "saving it for later". Total mess and a complete waste of money. I was stuck with a big cleanup, a huge bag of steel wool I probably won’t use, and no real confidence that this will even solve the mouse problem. It just made things worse. Luckily, this is a rental apartment and not my own house, so someone else will ultimately have to deal with the aftermath. Still, I would recommend choosing a different product. Don’t trust the “no drip” claims or the marketing.
