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) Review: 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. ## Features - SMART DISPENSER Reusable up to 30 days. No drips, less mess.

Dear Mr. U******ff, Thank you for your inquiry. Great Stuff™ Pestblock Insulating Foam Sealant is a pesticide-free method to physically block critters, bugs and other pests from your home. The formulation contains an additional distasteful agent that strongly discourages consumption of the foam and protects the integrity of the physical barrier, keeping pests outside where they should be. The sealant blocks insects and pests from entering the home by sealing gaps, cracks and holes where they commonly enter. In addition to blocking pests from the home, Great Stuff Pestblock Insulating Foam Sealant air-seals holes, gaps and cracks to help keep air from leaking out of or seeping into the home’s envelope, saving on heating and cooling costs. Best regards, _______________________ Mike DuPont Contact Center Regional Telephone Numbers DuPont Website Facebook logo Indeed Logo Twitter Logo Original Inquiry Information provided: I'm trying to find out the difference between pest block and the other products. I have used several your products including the pond one but the pest block is new to me. I've tried to find the information and I see nothing that makes it different in your literature. I found one post that said it had denatonium benzoate but I don't is in your literature or msds. Specifically what makes it different? Specific Products of Interest Application Exterior Foundation issues Great Stuff™ Pestblock,Great Stuff Pro™ Pestbloc **Q: can this be used to fill in crack in concrete?** A: Yes but only a large deep crack. It will dry and swell out of the intended space and need to be trimmed. It will not be hard like concrete, and it doesn't stay gray. It turned yellow like all other Great Stuff I've used. **Q: Can this be use to insulate outlets? We have ants coming in and out of ours.** A: Do not use any expandable foam to seal outlets. It can push things out of place; additionally, it makes it very difficult and messy to ever change your outlets later on, as the foam expands and can seal up the wires. I have seen this once, in a house, and it was not a good idea. To seal things up, I would suggest silicone caulking or something that will not expand. **Q: can a small amount of the spray be flushed down the toilet?** A: No! Please don't do that!!! This stuff is not only water resistant (won't dissolve!!!), it is rigid and would be like flushing a plastic toy down your toilet! Just toss it in the garbage! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by T***S on 7 February 2026* This product does exactly what it’s meant to do.
