## Description

Great Stuff 99112809 Smart Dispenser Pestblock, Grey

Review: Worked Perfectly for Sealing Out Rodents - 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)
Review: Must have for every house - Worked like a charm. Sealed up where mice were getting in through a hole.

## Questions & Answers

**Q: will this keep mice out?**
A: From the manufacturer since I requested how it deters critters from eating it.


 
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,

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?

**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!

### ⭐⭐⭐⭐⭐ Must have for every house
*by T***A on February 21, 2026*

Worked like a charm. Sealed up where mice were getting in through a hole.

### ⭐⭐⭐⭐ Could Be a Bit More Gray
*by J***N on January 4, 2026*

Worked as advertised, I always have great luck with Great Stuff branded products. Was really hoping for a more substantial gray tint than the end result though. This may not suit your needs if you're looking for a dark gray filler. Still, it expanded fully and sealed well regardless!
