This insulating foam sealant expands to take the shape of gaps and cracks to block mice from coming inside your home. It is the pesticide-free way for DIY homeowners to create a rodent barrier and provides a long-lasting, airtight, and water-resistant bond to most building materials. Spray Tomcat Rodent Block Expanding Foam Barrier in crevices inside and outside your house, including the garage, attic, basement, and foundation. It can be trimmed, sanded, and painted if desired. To use, shake well, firmly screw the included straw onto the valve stem, then spray foam. When done, bend the straw back and press tip fully over the seal on the back of the trigger. To reuse straw, cut, discard tip and cured foam near the end of the straw. Bend the straw back to a straight position and spray foam. The recommended usage temperature of Tomcat Rodent Block Expanding Foam Barrier is 60 to 90�F. See product label for complete instructions. Review: Works well - This mice foam did exactly what it’s supposed to do. It expanded well into gaps and cracks, creating a tight seal that’s clearly difficult for rodents to get through. Application was straightforward, and it adhered nicely without making a mess. Since using it, I haven’t noticed any signs of mice getting back in, which is the real test. It’s held up over time without shrinking or breaking apart, and it gives peace of mind knowing those entry points are properly blocked. Overall, it’s an effective, no-nonsense solution that delivers on its purpose. Review: It works GREAT - I don't have any more mice. I pulled out the stove and there were wholes around the plug where they were getting in. I stuffed scouring pads in the holes and then sprayed this stuff in and around the area. I covered all loose boards and under the sink around pipes etc... I've not had any issues with mice after this. My advice before using the can. First figure out where you want to spray, don't go looking for a plan after opening. The can can't be reused as everything stops working. The product slows down coming out of the nozzle if you take too long. so MOVE QUICK. USE GLOVES: If this gets on your skin and cures, it will be there for a week with constant working to get it off. Its so bad that there will remain residue on the skin no matter what. Your skin will naturally have to sloth of old scaled skin to get it off completely. I had to use nail polish remover. As I said it got the bulk off but again, skin had to sloth off. ## Features - Tomcat Rodent Block Expanding Foam Barrier fills gaps and cracks to keep mice from coming inside your home - Spray this rodent barrier in crevices inside and outside your house, including the garage, attic, basement, and foundation - Expanding foam provides a long-lasting, airtight and water-resistant bond to most building materials - This spray-on sealant is specially formulated to block mice - Pesiticide-free way to keep mice out of your house ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07YM5BY58 | | Brand | TOMCAT | | Country of Origin | USA | | Customer Reviews | 4.2 out of 5 stars 3,681 Reviews | | Global Trade Identification Number | 00888603441853 | | Item Form | Spray | | Item Nype Name | Spray Keeps Mice From Coming Inside the House | | Item Volume | 12 Fluid Ounces | | Manufacturer | Tomcat | | Manufacturer Part Number | 4418508 | | Material Feature | Non Toxic | | Material Features | Non Toxic | | Model number | 4418508 | | Net Quantity | 340.1943 Grams | | Scent | Unscented | | Size | 12 oz. | | UPC | 888603441853 | | Unit Count | 340.1943 Grams | ## Product Details - **Brand:** TOMCAT - **Item Form:** Spray - **Item Volume:** 12 Fluid Ounces - **Material Feature:** Non Toxic - **Scent:** Unscented ## Images ![Tomcat Rodent Block Expanding Foam Barrier - Specifically Formulated to Block Mice, Long Lasting and Pesticide Free, Foam Spray Keeps Mice from Coming Inside The House, 12 oz. - Image 1](https://m.media-amazon.com/images/I/61QuN-Td4RL.jpg) ![Tomcat Rodent Block Expanding Foam Barrier - Specifically Formulated to Block Mice, Long Lasting and Pesticide Free, Foam Spray Keeps Mice from Coming Inside The House, 12 oz. - Image 2](https://m.media-amazon.com/images/I/81ILnsdFlVL.jpg) ![Tomcat Rodent Block Expanding Foam Barrier - Specifically Formulated to Block Mice, Long Lasting and Pesticide Free, Foam Spray Keeps Mice from Coming Inside The House, 12 oz. - Image 3](https://m.media-amazon.com/images/I/71fWWMfb5LL.jpg) ![Tomcat Rodent Block Expanding Foam Barrier - Specifically Formulated to Block Mice, Long Lasting and Pesticide Free, Foam Spray Keeps Mice from Coming Inside The House, 12 oz. - Image 4](https://m.media-amazon.com/images/I/712hg7mkh3L.jpg) ![Tomcat Rodent Block Expanding Foam Barrier - Specifically Formulated to Block Mice, Long Lasting and Pesticide Free, Foam Spray Keeps Mice from Coming Inside The House, 12 oz. - Image 5](https://m.media-amazon.com/images/I/71fcfxye5KL.jpg) ## Questions & Answers **Q: Can this be put under radiator without fire hazard?** A: I used this product in May. It worked very well. I was worried about the radiator in the home because that's where I put most of it. So far no problem but it did sit and harden for 5 months. **Q: Does it have a smell ?** A: Didnt notice any smell. Used outside though **Q: Can you use the can upside down** A: I didn't need to have it upside down, but I definitely had it sideways and it filled crevices great. If upside down is a problem, try sideways and use your free hand to point the end of the straw where you need it. **Q: Found a gap between siding and wall pointing downward. Mice climb up and get inside. Will the foam hold up and not get pulled down by gravity?** A: The foam dries very hard! I don't see how mice could or would eat thru all of that! But maybe I would be surprised at what mice can do! I have an unfarmed 40 acres next to me so there are many mice in the field! I had to hire a pest control service to put bait boxes in different areas inside and out! It's costing me around $40.00 a month! I didn't have mice in the house until I had a walk in tub put in! They did plumbing under the house and things were not sealed up tightly, so hello mice! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works well *by A***R on 23 April 2026* This mice foam did exactly what it’s supposed to do.
