Review: Foam Party For Rodents - I live out in an area surrounded by farmland, so the rodent war is not theoretical — it is very much a daily event. I tried everything. I considered all kinds of desperate measures, and at one point I was genuinely one bad day away from gluing individual blades of grass onto a DIY ghillie suit and posting up in the yard trying to track these fellas. Thankfully, this foam showed up before I fully lost my mind. I packed the holes with steel wool, hit it with the foam, and that was that. Problem solved. The rodents met their match, and my dignity was spared just enough to keep going. One quick warning: a little goes a long way. I got a little enthusiastic at first, but this stuff expands and does the job fast. If you’re in a never-ending backyard battle with determined little freeloaders, this is the kind of product that makes you feel like maybe, just maybe, you’re winning for once. 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 - RODENT BARRIER: Our spray foam gap filler is the pesticide-free way to create a rodent barrier - LONG-LASTING BARRIER: This expanding foam spray provides a long-lasting, airtight, and water-resistant bond to most building materials - KEEP MICE OUT: Tomcat Rodent Block Expanding Foam Barrier is a spray foam sealant that fills gaps and cracks to block mice from coming inside your home - HOW TO USE: To apply foam sealant gap filler, attach the reusable straw and spray in crevices inside and outside your house, including the garage, attic, basement, and foundation - TRIM, SAND, & PAINT FOAM: The Tomcat Rodent Block Expanding Foam Barrier is an expandable foam that can be trimmed, sanded, and painted ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07YM5BY58 | | Best Sellers Rank | #4,237 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #22 in Pest Control Accessories | | Brand | Tomcat | | Brand Name | Tomcat | | Customer Reviews | 4.3 out of 5 stars 4,055 Reviews | | Global Trade Identification Number | 00888603441853 | | Item Form | Foam,Spray | | Item Nype Name | Spray Keeps Mice From Coming Inside the House | | Item Volume | 12 fluid ounces | | Manufacturer | The Scotts Company LLC | | Manufacturer Part Number | 4418508 | | Material Feature | Non Toxic | | Material Features | Non Toxic | | Model Number | 4418508 | | Number of Items | 1 | | Scent | Unscented | | Scent Name | Unscented | | Size | 12 Ounce (Pack of 1) | | UPC | 888603441853 | | Unit Count | 12 Ounce | ## Product Details - **Brand:** Tomcat - **Item Form:** Foam,Spray - **Item Volume:** 12 Fluid Ounces - **Material Feature:** Non Toxic - **Scent:** Unscented ## Images ![Rodent Block Expanding Foam Barrier, 12 oz. - Image 1](https://m.media-amazon.com/images/I/61QuN-Td4RL.jpg) ![Rodent Block Expanding Foam Barrier, 12 oz. - Image 2](https://m.media-amazon.com/images/I/81ILnsdFlVL.jpg) ![Rodent Block Expanding Foam Barrier, 12 oz. - Image 3](https://m.media-amazon.com/images/I/71fWWMfb5LL.jpg) ![Rodent Block Expanding Foam Barrier, 12 oz. - Image 4](https://m.media-amazon.com/images/I/712hg7mkh3L.jpg) ![Rodent Block Expanding Foam Barrier, 12 oz. - Image 5](https://m.media-amazon.com/images/I/71fcfxye5KL.jpg) ## Available Options This product comes in different **Size, Style** options. ## 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 ### ⭐⭐⭐⭐⭐ Foam Party For Rodents *by T***R on June 13, 2026* I live out in an area surrounded by farmland, so the rodent war is not theoretical — it is very much a daily event.

The application was straightforward; I just attached the reusable straw and sprayed the foam directly into the crevices, and it expanded nicely to fill the voids completely, creating a really tight, airtight, and water-resistant seal. I appreciate that this is a pesticide-free solution for blocking them out; I didn’t want any poisons around the house, and since sealing the gaps, I haven't seen any new activity, which is exactly the result I wanted. My one observation is that you need to be careful with how much you spray because it expands quite a bit, and while you can trim, sand, and paint it later, over-filling the gap makes the cleanup a little messier than I expected. Overall, this foam is a great, long-lasting physical barrier that gives me confidence my house is sealed up tight against pests. ## Frequently Bought Together - Tomcat Rodent Block Expanding Foam Barrier, Fills Gaps to Keep Mice From Entering the Home, 12 oz. - Steel Wool Mice Control, 2 Pack 3" x10 Ft Hole Filler, Gap Blocker, Barrier, Protect Against Animals in Holes Holes, Siding, Pipeline, Vents for Garden, House, Garage - Xcluder Rodent Control Fill Fabric, Large DIY Kit with Inspection and Fit Tool, Stainless Steel Wool, Stops Rats and Mice --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/179362895-rodent-block-expanding-foam-barrier-12-oz](https://www.desertcart.hr/products/179362895-rodent-block-expanding-foam-barrier-12-oz) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-29*
