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.

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.

Effective Barrier for Peace of Mind
I bought the Tomcat Rodent Block Expanding Foam Barrier because I was tired of finding evidence of mice sneaking into my garage and basement through small cracks in the foundation and around pipes. 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.

Seems to work.
So far so good. I was having trouble with rodents getting into my duck house and chewing on the ducks. I filled any cracks or holes I could find with steel wool and sprayed this over it. Easy to use and it's holding up well so far.
