Tomcat Rodent Block Expanding Foam Barrier, 12 oz.

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.

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.

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.

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.

Great product

What we liked is that it filled spaces and as far as we can tell it is keeping mice out of our camper. The downfalls were many. It was very messy. We expected mess and used gloves but it was very messy due to bad nozzles and bad tiny hoses. Some of the cans we received would not spray at all. Others had broken nozzles. All had tiny hoses and they were not easy to use or re use. The hoses should be much more substantial and hold up to be able to re use them. Because of broken nozzles, we ended up with the product on our clothing, in our hair, etc, which was a huge mess and a waste of product.

My first time using Rodents block. So far I haven't seen a trace of mice or dropping.

The foam is non-expanding and non stacking. It does not fill holes well unless you can stack it with a floor to hold it. If your hole is in the floor it just falls through. If the can must tilt at all, it does not fill anything and falls back to you. The foam "stream" is the size of the 1/4 inch straw and does NOT expand enough to hold itself, so you must stack it for any HOLE and - it does NOT stack well at all. We wanted to fill holes that were too large around pipes and poorly sealed or filled in our used camp trailer. I did one hole from outside that is now very very messy and never could get more than a thin seal in many stacks of lines of trying to fill the 2" hole with a 1" pipe inside. We returned home and I realized one day too late what was in the box that I intended to return and I bought more than 1 (2 pack). 😢 No idea if the foam works to repel mice. Maybe I will try it in my 90 year old barn. 😂
