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.

Quick Foaming and sticky
Pretty useful for filling gaps. Stuff is very sticky similar to foaming glue. Use this with some steel wool to patch up a mousehole in my apartment and to seal some spaces near the sink where german roaches were getting in. Hopefully this stuff will keep them out. It was a pain to clean up the excess foam since it is extremely sticky. Was able to get most of it with warm water.

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.

Great for exterior penetrations!
This stuff is great! We have a problem with a hoarder neighbor and the newest gift from all their junk was mice! They were getting in the house and we were having to trap and use steel wool to plug any spot we found where they may be getting in, but I got tired of stuffing holes so I looked for a solution and found this! So great! Filled all the little openings I found outside around the house and it expanded plugging any little area that needed it. Hardens and is easy to cut or sand down. Definitely recommend to anyone with little spaces to fill. Very easy to use, but it did take a few tries to get the hang of applying it efficiently.

Horrible
Can't give it negative stars. The straw only works for a while then plugs up. The screw dispenser part keeps coming unscrewed. The product is extremely drippy and doesn't stay in the gaps. Had to use a putty knife to try to shove it in but then most of it ends up on the putty knife. If you use this, use industrial strength gloves. I used normal work gloves and it went right through them. I'll be picking it off my skin for a few days. Acetone, paint thinner, and paint stripper didn't remove it from my skin or the putty knife. It's messy to use. I haven't had rodents yet but wanted to plug up possible entrances. Don't think it will work. Too soft and drippy.

Product has alot of downfalls
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.
