Tomcat Rodent Block Expanding Foam Barrier keeps mice out.

Review: 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.
Review: I used this product and no longer have mice racing through my apartment. I was told the product needs to be reapplied every six months to keep the mice out.

## 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!
