No longer have mice!
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.

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.

Messy
Sticky and messy and does not work. Drips out of the mouse hole and doesn't expand quick enough. I would not purchase this item again. It does not seal up a mouse hole. Just made a mess.

Messy as hell
This was probably the messiest product I’ve ever bought plus it being obviously very toxic according to the label you gotta hurry up and get acetone to clean it off right away should it contact your skin.Hopefully, you have it on hand to clean it off your fingers,because it’s super sticky. What I read said to use it with steel wool together to block mice and let me tell you that was really difficult to work with together with this product. I don’t think I would go this route again.
