We used that foam stuff too when we moved in and noticed lots of holes in the ground around the foundation. But they chew it. As a matter of fact, I found a spot that we sprayed that foam into from the outside, chewed to pieces the other day! Made me so mad. I'm going to open the outlet covers in our bedroom and try that mint oil trick and see if that helps. We have more than enough outlets to try it in, can't hurt.I have read to open an outlet and stuff into the wall some cotton soaks in mint oil. Not sure if that will work in your walls but that's what I've read.
I went around in our basement and used that foam stuff to fill in all the cracks I could find and still we get mice in the attic. I hate meeces to pieces!
Question...Where would one buy Mint Oil?
Nevermind, DH is going to make some at work and bring it home.
