Within 10 days, the bats were all gone.

A couple of weeks ago, I bought a Guardian because I had hundreds of bats that decided my house was going to be their home. The bats were living under my siding and not in our house, so I mounted the Guardian on the outside of our home. Within 10 days, the bats were all gone. Even our neighbors can't believe I got rid of them that easy and that fast. I still have it attached to the house, but have it operating on battery power. I just wanted to let you know how pleased I am with the Guardian; it was well worth the money.
