The bats have not returned. Hooray!

I simply had to write you. While I purchased the Guardian for helping with some voracious squirrels, just this past week some bats got into the walls where squirrels had chewed a wooden panel below the soffit. I reset the Guardian to annoy the bats.

After one very noisy night (they were unhappy — LOL), they exited the building and have not returned! Hooray! I will keep the unit plugged in and working until the entrance is caulked. Thanks for a great product!
