Why would you want to repel bats? They eat their body weight in mosquitos.
I wonder if it will work in white tailed deer, which eat their body weight in vegetables out of my garden.
It doesn’t list deer as one of the pests it repels, but I’ll ask the vendor just to be sure.
In answer to the question about repelling whitetail deer the vendor says:
“Yes it should repel deer. It has adjustable eagle, dog, or gunshot sounds.”
