No signs of bat droppings since the installation.

Bats were hanging under the eaves. They are not a bad thing, but their droppings were collecting on the patio below. I was about to spend $1000 to have the soffits enclosed, but I wanted to try the Guardian first.

It worked. No signs of bat droppings since the installation. [The Guardian] got rid of the bats and saved me 1000 bucks. I also see that squirrels are taking a different route to collect walnuts on the ground in the same area. Now, if you can design something to repel stink bugs, you will be rich and famous.
