briideaBat Exclusion Device, Reusable One Way Bat Door Get Rid of Bats in Your Home, Attic

It is unfortunate that they call it a valve. There is no valve. It is just a tube that is too small for bats to fly into with their wings spread. They can crawl down it and jump out. Once they open their wings to fly, they can't get back inside. The instructions were rather vague. It appears that you just need it extended away from the house so there is nothing near the opening for the bats to climb onto and get back inside. Also, point is a little downward so that rain cannot enter the tube.

Was very skeptical, it worked perfect! Well worth the money!!

I am going to send it back. Can’t figure out how to use it and not sure if all the parts were included. There is no diagram or clear directions on how to set it up. There is no website listed to go to for help either.

It provided a way for the bats to leave. Way over priced for what it is. Now that I have seen it, it's not difficult to make out of things from the store.

It is deceiving because it is essentially just a tube! Stretch out the tube, keep it straight, pointing down the little rats will exit and they cannot fly back up!

The media could not be loaded. I used spray foam to seal the house and the cone in place. 30-40 bats 🦇 are gone and now looking for a new home.

This is supposed to go in a vent so the bats can go out and not get back in. It is an inappropriate size.

As advertised, and once installed correctly, bats can get out, but can’t get back in. Local wildlife regulations require a bat exclusion device to be in place for at least four nights before you can seal up their entry point. We followed that regulation and haven’t seen any bats since. Hope they found a new home.
