It Sort of Works

I have a 26' x 50' empty barn with a loft over half of it that a colony of bats (about 40 of them?) have been living in the sandwiched roof of it for several years now. The interior peak of the roof is about 25 feet high and the loft floor is about 10 feet above the main floor. So I set this product up with the recommended settings and plugged it into an extension cord and laid it flat on it's back on the loft floor in about the middle of the barn and pointed the speakers towards the peak of the roof. I could immediately hear the bats chattering so I thought this is going to work great. The next day I returned and some of the bats, maybe 10 of them, had moved to the outside of the barn under the eaves. So I stayed until dusk to see if they still flew out of the roof and on the end of the roof where the loft is they did not but on the other end where the height of the peak of the roof is 25' they did (about 10 or so I think). So I'm thinking I either need another one of these for that end of the barn despite the claim that this product covers 5,000 sf (which it does not) or this product just isn't strong enough to transmit a loud enough sound 25' away to drive the bats out. So I think this product would work in small, open attics. And I'm still going to wait and see for another week or 2 before I decide if I'm keeping it or not but I won't be buying another one for the other end of the barn. I'll just have to find something a little bit better.
