Bat Repellent for Attic, Outdoors & Indoors - Cleanrth CB006 Advanced Ultrasonic Bat Repelling System (2-Pack)

very effective. Bats disappeared after running this for a day. ‘Nuff said.

It worked within 2 days it’s awesome

We own a large 30,000 building that we live in the upstairs. We were getting a lot of bats inside weekly. For the better part of 2 months we were experiencing basically a bat invasion lol. We tried mothballs shiny objects everything you can imagine that you google on the Internet. We put up bat netting and nothing worked until we purchased two of these units. After the units were installed almost instantly. There was a significant decrease in activity. And within three weeks, we had one bat show up. It has now been four months and not a single bat. I walk around the building and I used to find evidence of bat droppings here or there, but there has been nothing in that amount of time. We are finally free of bats! Thank you.

Cats freaked out as soon as this got plugged in. It may work, but if you have cats, I wouldn’t risk the purchase.

We had a couple bats hanging out in our cottage while we weren’t there. I bought two of these along with some aroma packs. The bats have left and we have not seen any in over 2 months.

Got the bats out so I could seal crack

I was skeptical about this product, but it worked immediately. I previously had bats in our attic so was concerned when I found droppings outside under our back porch. I bought two of these and they worked fast. No droppings the next day or since. Thinking of buying more to put in the attic just in case.

Not sure these are working as well as their black ones they carry.I've not noticed a change at all.Easy plug in, no noise level. Priced very high in my opinion especially if they don't work!
