briidea - Ultrasonic bat repeller, bat repeller system, will make bats flee, safe for humans and pets

Instalé este dispositivo para murciélagos y funcionó de inmediato.

Seems to be working. Less evidence of the bats. Evidence was typically poop on the ground nearby. Placed in the garage and used at lower setting still worked for bats in space in the front of the garage. Would recommed for others to try.

El producto no sirve, literalmente lo puse a 5 metros de los murciélagos y a estos no les importa, de igual forma lo desarme y tiene un mecanismo muy sensillo, no vale su precio

This product does not work at all. I’ve had it for about three months and it has made absolutely no difference. The bats are still around just like before. I was really hopeful, but it’s been a complete waste of money. Don’t bother buying this.

We'd been dealing with bats creeping into the living areas through the drop ceiling with increasing regularity for about a month. Driving them out of a window or open door was time-consuming, if kind of enjoyable (for me, at least, having no real fear of the beasts). Eventually, I purchased this item, plugged it in and adjusted settings per instructions. I was able to barely hear the sound of it, almost like a very mild tinnitus, but it wasn't bothersome to myself or those who live with me. For the first couple of weeks after plugging it in (we didn't actually screw it into the wall, as that was against the lease, just plugged it in in a central part of the house and left it in the corner on the wood floor), we continued having bats getting into our space nightly—if anything, it was more of them; however, patience paid off and by the middle of the third week, we neither saw nor heard them anymore. Used to hear scritching in the drop ceilings even before we ever saw them at all—I always assumed it was mice or a squirrel, but was disabused when they invaded. No scritching since. Fairly confident they have moved out entirely, so I'm keeping it running to avoid getting the issue again.
