"It really works" - Sarah Thompson

No more annoying pests! Keep them all away through the power of Ultrasound.

Ultrasound is a sound, or vibration, at an ultra-sonic frequency i.e. a frequency above the hearing range of humans.

The frequencies have been specifically selected so that the sounds are audible to most rodents & the vibrations can be sensed by insects. For these pests, it's like having an alarm going off constantly. It has been shown that pests prefer to nest in areas they are comfortable. This app makes your home very uncomfortable for them.

Through use of this app, most pests leave the area within a few days.

However, if rodents have already built a nest in your house, they are unlikely to desert their young until they are old enough to move. Fortunately, rodents mature quickly and the babies will be fully grown within a month. If you suspect that there is a nest in your house it may be worth using traps as well.

This app has NOT been found to affect cats, dogs, birds, reptiles, amphibians or children.
This app may affect rodent pets such as gerbils, hamsters or chinchillas.
This app will NOT affect any electrical equipment like computers or burglar alarms.

It works

My parents have hamsters or something in their attic, and my room is upstairs so I can hear the noise pretty well. I downloaded this app and literally heard them going crazy running around back and forth. I think the app is so effective that it scared me, because I thought these rodents would break through the wall or something! I turned it off 😂 but then I turned it back on. I’m surprised it works.

Almost perfect

Need the ability to be able to run the app even with the screen off and run in the background. Have to keep the app open always or doesn’t work otherwise.

Are You Kidding Me?

The 1 star reviews are correct. I chose the 7 day trial. This app doesn’t work in the background. You would have to keep your phone on with the app running. I might even deal with that if it worked, but it doesn’t. I was standing right in front of a spider and then later a moth with the app running. Neither of them moved at all. They say you can cancel before being charged by going to settings. It’s not listed in settings. I checked subscriptions and it’s not there. No way to cancel before getting a charge.
