## What is Ultrasonic Anti Pest & Insect?

"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.
