Sound instead of chemicals
It works by making a space unappealing rather than by poisoning anything, using frequencies from 20 to 55 kHz. Nothing is sprayed and nothing is left behind.
Safe around family and pets
There are no toxins and no odor, so it can sit in a garden or a room where children and animals spend their time.
Covers a real area
One unit reaches across 80 to 120 square meters and draws only six watts, so leaving it running through a season costs very little.

Frequently Asked Questions
How does it actually work?
It emits ultrasonic frequencies between 20 and 55 kHz that make an area uncomfortable for pests, so they move on. Nothing is killed and nothing is sprayed.
Is it safe around pets and children?
Yes. It uses no toxins, no bait and no odor, which is exactly why it can sit in a family garden or a room where a dog sleeps.
How large an area does one cover?
Between 80 and 120 square meters. Open, unobstructed space gives the best results, so placement does more for the outcome than anything else.
How much power does it use?
Six watts. That is low enough to leave running continuously through a whole season without a noticeable difference to your bill.
Where should I place it?
Somewhere with clear line of sight across the area you want covered and out of reach of small children. Moving it occasionally through the season keeps it working well.
