Makes the room unappealing
It works by putting out ultrasound at 25 to 45 kHz that rats and mice find unpleasant, so they leave rather than settle. Nothing is killed and nothing needs clearing up.
Plug it in and leave it
It runs from a normal wall socket around the clock, with no batteries to swap and no bait to refresh. Once it is in, it looks after itself.
Placement is the whole trick
Ultrasound does not pass through walls or furniture, so use one unit per room and leave the front clear. Coverage reaches up to 3,200 square feet in an open space.

Frequently Asked Questions
How does it actually work?
It emits ultrasound between 25 and 45 kHz, a range rodents find disturbing and people do not hear. The space stops feeling safe to them, so they move on without traps or chemicals.
How much area does one unit cover?
Up to 3,200 square feet in open space. Because sound does not travel through walls or large furniture, plan on one unit per room and keep the front of it unobstructed.
Is it safe around cats and dogs?
It is chemical free and designed for homes with cats and dogs. Small pets such as hamsters, guinea pigs and rabbits are sensitive to ultrasound, so do not run it in a room where they live.
Where should I plug it in?
In a socket with a clear line into the room, not behind a sofa or a cabinet. Moving it to a different socket now and then also helps, since animals can get used to a fixed source.
Is there anything to maintain?
Nothing. There is no bait to replace, no battery to change and nothing to empty. Unplug it before wiping it down and that is the full extent of the upkeep.
