The short answer is YES, sonic Pest Chasers work to repel rodents and NO, sonic Pest Chasers do not work to repel insects. In fact, the US Government has ruled that ultra-sonic product devices are NOT proven to repel insects.
Ultrasound repels rodents
by subjecting them to auditory stress. In terms of humans, it is like a continuous scratching of a chalkboard with your finger nails. Very simply, ultrasound hurts rodent’s ears.
Sonic pest chasing devices use a classic animal behavior modification technique. Unlike traps and poisons, ultrasound does not kill rodents. The Pest Chasing units have the ability to provide long-term reductions in rodent populations by creating a “rodent-unfriendly” environment that discourages rodent infestations.
Unfortunately, if you have pet rodents of any kind – you can not use pest chasers in the same room as your pet! Rodent pets include mice, rats, hamsters, guinea pigs, ferrets, and squirrels. Never install an ultrasonic pest chasing device in a room that is inhabited by rodent pets. The sound will cause your pet severe auditory stress. The ultra sonic devices can’t go through walls .. but better save than sorry. Keep your pets a couple rooms away!
Sonic pest chasers will not work effectively outside – although some manufacturers have developed squirrel chasers
that work on this theory that can keep squirrels away from bird feeders.
The PestChaser emits high frequency ultrasonic sound waves between 32 and 62 kHz to create an acoustically hostile environment that repels rodents from sound-protected rooms. It’s kinder than traps, safer than poisons, and completely inaudible to people and non-rodent pets. Unlike traps and poisons, the PestChaser minimizes human contact with disease-bearing rodents (no dead rodents to dispose of).
It is very important to note when thinking of purchasing an ultrasonic pest chaser the following SCIENTIFIC facts:
- Ultrasonic sound waves decrease in intensity by the square of the distance, the same as for light.
- Ultrasonic waves cannot penetrate objects
- Ultrasonic waves leave a shadow of unprotected areas behind obstructions such as posts, desks and boxes.
- Ultrasonic waves travel in a direct line form the device and cannot go around corners.
- The ultrasonic waves cannot penetrate walls.
Given this information, How can an ultrasonic device situated in a room repel rodents inside a wall? NO
Can an ultrasonic device situated in one room repel rodents in other rooms? NO
Therefore .. you need to get a device per room.
