The range of different types of electronic pest control devices is seemingly endless, with everything from electric fences to electronic motion detectors and animal repellents. While electronic fences and other deterrents can pose health risks, it is the emitting type of devices that come most often into question. These devices work in one of two ways: They emit an odor that is unpleasant to insects or animals while pleasant to humans, and the other which emits ultrasonic sound waves that deter or repel pests.
Odor-Emitting Electronic Pest Control
Electronic pest control devices that use odor to either repel, confuse or detect pests have health implications. The chemicals used, especially the ones used as repellent, can contain carcinogens or other airborne pollutants. There are chances of accidental skin contact by someone who has allergies to one or more of the chemical components. There haven't been any conclusive studies about the possible effects of any of these chemicals on the environment.
Sound-Emitting Pest Control
Sound-emitting pest control devices emit a high-frequency, highly directional squeal that can easily cause distress to pets. They only work in areas where the sound is not blocked and some are strong enough to affect not only your area but that of neighbors. The sounds are inaudible to humans, except in rare cases, but are clear when heard by microphones and recording devices. They can cause distortion over telephone lines. Some customers with hearing aids have complained that these devices cause distortion. It is also possible that these devices can confuse some burglar-alarm systems, sending false signals.
Precautions
All in all, these devices are safe. Like any type of equipment, electronic pest control devices should be used under proper conditions. If you have someone at home with allergies, check the chemicals used. If you have people at home with hearing aids or pacemakers, check with both your doctor and the manufacturer for any possible problems. Read the manual thoroughly and make sure the settings are for your property so as not to cause problems with your neighbors.
