Types of Electronic Pest Repellers
Pest repellers use one or more of the following technologies: ultrasonic, electromagnetic, ionic, sonic scare and visual scare.
Some are designed for small indoor areas while others are for use over large areas outdoors. The most popular of these are electronic pest repellers that are used in homes which are purchased and installed by the home owner. Many units are also installed by pest control professionals particularly outdoors to control birds and large animals.
They range in price from less than $10 for the home units to close to $1000 for the large area outdoor types. It is important to make sure that the device you select is appropriate for the pests that you are dealing with. Also be aware that while there are many good products out there, some don’t work very well. Ask questions, read reviews and get a money back guarantee.
Ultrasonic
Ultrasonic technology creates sound that is beyond the range of humans and most pets but is very uncomfortable for pests causing them to flee the area.
Some units have a fixed frequency of maybe 30 to 35 kilohertz while other units allow for the adjustment of the frequency and loudness to target a particular type of pest. Some of the units designed for outdoor use also include audible sound.
Be aware that ultrasonic units work best when the sound waves can bounce off walls, floors, ceilings and hard furniture. Carpet, drapes and upholstered furniture reduce the loudness of the sound. While some indoor units cover 3000-5000 square feet several units are required throughout the house since ultrasonic sound waves travel in a straight line and the sound level gets lower after numerous bounces.
Outdoor units may have multiple speakers and cover very large areas.
Electromagnetic
An electromagnetic pest repeller plugs into an AC power outlet and injects electromagnetic waves on the electrical wiring throughout a building. Pests are very sensitive to changes in electromagnetic energy. The frequency of the waves is tuned to provide discomfort to the pests and drives them out.
It gets to the pests hiding within walls, attics, basements and areas that the ultrasonic pest repellers can’t reach.
Ionic
Ionic technology has been used for years in air purifiers. It creates negative ions which act to destroy harmful airborne pollutants, including bacteria and dust mites.
This technology is now being used in electronic pest repellers. Negative ions which are produced by the repeller causes pests to leave the area. The ions also clean the air of food odors which is also a deterrent.
Sonic (Audible Sound) Scare
There are many types of sonic devices which make various sounds to scare pests away.
There are electronic units that generate sound waves into tunnels of burrowing animals such as moles and gophers.
Different units are designed to protect different size areas, from the typical yard all the way up to 8 acres. They can be programmed to emit various sound combinations. The key here is to have random sounds so the pests don’t get used to them. Some have proximity detectors that sense when an animal is near and activate the sound.
There are special units for repelling birds. These are usually bird specific. They work by having actual bird distress cries recorded on a microchip. When the birds hear the sound they think that members of their flock are in trouble so they leave the area.
Visual Scare
One of the most common visual electronic pest repellers is a strobe light which displays different colors of light. Some display ultra-violet (UV) light.
A very novel type of devices is an electronic scarecrow which has a proximity sensor that detects heat and movement. When it detects an animal it opens a valve which releases a blast of water similar to a yard sprinkler for a few seconds. The visual movement along with the sound causes the unwelcome pest to be on his way.
Conclusion
Among the entomologist community, the use of radio frequency to control, insects have been met with great enthusiasm. They can be used as an alternative to many chemical insecticides used nowadays that may not only make the pest develop resistance but also pollute the environment and even have negative consequences on non target species like bees.
Researchers at Kansas State University have concluded that ultrasounds do repel some insects pests and even interfere with their mating activities. Despite the fact that their results are not consistent, they pointed out that anything that can interfere with the reproductive cycle of insects could be of great importance in reducing and mitigating the damage to crops.
