Electronic mosquito repellent devices don't work. These small units sit on a table or are worn on the wrist or clipped to a belt or keychain. Manufacturers claim the ultrasonic sounds they emit repel mosquitoes and other bugs. However, scientific studies have repeatedly shown that electronic mosquito repellers do not prevent mosquitoes from biting

The classic bug zapper is also an ineffective type of electronic mosquito repellent. Research shows the most effective units are high-tech traps that use propane or CO2 plus other attractants. The high-end mosquito units, such as Dragonfly mosquito traps and SkeeterVac, have several features that make them worth the price tag. By incorporating several types of attractants, they have a greater effect on the mosquitoes in your yard than other equipment.

A small heat pad generates the heat in the trap. Spectrum light bulbs and/or UV light bulbs produce the light attractant. If sound is incorporated in the trap, it is designed to mimic the noise female mosquitoes make when feeding (females bite; males don't). The trap then kills the mosquitoes with a fan that blows insects into a catch tray where they are zapped. Some trays are filled with water, used as a moisture attractant. Many of these traps work not only on mosquitoes, but also on other biting insects such as no-see-ums and biting flies.

Once the biting pest finds its way into the machine, it is then electrocuted, chopped, or drowned, depending on which unit you purchase. Either way, the trap will kill a lot of mosquitoes when placed where mosquitoes are found. These traps are designed to confuse meal-seeking insects so they find and enter the trap before they find you. For the best effect, place the trap around the perimeter of your property where mosquitoes may enter. Keep it away from areas where people gather, ideally 30-40 feet away from them but still close to the mosquitoes' location.
