Sonic and Electronic Devices

Sonic and electronic devices do not work.

Sonic, electronic and ultrasonic devices have all been advertised as repelling mosquitoes.  Some devices are available in a bracelet, watch or necklace form for personal protection while others plug into room outlets and claim to eliminate mosquitoes from a larger area.  Manufacturers claim the devices imitate the flight sound of a male mosquito and work because a mated female mosquito would avoid further contact with males. Other devices were supposed to imitate the flight sounds of dragonflies.

A simple test is to find an area of mosquito activity, activate the device for a couple of minutes and then begin to count the mosquitoes that land on an exposed surface (like a leg or arm).  Turn off the device and measure the number of landings on the same surface for the same amount of time.  Repeat this three to five times and you should have a good range of landing catches to compare.  Of course, you can always leave it up to scientists who have consistently found that these devices do not work.
