Your worst fears about those insect bites on your leg have been confirmed—your home has bedbugs. Don’t panic. There are ways of dealing with these blood-sucking pests. Unfortunately, they do not include gadgets that promise to get rid of bed bugs using ultrasonic frequencies.

Little is known about bedbug sensitivity to sound. But Northern Arizona University researchers report that commercial devices producing ultrasound do not repel bedbugs. In lab tests, the insects proved quite indifferent to sonic assaults. Their report is in the Journal of Economic Entomology. [K. M. Yturralde and  R. W. Hofstetter,
Efficacy of Commercially Available Ultrasonic Pest Repellent Devices to Affect Behavior of Bed Bugs (Hemiptera: Cimicidae)]

It’s also unproven whether similar ultrasonic devices sold to get rid of mosquitoes, cockroaches, fleas or ants work as advertised.

What is the best way to get rid of bedbugs? In a Scientific American article published earlier this year, University of Kentucky entomologist Kenneth Haynes noted that a combination of approaches—including heat treatment and a drying agent—works best.

Haynes recommends calling in trained professionals rather than taking on the problem yourself. So sleep tight. And, ya know…

    Bed bugs can live for over a year, even trapped in a bag around the bed. They are pernicious, they can travel between apartments and homes, and can be picked up pretty much anywhere: buses, theaters, restaurants, even from someone's bag sitting next to yours. The can also live in many places other than the bed; headboards, pictures, nightstands, light switch plates, clothes . . . . . they can even fit in the cracks of floorboards and at the base of walls.

    I've had them a few times. I use a powder around the edge of my matress, made from diatomacious earth and pyrethrins. The DE slices up their shells and they dehydrate, and pyrethrins paralyze insects. They have to crawl through it to feed (gross, but it's the best way to not only kill them, but prevent them from moving, too, as they would if the can't get to food.)

    Horrid things; the only saving grace is that they do not carry any disease.

    A product I buy labeled "Chemfree" which contains diatomaceous earth, states on the label to kill small ants, earwigs, silverfish, etc. and also bedbugs. Don't know about the bedbugs because I have not had to deal with them (yet) but works very well on everything else.

    I am an exterminator and I know bed bugs are nightmare to some people. Sometimes my customers so irritated by Bed Bugs that they offer me triple my price to get emergency and fast removal of bed bugs. I WAS WONDERING if I would get some device somewhere which can repel bed bugs. Technology is advancing and I am sure near in future, pest control would be replaced with Devices that can help to prevent pest. Bed Bug Problems are common in our city. Such Devices or alternate option to Pest Control can gain acceptance.
