Ultrasonic Bedbug Devices Debunked as Useless
Prevent Bedbug Infestations
These devices retail for $20 to $40. “I would take that money and use it to launder all clothes and put them in a sealed tote, because this would protect them more than [ultrasonic] detection,” Jones says.
Drying bedding and clothing at high temperatures for 20 minutes kills bedbugs, she says.
What else can you do?
“Bedbugs are a labor-intensive and time-intensive insect to deal with,” Jones says. If you suspect you have bedbugs, call a professional and they can tell you if it is a look-alike or a real bedbug.
Dini Miller, PhD, is an associate professor of urban entomology at Virginia Tech in Blacksburg, Va. “If these worked, we wouldn’t have a bedbug problem in the U.S.,” she says.
Unfortunately, “we don’t have a great answer for bedbugs right now,” she says. “We are pretty good at taking care of 12 bedbugs, but where things get tough is when you have 1,200.”
Heat and insecticides are the best available answers now, but they are not fail-safe.
The best way not to get a bedbug infestation is to keep the critters out of your home.
“It doesn’t matter if you notice a few when travelling or get bites,” Miller says. “You just don’t want them to come home with you.” Check yourself and any belongings before you come home.
