After waking up one night in sheets teeming with tiny bugs, Josh Benton couldn’t sleep for months and kept a flashlight and can of Raid with him in bed.
“We were afraid to even tell people about it at first,” Benton said of the bedbugs in his home. “It feels like maybe some way your living is encouraging this, that you’re living in a bad neighborhood or have a dirty apartment.”
Absent from the United States for so long that some thought they were a myth, bedbugs are back. Entomologists and pest control professionals are reporting a dramatic increase in infestations throughout the country, and no one knows exactly why.
“It’s no secret that bedbugs are making a comeback,” said Dan Suiter, an associate professor of entomology at the University of Georgia.
Before World War II, bedbug infestations were common in the U.S., but they were virtually eradicated through improvements in hygiene and the widespread use of DDT in the 1940s and 1950s.
Bedbugs are tiny brownish, flattened insects that feed exclusively on the blood of animals and humans. Their bites may cause itchy red welts or swelling.
Unlike mosquitoes, though, they are not known to transmit blood-borne diseases from one victim to another. They are extremely resilient and very difficult to exterminate. Experts say bedbugs are not necessarily an indicator of unsanitary conditions.
In the past four years, reports of bedbugs have significantly increased in U.S. cities, from New York to Honolulu, especially in hotels, hospitals and college dormitories — all places with high resident turnover.
The National Pest Management Association, which represents many of the country’s pest control companies, says the number of bedbug reports have increased fivefold in four years.
The Atlanta branch of pest-control firm Terminix saw no cases of bedbugs in 2004 and only three or four last year. But in the first six months of this year, they’ve had 23 new cases, said Clint Briscoe, a spokesman.
Experts are not entirely sure what has caused the marked increase. Some speculate that increased international travel and immigration may be partially to blame.
Hitching a ride
The tiny bugs may be hitching a ride in the luggage or clothing of travelers. This could explain the high concentration of the pests in cities like Atlanta and New York, which attract a lot of international traffic.
Another factor is a change in pest control practices. Companies are spraying more responsibly now, Suiter said. Instead of indiscriminately saturating the perimeter of all rooms, they often use more conservative measures and do large-scale spray treatments only when there’s an infestation. As a result of consumer demand, less toxic chemicals are also being used.
“The bottom line is it may be a convergence of all those factors, but none of that really explains the rapid increase in recent years,” said Michael Potter, a professor and urban entomologist at the University of Kentucky.
Experts agree that the public needs to be educated about bedbugs — on the symptoms and how to prevent them.
“A lot of people, including some physicians, don’t even think they’re real,” Potter said. As a result people may go months before realizing the source of their discomfort.
In Hawaii, where tourism is a major industry, state lawmakers passed a resolution for a prevention campaign after infestations at some hotels damaged their reputations and annoyed travelers. Similarly, legislation for a bedbug task force has been proposed by New York City Councilwoman Gail Brewer.
For Benton, a 31-year-old graduate student, the bedbugs sparked a seven-month battle that included bug bombs and the tossing out of his and his fiancee’s bedroom furniture.
They gave up and moved out of their apartment in New York and eventually moved back to their native Memphis, Tenn. Benton said the bugs essentially drove them out of New York because they couldn’t sleep knowing the bugs may be anywhere.
“The main part of it is psychological trauma that they create because of the idea that they are feeding on you at night,” Benton said. “It’s still hard to talk about if it’s anywhere near bedtime.”
