Bedbugs Can Infest Your Office, Too

THURSDAY, April 19 (HealthDay News) — Add bedbugs to your list
of potential occupational health hazards. A new report reveals nearly half
of the employees of a U.S. government office in Tennessee were bitten by
the blood-thirsty invaders while at work.

A bedbug-detecting German shepherd confirmed the infestation at an
unidentified building in Clarksville, Tenn., last September, and
investigators concluded that at least 35 workers had suffered bites.
Although one woman had bite marks all over her body, the bugs didn’t cause
serious health problems, according to the U.S. Centers for Disease Control
and Prevention report.

Bedbugs can easily expand their territory beyond bedrooms, said Michael
Potter, professor of entomology at the University of Kentucky in
Lexington. “They start in homes and beds, and as people move about, they
get transported into office buildings, schools, libraries, movie theaters,
retail stores, you name it.”

Clarksville, home to about 125,000 people in north Tennessee, is one of
many cities combating bedbugs in nonresidential settings in recent years.
Bedbug infestations have soared since 2000 across the United States,
sending even customers of luxury hotels and upmarket clothing stores into
a panic.

A 2011 survey of U.S. pest control companies found that 38 percent had
responded to infestations at office buildings, up from 17 percent the year
before. Treatments at schools and day-care centers rose to 36 percent from
10 percent, and visits to hospitals jumped from 12 percent of their jobs
to almost one-third.

Bedbugs bite people, often at night, and become engorged with their
blood. The bites cause welts, itching and swelling. However, bedbugs do
not carry disease like some other insects.

The building in question serves children and has 76 employees, said Dr.
Jane Baumblatt, a CDC epidemic intelligence services officer based in
Tennessee. Employees began reporting bites and itching last June, she
said, and the state health department responded.

Theories about the source of the bites included scabies and fleas. But
a German shepherd, one of many dogs around the country trained to detect
bedbugs, found them in cubicles and offices within the building, Baumblatt
said. Also, dermatologists confirmed that the bites were from bedbugs.

Baumblatt interviewed 61 employees and found that 35 had suffered from
bites, often on their legs. “It wasn’t that severe. It was more of a
nuisance than anything,” Baumblatt said.

“The anxiety was that people didn’t know what it was,” she said. “Once
people figured out they were bedbugs, they were relieved.”

The office brought in a pest control company to rid the office of
bedbugs and performed steam cleaning, Baumblatt said.

Potter, the entomologist, said bedbugs prefer beds and stationary
furniture such as couches and recliners because they don’t like disruption
when they feed on people. But they may be transported to offices, day-care
centers or myriad other locations in personal belongings such as
backpacks, briefcases and purses.

Once an office becomes infested, managers may not want to tell workers
in order to avoid a panic, he said. “In the best of all worlds, the office
would inform the employees that some bedbugs have been spotted and they
have a pest control company that’s hopefully involved in dealing with
things,” he said.

However, Potter added, “nothing is easy when it comes to bedbugs.”

The report was scheduled for presentation Tuesday at the CDC’s annual
Epidemic Intelligence Services conference in Atlanta.
