No end to bedbug infestations

Summer may be over, but bedbugs don't seem to have ended their vacation in New York.

Their latest hideout is the 95,000-square-foot Niketown store in the heart of Midtown Manhattan. Nike told CNN the company closed the store because of the presence of bedbugs. A sign posted over the weekend said the story is "temporarily closed until further notice," according to CNN affiliate WABC.

In a major space like that, seven to 10 days of treatment are recommended to eradicate the vermin, says New York Magazine.

The pest control company Terminix has rated New York the number one bed bug city, according to WABC.

Elsewhere, bedbugs are going back to school: at Lehigh University, four dorm rooms were found to have bedbugs, CNN affiliate WFMZ reported Friday. Those rooms are being treated, Lehigh officials told WFMZ.

Hotel owners and guests alike are freaked out by the possibility of bedbugs. The horror stories are building up on websites such as The Bed Bug Registry and BedBugReports.com.

The bugs leave behind itchy bite marks on the skin, and some people have allergies to them. Bedbugs tend to live within 8 feet of where humans sleep, according to the Centers for Disease Control and Prevention.

That means that if you're a hotel guest, bedbugs can get in your suitcases and come home with you, says Howard Russell, entomologist with diagnostic services at Michigan State University. You might want to consider keeping your luggage in garbage bags to prevent bedbugs from becoming stowaways.

It's not as easy as just waiting for the critters to die, since bedbugs can live for one year without eating.
