Even staying at a pricey Hilton Hotel and sleeping on luxury linens doesn't guarantee freedom from being bitten by bed bugs. Soprano Alison Trainer slept at the Phoenix Hilton Suites between Nov. 20 and Nov. 26, and said she was bitten 150 times and traumatized by the bugs who shared her bed.

Trainer has sued Hilton Hotels Corp. for $6 million claiming it was a "horrific" experience that resulted in a fear of sleeping in a bed, caused her to lose weight and affected her physical appearance.

"She looks like a piece of wood that has been attacked by termites," Trainer's attorney, Kenneth J. Glassman, told the AP.

Bed bug infestations in hotels and homes have increased in recent years. Earlier this year a woman filed a $20 million suit against a hotel in the Catskills where she claimed she received more than 500 bed bug bites, USA Today News reported earlier this year.

The cause of increasing bed bug infestations in the U.S. is believed to be linked to increased foreign travel. Many nations are infested with bed bugs and travelers bring them home, according to USA Today news.
