With spring break coming up, travelers may want to make sure they don't pick up the souvenir no one plans to take home - bedbugs. Bedbug cases have been increasing dramatically over the past three or four years, said Dawn Gouge, entomologist and associate professor at the University of Arizona. "Pretty much everywhere where anyone goes on vacation is where you'll find bedbugs," said Gouge, noting that even travelers who stay at high-end resorts can be exposed to the parasites.
