The 2010 North American Bed Bug Summit is under way in Rosemont, Illinois, where some 400 exterminators, entomologists, researchers and hoteliers have gathered to discuss bloodsucking insects with experts. Bed bug hysteria has officially reached its apex.

About 200 people were turned away from the sold out event, according to the Chicago Tribune. Besides hosting intense discussions on bed bugs, the Hyatt hotel also has at least 50 vendors showing off everything from mattress encasements to carbon dioxide Cryonite freezer blaster things. Scooby the bed bug-sniffing dog was even there. Watch!
