We don’t want to freak you out, but bed bugs actually feed on human blood in order to survive. As if that wasn’t bad enough already, they don’t even ask permission – how rude. Basically, they’re vampires. Actually, no. They’re worse than vampires. At least vampires have to be invited in first, whereas bed bugs just barge right in and start feeding on any human in sight. I know this sounds bad, but I promise there’s good news. Bed bugs are surprisingly easy to detect, and Jim Dill is here to show us exactly how to avoid an encounter the next time we visit a hotel.
