Just saying the words "bed bugs" is usually enough to make most people visibly shudder, haunted by visions of recurring infestations and expensive fumigation. So we talked to Brittany Campbell, Ph.D., staff entomologist for the National Pest Management Association—and probably one of the few people in the world who seems genuinely excited to talk about bed bugs—to demystify the pests.
Bed bugs have been around since our ancestors lived in caves. The bed bugs lived in the caves too, feeding on humans and later bats after people found other places to live.

Bed bugs usually come out at night for a blood meal. However, they are opportunistic insects and can take a blood meal during the day, especially in heavily-infested areas. Bed bugs usually require 5-10 minutes to engorge with blood.
