Bed Bugs

  • Bed bugs are about the size of an apple seed and are flat before feeding.
  • They typically feed at night while a host is asleep, but may feed during the day if very hungry.
  • Bed bugs feed by inserting a long, sharp proboscis into the skin and drawing blood.
  • Their hosts include humans as well as other mammals and birds.
  • When not feeding, their mouthpart (feeding tube) is tucked underneath their body.
  • After feeding, a bed bug can increase up to 50% in length and up to 200% in weight.
  • Bed bugs reproduce through a process called “traumatic insemination.”
  • Females can lay hundreds of eggs over their lifetime and may live a year or longer.
  • After hatching, bed bugs go through five nymph stages before becoming adults.
