Basics in Inspection and Detection

Live bed bugs

  • Bed bugs are visible in their adult form.  They are approximately the size of a pencil eraser, red to brown in color, flat and oval in shape
  • .Blood Stains from crushed bugs or Rusty (sometimes dark) spots of excrement on sheets and mattresses and walls.
  • Fecal spots, eggshells and shed skin may be found near their hiding places.
  • An offensive, sweet, musty odor from bed bug scent glands may be detected when infestations are severe.

Eggs / Molts

  • It takes approximately 1 month for the life cycle to go from egg to adult, under ideal conditions.  The nymph will molt  5 times in that month.

 

Fecal Matter

  •   Fecal spotting tends to appear as not as red blood but instead as dark/black      stains or smears from the digested blood that is excreted.

Blood  Spots

  • The bed bug is unable to digest all of its blood meal and therefore excretes a portion of the undigested blood on the areas where it crawls.  Another event that occurs is that as they are feeding the individual will move around in the bed and squeeze the bed bug between their body and the bedding.

Bites

  •  A bed bug pierces the skin of its host with two hollow feeding tubes. With one tube it injects its saliva, which contains anticoagulants and anesthetics, while with the other it withdraws the blood of its host. After feeding for about five minutes, the bug returns to its hiding place.
