Bed Bug Identification & Control

Identifying bed bugs

  • Bed bug adults are dorsally flat, ¼-inch long, and tan to brownish in color
  • Bed bug nymphs look similar to adults only smaller. 
  • Bed bugs do not jump, fly or hop –  they only walk.
  • Carpet beetles, fleas, lice, roaches, ticks, bat bugs and even seeds and lint have all been mistaken for bed bugs

Signs of bed bugs

  • Small reddish brown fecal spots 
  • Molted skins 
  • Tiny, white eggs 
  • Red, itchy bite marks on skin

Preventing bed bugs

Everyday 

  • Regularly inspect bed sheets, mattresses and areas where pets sleep.  
  • Thoroughly inspect any new furniture before bringing it into your home
  • When shopping, inspect clothing carefully before purchasing and immediately wash new clothing in hot water.
  • Regularly inspect children’s backpacks and jackets when they return home from school. 

While traveling

  • When checking into a hotel room, place suitcases directly into the bathtub and thoroughly check underneath mattresses, behind headboards and around baseboards.
  • Vacuum suitcases and wash all clothes in hot water  after returning from any vacation. 

Bed bug control options

Nonchemical

  • Heat infested articles/areas to more than 120 degrees fahrenheit for at least 90 minutes. 
  • Place bedding and clothing in dryer at high temperatures for at least 30 minutes. 
  • Cold treatments (below 0 degrees fahrenheit for at least 4 days) can eliminate some infestations. 
  • Use mattress, box spring and pillow encasements to trap beg bugs and help detect infestations. 
  • Use monitoring devices to ensure bed bugs have been  eradicated and to detect new infestations.  

Chemical

  • Always read and follow all directions on the pesticide product label. 
  • Use a comprehensive strategy for controlling bed bugs –  pesticides should be one part of a multi-part IPM plan. 
  • You may want to consult a pest control professional to inspect your home and treat any infestations
  • For suggested pesticide products consult the “Bed Bug Product Search Tool” available through EPA’s website.
