About Bed Bugs

Bed bugs bite you and feed on your blood. You may have no reaction to the bites, or you may have small marks or itching. Severe allergic reactions are rare. Bed bugs don't transmit or spread diseases.

Adult bed bugs are brown, 1/4 to 3/8 inch long, and have a flat, oval-shaped body. Young bed bugs (called nymphs) are smaller and lighter in color. Bed bugs hide in a variety of places around the bed. They might also hide in the seams of chairs and couches, between cushions, and in the folds of curtains. They come out to feed about every five to ten days. But they can survive over a year without feeding.

To prevent bed bugs in your home:

  • Check secondhand furniture for any signs of bed bugs before bringing it home
  • Use a protective cover that encases mattresses and box springs. Check it regularly for holes.
  • Reduce clutter in your home so they have fewer places to hide
  • Unpack directly into your washing machine after a trip and check your luggage carefully. When staying in hotels, put your suitcases on luggage racks instead of the floor. Check the mattress and headboard for signs of bed bugs.

To get rid of bed bugs:

  • Wash and dry bedding and clothing at high temperatures
  • Use mattress, box spring, and pillow encasements to trap bed bugs and help detect infestations
  • Use pesticides if needed

When to speak to someone. Reading about a topic cannot tell you whether it applies to you. Speak to a doctor or pharmacist if symptoms are severe, sudden, getting worse, or simply not going away — and seek emergency care immediately for chest pain, breathing difficulty, sudden weakness or confusion, or a serious allergic reaction.

Research on Bed Bugs

1 study isregistered for this condition on ClinicalTrials.gov, the U.S. National Library of Medicine's public registry. A selection is below — the links go straight to the registry entry, not to a summary of ours.

What a registered study does and does not mean. Registration means a study exists and has been declared publicly. It says nothing about whether the treatment being tested works, is safe, or is available to you. Many studies find no benefit — that is what research is for. Never seek out an experimental treatment on the strength of a registry entry alone.
