Definition

• Bites from bed bugs

Symptoms

• Usually cause itchy, red bumps in a group or line
• Often they look like a hive or mosquito bite
• Bite may have a red dot (puncture) in the center. This is where the bed bug bit through the skin.
• Occasionally, a small blister can occur in the center
• Bites are usually on exposed skin (arms, legs and face)
• Bites are usually first noted in the morning

Diagnosis

• Live bed bugs hide and are not usually seen. Close inspection of the mattress may find some.
• They are 1/4 inch (6 mm), flat, oval shaped, reddish-brown bugs.
• Suspect bed bugs if over 3 red bumps in a row are on exposed skin. The bumps or bites are very itchy.
• Bed bug waste (feces) are found on bedding or mattress seams. It looks like dark brown flecks or coffee grounds.
• A blood stain on the sheet may sometimes be found. This is from a bug smashed after feeding.

Cause

• Bed bugs are small visible blood-sucking bugs. They are about ¼ inch (6 mm) in length.
• During the day, bed bugs hide in the corners of mattresses. They may also be found in bed crevices, floors, and walls.
• At night, the bed bugs come out of hiding. They feed on humans for about 5 minutes.

Prevention of Getting Bed Bugs

• Over half of bed bug infestations within homes start after recent travel.
• Avoid hotels and hostels where bed bugs have been reported. (see bedbugregistry.com)
• When you check into a hotel room, look for signs of bed bugs. Look for flecks of their waste (like coffee grounds) in the bedding and mattress. If present, ask for another room.
• Keep your luggage and clothing on a luggage rack off the floor.
• When you return from a trip, place all travel clothing into the clothes dryer. Run the dryer for 20 minutes. (Reason: The heat will kill any bed bugs or their eggs that are present). One pregnant bed bug can spread bed bugs to an entire house.
