Bedbugs (Cimex lectularius) are small, oval insects. Bedbugs are 5-7 mm in length and do not fly. Bedbugs can live anywhere in the home and are most active at night. For example, they may live in cracks in furniture or in any type of textile, including upholstered furniture. Bedbug infestations are most common in beds, including the mattress, box springs, and bed frames.
Signs and symptoms of bedbug bites include
- small, flat, or raised bumps on the skin,
- redness,
- swelling, and
- itching.
They are typically not painful. The face, neck, hands, and arms are common areas for bedbug bites because these areas are most likely to be exposed while sleeping.
Cause of bedbug bites
Bedbugs feed by sucking blood from humans or other warm-blooded animals.
