Bed bugs can result in a number of health effects including skin rashes, psychological effects and allergic symptoms.[5] Bed bug bites may lead to skin changes ranging from non visible to prominent blisters.[1] Symptoms may take between minutes to days to appear.[2] Itchiness is common, while some may feel tired or have a fever.[2] Typically uncovered areas of the body are affected.[2] Classically three bites occur in a row.[2] Bed bugs bites are not known to transmit any infectious disease.[5][7]


Bedbug bites typically are stealthy and not felt by the host. This is because they inject a numbing substance into the skin along with an anticoagulant agent to prevent blood from clotting at the feeding site. Itchy, red bites on the skin may be the first sign you've been bitten. Bites are most common on the arms and shoulders, and the bites often occur in straight rows, as pictured here.
Unlike those of other insects, bed bug bites may sometimesĀ appear in tight lines of multiple, small, red marks where multiple bed bugs have fed along an exposed area. Bed bug bites can cause itchiness. Initially, a victim may detect a slight burning sensation. The burning area then develops red bumps, known as papules or wheals (rash). In extreme cases, bites may swell dramatically or turn into blister-like skin inflammations.
