Bed bugs are from the insect family Cimidae and they survive by consuming the blood of warm blooded animals, including humans. They prefer to live in mattresses and sofas and are mostly active at night, which is the source of their name. They are attracted to warmth and their saliva contains anesthetics and anticoagulants, which allows them to feed on their host without the host noticing their presence.

Bed bug bites lead to a raised welt or a red bump. This welt often results in severe itching.
Cause
These bumps are caused by an allergic reaction to the bed bugs' saliva.
Time frame
The bumps caused by bed bug bites typically take up to nine days to become visible.
Bite patterns
Bed bug bites tend to occur in bunches, possibly as a result of the bug becoming disturbed while eating and needing to move slightly.
Variabilty of rash
Different people have different levels of allergic reactions to bed bug bites, with some people being barely affected and others developing an extensive rash that can also lead to symptoms such as nausea and a headache.
