The bed-bug is a wingless ectoparasite with an oval body. The body is flattened unless it has taken a blood feed, after which the abdomen will be distended as it taken on a blood meal up to 7 times its own bodyweight. Colour ranges from brown to mahogany depending on when the last blood meal was taken.
The bed-bug inhabits houses worldwide. More commonly associated with hotels and hostel accommodation where the adults infest cracks, crevices, furniture and bedding.
Bed-bugs will usually feed at night while the host is sleeping, bite marks visible on body parts exposed to bedding or furniture. Bed-bug harbourages produce a distinct musty smell which is an accumulation of faeces and scenting.
