Size and color
Bed bugs are oval, wingless insects that are rusty brown in colour and around 4 to 5 mm long when fully grown.
Heavy bed bug infestations are often associated with a distinctive sickly sweet smell and blood spotting may be evident on mattresses and/or bedding and nearby furniture.
Bed bugs will hide (and lay eggs) in a variety of household objects close to where humans sleep such as mattresses, bed frames, furniture, behind skirting boards, loose wallpaper and floorboards, and in cracks and crevices of walls.
They are blood feeding insects that prefer to bite humans but will also feed on other warm blooded animals. As their name suggests, bed bugs generally feed at night when people are in bed.
