Adult: strongly depressed; oval body; reddish brown; length females: 4mm-8mm; males are slightly smaller. They are normally mahogany red brown but become purple after feeding. They only have small wing buds but have well-developed antennae and compound eyes. The legs are clawed to allow them to climb rough surfaces. Their eggs are slightly curved pearly white and 0.8mm-1.3mm long. They are laid in the hidden areas and cemented to the surface. Three eggs laid per day and approximately 200 over the life. They have an incomplete metamorphosis; they hatch into nymphs after ten to 20 days. Five moults are normal and one blood feed is needed before each moult.
Habitat & Breeding
Bedside furniture, door-casings, under window sills, pictures and posters, under peeling wallpaper, in cracks and crevices in floorboards or skirting boards, in the seams of curtains, and any other similar place that may harbour infestation. Inspect wardrobes, chests of drawers and dressing tables and treat as necessary. Development rate depends on the temperature and food availability: Egg to adult is usually nine to 18 weeks (depending on room temperature). This period is shorter during warmer periods. They have two to four generations per year. If they have fed then they can survive for up to a year at low temperatures, without feeding.
