Cimex Lectularius

Appearance

  • Bed bugs are around 5 to 6mm long before a blood meal extending to about 7mm when fully engorged.
  • Oval and flattened from back to underside with thick, well-developed legs. Bed bugs do not have wings.
  • Their mouths are pointed for piercing and sucking.
  • Adult bed bugs are rusty red-brown in color.
  • Eggs are whitish cream, getting darker as they hatch to larvae.
  • Their shed skins are lighter brown and look like flaky exoskeletons.

Lifecycle

  • Bed bugs lay 200 – 500 eggs over a 2 month period in batches of 10 to 50.
  • The adult female must have a blood meal before egg-laying.
  • The eggs are usually laid in crack and crevices and can be attached to items of furniture or fittings in clusters by a transparent substance.
  • There are 7 stages to the lifecycle from egg to fully grown adult which can be from 45 days but may be up to a year.
  • The typical lifespan of a bed bug is about 50 days to over a year depending on favorable conditions.
  • They can survive for weeks to months without feeding.

Habits

  • Bedbugs feed on human blood and are attracted to body heat and CO2 from sleeping humans.
  • They inject an anaesthetic when they pierce the skin, so the bite can go unnoticed at first.
  • They are found in cracks and crevices, headboards, behind peeling wallpaper, broken plaster, light switches, under carpets and skirting boards etc. so they are near to people for feeding.
  • Bed bugs usually visit their host for a blood feed just before dawn. When alarmed they move quickly and emit an odor.
