  • Adults are 4-5 mm in length.
  • Bed bugs have an oval, flattened body and are a reddish-brown in colour.
  • The bugs are fairly slow moving and are easily visible to the naked eye.


  • Well fed bed bugs typically live for up to 6 months, although they can survive for 12 months without feeding.
  • A female can lay around 5 eggs per day and a single specimen producing up to 200 eggs during their lifespan. Eggs generally hatch within 2 weeks.
  • Bed bugs search for food by detecting exhaled carbon dioxide and body heat.

  • Normally nocturnal, bed bugs will spend the daytime hiding in small cracks (around the width of a credit card).
  • The bugs will seek harbourage in areas such as the joints of beds, behind skirting boards, behind wallpaper/posters and mattress seams for example.
  • Bed bugs are easily transferable via furniture, bedding, luggage etc meaning that hotels, B&B's and hostels are common sufferers of this pest.


  • Due to their hardy nature and ease of transportation, more than one visit is often needed in order to control bed bugs.
  • Monitoring is an important part of control. The varied use of combined IGR's (insect growth regulator's) and residual insecticide products are required.
