Bed Bugs

Bed Bugs
Bed bugs, Climax Lectularius
Bed bugs adults are reddish brown, oval, flattened insects from 4-5 mm long and 1.5-3 mm wide before feeding. Engorged adults tend to be swollen and dull red. The eggs are white, oval, about 1 mm long and covered in a sticky film which allows them to adhere to surfaces. A newly hatched nymph is almost colourless whereas engorged nymphs are reddish and swollen.

Although humans are the preferred host, bed bugs feed on many warm-bloded animals. Bed bugs usually hide in cracks or mattresses during the day and at night to feed. They inject saliva as they feed and allergic reaction to this substance often causes delayed swelling, itching and burning.

Under good conditions, each female lays 200-500 eggs and they hatch between 7-17 days. They
can survive up to 2 months without food, but are able to live more than a year without feeding
if conditions are favourable.
