After hatching the bed bug goes through five nymphal stages that resemble the adult, though they are
smaller in size. A newly hatched nymph is almost colourless. Engorged nymphs are reddish and swollen.
Wild animals, including bats, swallows and house martins may also serve as hosts and may be
responsible for causing infestations in or around buildings.
Bed bugs usually hide in cracks or mattresses during the day and emerge at night to feed. They inject
saliva as they feed. An allergic reaction to the saliva often causes slightly delayed swelling, itching, and
burning which may persist for a week or more.
Female Bed bugs lay eggs throughout their life, generally around 2 to 3 per, each female could produce
around 400 – 500 eggs during her lifetime.
The eggs are deposited all around the environment in which the Bed bug is living.
At temperatures above 21°C (70°F), eggs hatch in 6 to 17 days. At lower temperatures, hatching may
take as long as 28 days.
