A bed bug starts out life as an egg. Female bed bugs will lay eggs in batches of 10-15 and as many as 5 or 6 in a single day. Bed bug eggs are roughly 1mm long and are pearly white in color. Bed bug eggs can often be found near where the adult and young bed bugs hide during the day.
The adult bed bug life span usually last 6-12 months. How to Check for Bed Bugs 1) When staying at a hotel, check the piping of the mattress and the box spring for tiny black marks.
Female bed bugs lay about five eggs daily throughout their adult lives in a sheltered location (mattress seams, crevices in box springs, spaces under baseboards, etc). Eggs hatch in about 4-12 days into first instar nymphs which must take a blood meal before molting to the next stage.
Bed bugs have five immature nymph life stages and a final sexually mature adult stage. They shed their skins through ecdysis at each stage, discarding their outer exoskeleton. Newly hatched nymphs are translucent, lighter in color, and become browner as they moult and reach maturity.
Bed bugs have quite a long life cycle and lifespan in comparison to similar blood-sucking parasites. This prolonged life makes them especially difficult to eradicate completely. It takes a bed bug around five weeks to go through each of its baby to adolescent nymph stages and reach sexual maturity.
The life cycle of a bed bug is shown in the photograph below. During its lifetime, a bed bug will go through the following stages (Starting from the top left, moving counterclockwise): Eggs (1mm). 1 st stage nymph (1.5 mm).
