Many individuals facing a bedbug problem frequently ask about the duration of these insects’ lives.

A bed bug lives for four to six months. In ideal conditions, a bedbug can live for up to one year.


Egg Stage

The life of a bedbug starts as an egg. An adult female bed bug must have a blood meal to lay eggs.

Bedbug eggs are small, the size of two salt pellets. They are a whitish-cream color and are not easy to spot.

The eggs have a sticky substance covering them. It ensures that the eggs can stick to surfaces before they hatch. The eggs are laid in clusters or singly.

Female bed bugs lay up to 5 eggs daily. They can lay up to 500 eggs in their lifetime. Bedbug eggs hatch in two weeks.

Nymph Stage

As soon as bedbugs are hatched, they get into the nymph stage and start feeding on human blood. Bedbugs pass through four nymph stages before they become adults.

Nymphs look like adult bugs but they are smaller. They are also not yet sexually mature.

The nymphs move through the stages to become an adult in five weeks. Nymphs are yellowish-white while adults are reddish-brown.

Adult Stage

Adult bed bugs need a weekly blood meal, are sexually mature, and bigger than nymphs.

Female adult bed bugs start laying eggs.
