What’s the Life Cycle of a Bed Bug?

Bed bugs life cycle Bedbugs, just as you’d expect, start as eggs laid by a female who is in the right stage for breeding. Typically, a female bedbug can lay between 1-5 eggs per day; this can equate to hundreds of bedbug eggs laid in one female’s lifetime. The conditions have to be right however for a female to lay her eggs.

Bed Bug Breeding Conditions

Female bed bugs will only lay eggs in the right environmental factors. Temperature, location, and food source availability (read: blood) all need to be ideal before a female decides to lay eggs. If your home is between 75-80 degrees fahrenheit and there are tight fibers or crevices where blood is accessible, it might present the prefect bedbug breeding ground.

About 2 weeks after a bedbug egg is laid by the female, it will hatch into a young bedbug, or nymphs. Nymphs appear similar to adults in appearance, but are smaller and unable to breed. Bedbug nymphs need to progress through five “molting stages” to become mature bedbugs. One molting stage is complete when a nymph feeds on blood. The time to maturity on average is about five weeks in an ideal bedbug environment.

After a bed bug has matured, each one will feed weekly. Imagine the mess it could make and the havoc it could wreak if you have dozens or hundreds of bed bugs in your home! A mature bedbug’s life span is typically between four to six months, but can be up to one year in some cases. With such a long lifespan, and the ability for one female to lay hundreds of eggs in that lifetime, it’s easy to see how an infestation can spin out of control.
