Bed bug life cycle

The life cycle of bed bugs is one of the main reasons why Cimex lectularius has been so successful infesting man-made properties in recent decades. It's helpful to have a solid understanding of the bed bug lifecycle so you know what you're up against when an infestation threatens your home or business. 

The problem with bed bugs isn't that they can live for an extraordinary long time but that they are prolific breeders. In their lifetime, a single female bed bug will lay upwards of 540 eggs. Bed bugs will lay eggs daily. Once a bed bug population has infested a room with right living conditions, it won't take long for the infestation to grow to be severe. 

If you have an ongoing bed bug problem in your property, don't wait for it to get worse. Call the professionals at Ehrlich at 1-800-837-5520 or contact us online to schedule a free pest inspection. 

The bed bug life cycle: (left to right) eggs, bed bug nymph, mature bed bug nymph, adult bed bug

Bed bug eggs

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. 

Young bed bugs

A bed bug starts out as an egg that hatches into a nymph. Before each life stage the bed bug molts, leaving shed skins behind. Discarded bed bug skins are often one of the first signs of an infestation. Once the bed bug hatches, it seeks out a host to get a blood meal.

A bed bug goes through several nymph stages before reaching adulthood. When bed bugs are progressing through the nymph stages, they are very small and hard to see. When bed bugs reach adulthood, they are about the size of an apple seed.

Full adult bed bugs

An adult bed bug grows to 1/4 inch in width and is typically reddish-brown in color, especially after feeding. Bed bugs do not fly but they do crawl quickly and are highly proficient at latching on to luggage or clothes. 

An adult bed bug can last without feeding for as long as 1 year. Bed bugs have not been found to spread any diseases. However, some people can develop secondary infections to bed bug bites
