Bed Bug Babies and Nymphs: Pictures and Information

Knowing what bed bug babies (commonly known as nymphs) look like, and their lifecycle, is an important step in understanding and identifying a bed bug infestation in your home. Once you confirm an infestation you will be able to take appropriate actions to treat the problem.

Appearance of nymphs

Bed bug nymphs look similar to adult bed bugs: oval, flattened (when unfed), with six legs, and a ribbed back. However, unlike their adult counterparts, nymphs are much smaller (about the size of a poppy seed), and their color can vary from translucent to pale white.

After a nymph has had a blood meal, they will appear to be bright red to the eye, and be more readily visible.

Although they are smaller than adults, they are still visible to the naked eye, and hide in the same places you’d expect to find adults.


Nymphs go through five stages before becoming adults. They require at least one blood meal to molt, shedding their exoskeleton (shell), before passing through the first stage. At every stage they darken in color, and become larger, until they more closely resemble an adult.

Each immature stage of their lifecycle takes approximately one week. That means that after approximately after 5 weeks they will reach full adulthood. Each female adult bed bug can lay approximately 500 eggs over their life time.

Exterminating nymphs

Killing the nymphs before they have time to mature and reproduce is extremely important to curbing the bed bug population in your home. Active bed bugs live approximately 9 months and lay 500 eggs, so getting treatment as soon as possible is imperative.

There are plenty of at-home products to help capture and reduce the population, and it is always recommended to seek the help of an exterminator at the first sign of an infestation.
