All About Bed Bug Nymphs

Like all pest infestations, the sooner you identify an issue, the better. For bed bugs, that means finding the pests before they have the chance to mature. Bed bugs start as eggs and are called larvae once they hatch. Today, we’re taking a closer look at larvae, starting with what baby bed bugs look like.

What Do Baby Bed Bugs Look Like?


To understand the size of baby bed bugs, it’s helpful to know the size of eggs and adult bed bugs.

  • Eggs: Bedbugs are an astonishing 0.09 inches, which is 2.5 millimeters. Good luck seeing them with a naked eye! And if you want to get rid of a bedbug infestation, these tiny, tiny eggs are what you need to attack.
  • Nymphs: The nymphs are about the size of a grain of pepper—yes, that small! It’s challenging to give an exact size for nymphs because they are anywhere between the egg size and adult size because they molt multiple times.
  • Adult bed bugs: Adult bed bugs are twice as big as the eggs, making it up to 0.18 inches, or 4.5 millimeters. If you’re trying to wrap your head around that size, consider that 0.1 inch is just a little thicker than a quarter. Basically, they are the size of an apple seed.


Bed bug nymphs are usually whitish-yellow in color. If they haven’t fed recently, they may be nearly invisible, and you won’t be able to spot them. As they mature, they turn brown.

Are Bed Bug Nymphs Harmful?

Yes. Just like adults, bed bug nymphs can bite. If you notice bites on your exposed extremities but can’t find adult bed bugs, consider taking a closer look for nymphs.
