How Big Are Bed bugs?

Bed bug

Have you ever wondered “how big are bed bugs?” You’ve probably heard they’re challenging to spot, which is why you have to look for other signs, like blood marks (from you!) and feces.

How big are bed bugs?

They’re tiny. So tiny, in fact, they are most often measured in millimeters instead of inches. Bed bugs molt several times throughout their life, started at the egg stage, then nymph stage and working (growing) their way up to adulthood.


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.


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.
