  • Adults grow to be 5 mm long
  • White, oblong, and about 1 mm-long eggs

What is the size of a bed bug?

As adults, bed bugs only grow to be about 5 mm long. This is best visualized as the size of an apple seed, or about 1/4 to 3/16 of an inch. Bed bugs grow a big bigger after a meal. After feeding, the bed bug body will appear slightly longer, more cylindrical, and more red. Adult bed bugs are visible to the human eye even though they tend to hide out of view.

Bed bug stages of life

After eggs hatch, bed bugs go through five larvae (or nymph) stages. Bed bugs lay their eggs in mattresses, furniture, wall cracks, baseboards, and floorboards. These eggs are white, oblong, and only about 1 mm long. Nymphs look like miniature versions of the adult bed bug. After blood meals, the bed bug nymph will shed its exoskeleton several times before reaching its final stage of life.
