What Are Bed Bugs

Bed bugs are small, oval-shaped insects that are about the size of an apple seed. They have six legs and two antennae. Adult bed bugs are reddish-brown, but they can also appear to be tan, yellow-brown, or even white after molting.

The Life Cycle of Bed Bugs

Bed bugs go through several stages of development before reaching adulthood. The stages are as follows:

  • Egg: Bed bug eggs are about the size of a pinhead and are white. They are typically laid in cracks and crevices and take about 6-10 days to hatch.
  • Nymph: After hatching, bed bugs go through several nymphal stages. Nymphs are smaller than adults and are yellowish-white in color. They molt, or shed their skin, after each stage and require a blood meal to progress to the next stage.
  • Adult: Bed bugs reach adulthood after five nymphal stages. Adult bed bugs are about 5-7mm in length and have a flat, oval-shaped body. They are reddish-brown and feed on blood.


The certain color of a bed bug depends on if it’s fed or unfed. Unfed bed bugs are mahogany to brown colored. When they are fed well they become reddish-brown.


Baby bed bugs are called nymphs and they are almost colorless when they first hatched. Then they keep their translucent or whitish-yellow unless they are fed.  They become brownish when they grow up.



Bed bugs are oval-shaped creatures. However, they have flatted and oval-shaped bodies, their body will change after they are recently fed. Their body will become like a balloon and elongate after they are fed and they will turn to a deep reddish-brown color.
