What size are bed bug eggs?

Bed bug eggs are approximately one millimeter or the size of a pinhead. They can grow up to five times that size once adulthood is reached.

Bed bug eggs have a pearl-white tone and are virtually invisible to the naked eye due to their tiny size and ability to blend in with bedding and mattresses. Once they reach five days old, bed bug eggs may be identified by a single eye mark.

In adulthood, bedbugs resemble apple seeds in appearance and size. Bed bugs have five different stages of life, with approximately .5 millimeter of growth during each cycle. They can ultimately reach five to seven millimeters in length.
