Bed Bugs

What is a bed bug?

The bed bug, Cimex lectularius, is a small but visible insect about the size of an apple seed that exclusively feeds on blood. The adult is approximately ΒΌ inch in length, brownish in color with an oval, flattened body. Eggs hatch within 10 days and mature into adults within 2 to 4 months. They pass through 5 nymphal instars before reaching adulthood, taking blood meals during each stage (see image to the right).

Bed bugs can live for over a year and, under optimal conditions, adults may feed every few days. Bed bugs will feed on a variety of animals, but prefer humans. They are most active at night often biting people while they sleep, but may feed at any time.
