- Eggs
- Nymphs
-
Adults
-
Eggs:
Bed bug eggs measure about 1 millimeter in length and are pearly white in color. They have a smooth, oval shape. Bed bug eggs are typically deposited in clusters, often in hidden crevices near bedding or furniture. The average female bed bug lays between 1 to 5 eggs daily, leading to a rapid increase in population. According to a study by T. A. McCoy (2021), an infestation can grow exponentially if not detected early. -
Nymphs:
Nymphs are immature bed bugs that undergo five growth stages before reaching adulthood. They start life as tiny, translucent insects about 1.5 millimeters in length. As they molt, they darken in color and grow larger. The nymphs vary from nearly invisible to light brown as they approach adulthood. Nymphs require a blood meal after each molt to continue growing. Nymph stages can be confused with tiny ticks or other pests, which can complicate detection. -
Adults:
Adult bed bugs are about 4 to 5 millimeters long and have a flat, oval body. They are reddish-brown in color and increase in size after feeding. Adults possess two compound eyes and slender, segmented antennae. Their bodies become swollen after a blood meal, which alters their appearance. Adult bed bugs are often mistaken for apple seeds due to their shape and color. According to the CDC, identifying adults accurately is crucial for effective pest control.
How Can I Recognize Adult Bed Bugs?
Adult bed bugs can be recognized by their oval shape, reddish-brown color, size of approximately 4 to 5 millimeters, and distinctive and unpleasant odor. Understanding these characteristics can help in identifying an infestation.
