| Adult Bed Bug - 1/4" | Bed Bug Eggs |
Adults are small, brownish insects, just under a 1/4” long and are relatively flat. They are nearly as wide as they are long, and oval in shape. Immature bed bugs (nymphs) resemble the adults, but are much smaller and lighter in color. Newly hatched nymphs are translucent and are no bigger than a pinhead (1 mm). After feeding on a blood meal the immature bed bugs may appear bright red in color. Bed bugs lack wings and therefore they do not fly, but they are capable of moving swiftly on both horizontal and vertical surfaces. The eggs are very small (approximately 1mm), whitish, and very difficult to see on most surfaces without magnification (individual eggs are about the size of a dust speck).
