A bed bug has 6 legs. Its antennae point forward and are about half as long as the body—not longer. Its head is broadly attached to its body and it has no wings. Color: A “drop of blood with legs” is probably a recently fed bed bug. It will be red, plump, and oval. After it digests its meal, it’ll be mahogany-colored, round, and flat. Unfed nymphs are tan. Eggs are oval, white, and stick to whatever they’re laid on. Size: You can see the adults—they’re about 1/4” long. Eggs and just-hatched nymphs are tiny: 1/16” (1mm) long—the size of the “R” in “LIBERTY” on a penny. They’ll plump up after feeding—just like a mosquito.
