Identifying a bed bug:
Adult bed bugs are generally flattened and reddish brown in color. They resemble apple seeds in appearance and size. Newly hatched nymphs look very much like adults. Although they are almost colorless, they gain their reddish brown color as they mature. The adult bed bug may lay up to 5 eggs daily. These eggs are almost impossible for humans to see with the naked eye, and resemble a flake of dust on a dark surface.
