Bed bugs are brownish in color with flattened-oval bodies. Adults are about 3/4" in length while nymphs are smaller and lighter in color. Adult females can lay about 5 eggs per day and about 500 in a lifetime. The eggs are whitish in color and are hard to see without magnification. These eggs will turn into nymphs and before long you may have a full blown infestation on your hands. Bed bugs often are mistaken for ticks, cockroaches, or bat bugs
