The first sign most people have of a bed bug infestation is bite marks on their skin. However, many other insect bites and spider bites look the same, so this isn’t definitive. You cannot feel a bed bug bite. Some people do not react to bed bug bites, while others get huge welts after the bites. It is the itching and welts that bother people. Unfortunately, you can’t tell whether a bed bug has bitten you or a flea has. The bites look the same. Bed bugs defecate on the bedding before and during feeding. Bed bug excrement looks like small dark brown or black dots that tend to bleed around the edges. You can also find these in large numbers where bed bugs congregate. You may find bloodstains on your bedding and nightclothes. These stains represent bed bugs that you crush as you roll over them at night. Bed bugs are nocturnal, so they are not as visible during the day. Bed bug colonies hide in cracks and along seams then. They can get into any crack that is the thickness of a credit card, where they spend most of their time. If you see live bed bugs, then you have a problem. However, many people misidentify other insects and mites as bed bugs, so make sure you have actual bed bugs before you start treating your house.
