Signs of bed bugs are different from signs of fleas in the bed. Bed bugs typically leave rust colored markings on bed sheets. The bed bugs also tend to discard their exoskeletons as they molt from one life cycle stage to another. Fleas on the other hand leave black colored debris. You might also see blood stains in your bedding. If needed, use flea traps under or near your bed.
Barring a rare allergic reaction, flea and bed bug bites are more often an annoyance than anything else, and bed bugs specifically are not known to carry any diseases harmful to humans. Flea bites are slightly more worrisome, however, since fleas are known carriers of typhoid, tapeworms, and plague, although all three of these are rare in the U.S.
Bed bug poop or bed bug droppings is a telltale sign of bed bug activity. They can often be the first indication of an infestation. Bed bugs feed on blood, preferably human blood as it tends to provide the best nutrition.
