Does anyone know of a way to tell the difference between flea bites and bed bug bites?
Bed bug bites generally happen multiple times in the same area, so you may see up to three bumps right next to each other. Thats a pretty big give away.
Bed bugs only come out at night, so you should only be alarmed if you get bitten during the night.
