Bed Bug Bites or Mosquito Bites?
The first and biggest warning signs are bites. These look like mosquito bites, but usually come in clusters of at least three. They especially tend to affect exposed areas while you sleep, like arms, neck, face, and shoulders, and they tend to come in rows along the line of the comforter or sheet. If you find suspicious bites, conduct a basic inspection the way you would at a hotel.
