Bed bugs are masters of concealment. Even without a blood meal, their slim, flat bodies allow them to fit into the smallest of spaces and stay there for extended periods of time. Bed bugs are typically transported from location to location as people travel.
Bed bugs hide in the seams and folds of luggage, overnight bags, folded clothes, bedding, and furniture, among other places. Most people are unaware that they are transporting stow-away bed bugs from location to location, infecting areas as they go.
