Bed bugs are small, but they're fast movers. If they get into your home, they can quickly spread from room to room, becoming a serious infestation in a matter of weeks.
How do bed bugs spread?
Bed bugs spread in two main ways: reproducing and hitchhiking. How quickly this occurs depends on several factors.
On their own, they move slowly and steadily through a building, traveling along walls, floors, and ceilings to find new hiding spots close to a food source. But the faster, more common route is to catch a ride on people's belongings. Luggage, clothing, used furniture, and bedding are all common carriers.
A single infested item moved from one room, home, or building to another can introduce bed bugs to an entirely new environment. This is how they end up in hotels, offices, and homes that have never had a problem before.
