Bed bugs are slow crawlers and walkers, making their spread quiet and silent! They can spread from one infested unit to another rather easily by hitching a ride on backpacks, purses, suitcases, and other items, which can easily introduce them to other parts of an apartment building. If you see the signs of bed bugs in your apartment, it’s crucial to tell your landlord as soon as possible. Doing so can help stop the bed bugs from spreading into other parts of the apartment building.
