Can fleas get from your apartment to another apartment in your building?

Yes, fleas can easily move from one apartment to another in a building, especially if there are shared spaces or if pets or people frequently travel between units. Fleas can hitch a ride on clothing, shoes, or pets, and they can also migrate through cracks and crevices. Once they find a new host, they can quickly establish a population. Regular pest control measures and maintaining cleanliness can help prevent the spread of fleas in multi-unit dwellings.
