Where do apartment bedbugs come from and where do they live? - briefly

Bedbugs usually enter an apartment through infested furniture, luggage, or by migrating from adjacent units, and they hide in narrow crevices such as mattress seams, box‑spring folds, baseboards, furniture joints, and wall voids. Their preferred habitats provide darkness, proximity to human hosts, and easy access to blood meals.

Where do apartment bedbugs come from and where do they live? - in detail

Bedbugs enter multi‑unit dwellings through several well‑documented pathways. Human movement is the primary vector: infested luggage, clothing, or personal items carried from hotels, dormitories, or other residences introduce the insects. Secondhand furniture, especially upholstered pieces, often harbors eggs and nymphs; even items that appear clean can conceal hidden stages. Professional pest‑control equipment, such as vacuums or tools that have not been sterilized after use in another building, may also transport live bugs. Finally, structural connections between units—shared walls, ventilation ducts, electrical conduits, and plumbing shafts—allow insects to migrate across adjacent apartments without direct contact.

Within an apartment, bedbugs concentrate in locations that provide shelter, proximity to hosts, and stable microclimates. Typical sites include:

  • Mattress seams, box‑spring corners, and bed frames where blood meals are readily available.
  • Furniture joints, headboards, and upholstered cushions that offer crevices for hiding.
  • Wall voids, baseboard gaps, and behind picture frames where temperature remains constant.
  • Electrical outlets, switch plates, and appliance gaps that conceal small colonies.
  • Luggage racks, closets, and shoe shelves that receive infested personal belongings.

Bedbugs prefer temperatures between 24 °C and 30 °C and relative humidity of 60–80 %. These conditions are often met in sleeping areas, but the insects will occupy any cryptic space that meets their thermal requirements. Their ability to survive several months without feeding enables them to persist in rarely used rooms, such as storage closets or vacant apartments, awaiting the return of a host. Understanding these entry routes and preferred habitats is essential for targeted inspection and effective eradication.
