Where can bedbugs reside in a house? - briefly
Bedbugs occupy narrow cracks and crevices near sleeping areas, such as mattress seams, box springs, headboards, bed frames, and nightstands. They also infest furniture, baseboards, electrical outlets, carpet edges, and wall voids throughout the home.
Where can bedbugs reside in a house? - in detail
Bedbugs favor locations that provide direct access to a sleeping host, concealment, and a stable temperature. Within a residential setting they are commonly found in the following areas:
- Mattress and box‑spring seams, tufts, and tags.
- Bed frame joints, headboards, and footboards, especially where fabric or wood gaps exist.
- Upholstered furniture: cushions, springs, and stitching of sofas, chairs, and recliners.
- Cracks and crevices in walls, baseboards, and flooring, including gaps behind crown molding.
- Electrical outlet covers and switch plates where insects can hide behind the device.
- Wall voids and behind wallpaper or paneling, accessed through small openings.
- HVAC ducts and vents that connect rooms and provide a protected pathway.
- Luggage, backpacks, and travel bags placed on or near beds and sofas.
- Curtains, drapes, and blind cords that create dark, undisturbed folds.
- Carpets and rugs, particularly at the edges or under furniture legs.
- Under floorboards, in crawl spaces, and within basement insulation.
- Pet beds, crates, and carriers that are regularly left near sleeping areas.
- Picture frames, mirrors, and decorative objects with hollow backs.
- Bookshelves and stacks of paper where tight binding offers shelter.
These sites share characteristics that support the insect’s life cycle: proximity to human blood meals, protection from light and disturbance, and a microclimate near 20‑30 °C with moderate humidity. Inspection should focus on seams, joints, and any concealed voids where the pest can remain hidden for weeks.
