What attracts bedbugs in an apartment? - briefly

Bedbugs are attracted to human occupants by the carbon dioxide, body heat, and scent they release, and they thrive in cluttered spaces that provide sheltered harborages. They commonly appear in homes with frequent guest turnover or used furniture, which raise the likelihood of introduced infestations.

What attracts bedbugs in an apartment? - in detail

Bed bugs locate a residence primarily through the presence of a reliable blood source, suitable hiding places, and conditions that facilitate their movement and reproduction.

A reliable blood source is provided by humans and, occasionally, pets. Warmth from the body, carbon dioxide exhaled during respiration, and the scent of skin secretions act as strong cues. The insects can detect these signals from several meters away, guiding them toward occupied rooms.

Suitable refuges include:

  • Mattress seams, box‑spring cavities, and bed frames where the insects can remain concealed during daylight.
  • Upholstered furniture, especially sofas and recliners, that contain dense fabric folds.
  • Wall cracks, baseboard gaps, and electrical outlet covers that offer dark, undisturbed spaces.
  • Luggage, backpacks, and clothing left on the floor or stored in closets, which can transport insects between rooms or apartments.

Environmental factors that enhance survivability:

  • Temperatures between 70 °F and 90 °F (21 °C–32 °C) accelerate development and egg laying.
  • Relative humidity above 50 % supports egg viability and prevents desiccation.
  • Cluttered spaces increase the number of potential harborage sites and impede detection.

Human behaviors that increase risk:

  • Frequent travel without inspecting or treating luggage upon return.
  • Purchasing second‑hand furniture without thorough examination.
  • Delaying removal of infested items or neglecting regular cleaning of bedding and upholstery.

These elements collectively draw bed bugs into a dwelling, sustain their population, and promote spread throughout the apartment.
