Ohio is among the most bed-bug-infested states. Correct identification is key to effective management.Graphic comparing the appearance and size of various insects that can be misidentified as bed bugs.

Bed Bug Habits

  • Prefer to feed at night on human blood.
  • Hide during the day in cracks, crevices, and dark places.
  • Cannot fly but walks very fast.
  • Can survive several months without feeding if a host is absent.

In-Home Prevention and Maintenance

  • Use special bed bug-proof covers (encasements) on mattresses and box springs, leaving them on for at least a year to prevent bugs from entering or escaping.
  • Reduce items under the bed and in the bedroom to remove potential hiding spots.
  • Vacuum frequently, focusing on mattresses, box springs, carpets, and baseboards, then immediately seal and dispose of the vacuum bag.
  • Wash and dry bedding and clothing on high heat to kill bugs and eggs.
  • Repair peeling wallpaper, seal cracks in plaster, and caulk gaps in baseboards or furniture.Graphic showing the various growth stages of bed bugs.

Preventing Introduction from Outside

  • Inspect hotel rooms for bed bugs (check behind headboards). Keep luggage on metal racks, in the bathroom, or in sealed plastic bags rather than on the bed or floor.
  • Thoroughly inspect used furniture, clothes, and mattresses for signs of bugs (fecal spots, casings) before bringing them home.
  • Immediately wash and dry clothes from trips on high heat and inspect suitcases thoroughly.
  • If you have guests, encourage them to keep luggage off carpets and beds, or provide a designated spot.

Monitoring and Early Detection

  • Place bed bug interceptors (e.g., ClimbUP) under the legs of beds and upholstered furniture to catch bugs trying to climb up or down.
  • Regularly inspect your mattress and furniture, especially after traveling or having guests.
  • If living in shared housing, promptly report any signs of bed bugs to management, as they can travel between units.

Living in Shared Housing?

  • Bed bugs spread through walls, pipes, and shared hallways in multi-unit buildings. An infestation in one unit may spread to others through no fault of the residents.
  • Promptly report any signs to building management.
  • If management is unresponsive, contact your local health department
  • In Ohio, tenants have the right to a pest-free unit.
