What should be used to treat against bedbugs? - briefly
Effective control combines EPA‑registered insecticide sprays targeting bedbug nervous systems with heat treatment that raises infested spaces to at least 50 °C for 30 minutes. Professional assessment and post‑treatment inspections confirm eradication.
What should be used to treat against bedbugs? - in detail
Effective control of Cimex lectularius requires a multi‑modal approach that combines chemical, thermal, and mechanical tactics. Reliance on a single method rarely eliminates all life stages.

Synthetic insecticides approved for indoor use
• Pyrethroid‑based sprays (e.g., permethrin, deltamethrin) – target nervous system, fast knock‑down effect.
• Neonicotinoid formulations (e.g., imidacloprid) – useful against pyrethroid‑resistant populations.
• Insect growth regulators (e.g., hydroprene) – inhibit molting, reduce future generations.
• Desiccant powders such as diatomaceous earth or silica gel – abrade exoskeleton, cause dehydration. -
Physical and thermal methods
• Heat treatment at 45‑50 °C for a minimum of 90 minutes – penetrates fabrics, furniture, and wall voids, resulting in 100 % mortality.
• Steam application (≥100 °C) on mattresses, seams, and upholstered surfaces – destroys eggs and nymphs on contact.
• Freezing at –18 °C for at least four days – effective for infested clothing and small items.
• Vacuuming with HEPA‑rated filters – removes visible insects and eggs, reduces population density. -
Mechanical barriers and sanitation
• Mattress and box‑spring encasements with zippered closures – isolate existing bugs, prevent new infestations.
• Sealant of cracks, crevices, and baseboard gaps – eliminates refuge sites.
• Regular laundering of bedding at ≥60 °C – eliminates eggs and nymphs.
• Removal of clutter – reduces hiding places and facilitates treatment penetration.
Professional pest‑management services provide expertise in assessing resistance patterns, applying residual insecticides, and executing whole‑room heat treatments. Safety considerations include ventilation during chemical application, adherence to label instructions, and protective equipment for applicators.
« Integrated pest management, when properly executed, yields the highest probability of long‑term eradication ». Combining the listed strategies, monitoring with interceptors, and maintaining rigorous housekeeping practices constitute the most reliable protocol for eliminating bedbugs.
