What to do when exterminating bedbugs? - briefly
Identify and isolate infested zones, then apply a professional‑grade insecticide according to label directions. Follow with high‑temperature laundering of linens, thorough vacuuming of seams, and a repeat treatment after 7‑10 days to interrupt the life cycle.
What to do when exterminating bedbugs? - in detail
Effective elimination of Cimex lectularius requires a systematic approach that combines thorough inspection, preparation, treatment, and post‑treatment monitoring.
Initial inspection should identify all harborages. Examine seams of mattresses, box springs, headboards, bed frames, baseboards, electrical outlets, and cracks in walls. Use a flashlight and a fine‑toothed comb to collect live specimens or shed skins for confirmation.
Preparation involves reducing clutter, laundering all bedding, curtains, and removable fabrics at ≥ 60 °C for 30 minutes, then drying on high heat. Vacuum carpets, upholstery, and flooring, discarding the vacuum bag or emptying the canister into a sealed plastic bag. Seal infested items in polyethylene bags for at least two weeks to starve hidden bugs.
Treatment options fall into chemical and non‑chemical categories:
-
Chemical interventions
- Apply EPA‑registered pyrethroid or neonicotinoid aerosols to cracks, crevices, and seams, following label directions for dosage and safety.
- Use residual spray formulations on baseboards and furniture legs to maintain activity for several weeks.
- For resistant populations, consider professional application of desiccant powders (e.g., silica gel) or carbon dioxide‑based foggers.
-
Heat treatment
- Raise room temperature to 50 °C–55 °C for a minimum of 90 minutes, ensuring uniform heat distribution with calibrated thermometers.
- Portable heat chambers can treat infested luggage, clothing, or small furniture items.
-
Cold treatment
- Expose items to ≤ ‑20 °C for at least 48 hours; this method is effective for sealed containers and clothing.
-
Physical removal
After treatment, conduct weekly inspections for four weeks. Use sticky traps or passive monitors placed near suspected harborages. Record findings to assess residual populations. If live bugs persist, repeat the chosen treatment or integrate an alternative method to address potential resistance.
Preventive measures include maintaining a clutter‑free environment, sealing cracks in walls and flooring, and inspecting secondhand furniture before introduction into living spaces. Regularly wash bedding on high heat and periodically rotate mattress positions to discourage re‑infestation.
