What should be done if bed bugs do not go away? - briefly
If infestations continue after initial attempts, enlist a licensed exterminator to implement a comprehensive integrated pest‑management strategy, which may involve repeat chemical treatments, heat‑based eradication, and targeted inspections. Concurrently, launder all linens on high heat, seal or discard clutter, and deploy interceptor traps to monitor and confirm elimination.
What should be done if bed bugs do not go away? - in detail
If bed‑bug activity continues after initial attempts, a systematic approach is required.
First, confirm the infestation’s extent. Examine seams, mattress tags, box‑spring corners, bed frames, nightstands, and cracks in walls or flooring. Use a flashlight and a fine‑toothed comb to collect live insects, shed skins, and dark‑red spots. Document findings with photos to track progress.
Second, eliminate all potential harborages. Strip the bed of linens, wash them in hot water (≥ 60 °C) and dry on high heat for at least 30 minutes. Vacuum mattresses, box springs, and surrounding furniture thoroughly, then seal the vacuum bag in a plastic bag and discard it. Encase mattresses and box springs in certified bed‑bug‑proof covers, leaving them on for a minimum of one year.
Third, apply non‑chemical controls. Expose infested items to temperatures above 50 °C or below –17 °C for at least 48 hours; professional heat‑treatment units can raise room temperature to 55‑60 °C for several hours, killing all life stages. Steam cleaners set to ≥ 100 °C can treat upholstered furniture, curtains, and baseboards.
Fourth, introduce targeted insecticides only after non‑chemical measures prove insufficient. Use products labeled for bed‑bug control, following label instructions precisely. Apply residual sprays to cracks, crevices, and behind headboards; use dust formulations in wall voids and under floorboards. Rotate active ingredients to prevent resistance.
Fifth, engage a licensed pest‑management professional. Certified technicians can combine heat, fumigation, or desiccant treatments with monitoring devices (e.g., interceptor traps) to ensure complete eradication. Request a written treatment plan, including follow‑up visits and a guarantee period.
Sixth, monitor post‑treatment. Place interceptor traps beneath each leg of the bed and furniture. Check traps weekly for live insects; any capture indicates residual activity and may require additional treatment. Continue vigilance for at least six months, as bed‑bugs can survive extended periods without feeding.
Finally, implement preventive measures. Reduce clutter, seal cracks in walls and baseboards, keep luggage off the floor when traveling, and inspect second‑hand furniture before bringing it indoors. Regularly wash bedding and vacuum rooms to discourage re‑infestation.
By executing these steps in order—verification, habitat removal, thermal or steam treatment, judicious insecticide use, professional intervention, ongoing monitoring, and preventive practices—persistent bed‑bug problems can be eliminated effectively.
