How to get rid of bedbugs that have appeared in an apartment? - briefly
Locate and seal all harborages, then apply a professional heat‑treatment or approved insecticide to eradicate the insects. Afterward, wash all linens at high temperature, vacuum thoroughly, and monitor for any signs of reinfestation.
How to get rid of bedbugs that have appeared in an apartment? - in detail
A confirmed infestation requires immediate, systematic action. Begin by isolating the problem area: encase mattresses, box springs, and pillows in zippered, bed‑bug‑proof covers and keep them sealed for at least 12 months. Wash all bedding, curtains, and removable fabrics in hot water (≥ 60 °C) and dry on the highest heat setting for a minimum of 30 minutes; heat kills all life stages.
Next, reduce hiding places. Declutter rooms, vacuum floors, carpets, and upholstery thoroughly, discarding the vacuum bag or cleaning the canister in hot, soapy water. Focus on seams, folds, and crevices where insects shelter. After vacuuming, steam‑treat surfaces using a portable steamer that reaches ≥ 100 °C; steam penetrates fabrics and cracks, eliminating eggs and nymphs.
Apply chemical controls only after non‑chemical measures. Use a registered, residual insecticide labeled for bed‑bug control on cracks, baseboards, bed frames, and furniture legs. Follow label directions precisely, applying a thin, even coating to avoid over‑application. For hard‑to‑reach voids, consider an aerosol dust (e.g., silica‑based) that remains effective for several months.
Monitor progress with passive traps. Place interceptors under each leg of the bed and furniture; replace them weekly and record captures. Continue the cycle of vacuuming, steaming, and targeted insecticide applications for at least three weeks, as bed‑bugs can hatch from eggs after two weeks.
If the population persists after two treatment cycles, enlist a licensed pest‑management professional. Professionals can deploy heat‑treatment chambers or fogging equipment that achieve temperatures and coverage beyond DIY capabilities. Document all actions, dates, and observations to guide further interventions and to provide evidence should you need to involve landlords or housing authorities.
