Bedbugs have appeared at home; what should be done? - briefly
Inspect bedding, furniture seams, and wall cracks; wash contaminated textiles at ≥60 °C and dry on high heat, then vacuum thoroughly and seal the vacuum bag; apply a registered insecticide according to label directions or enlist a licensed pest‑control service; place interceptor traps around beds and re‑inspect weekly for at least 30 days.
Bedbugs have appeared at home; what should be done? - in detail
A confirmed presence of Cimex lectularius in a dwelling requires immediate, systematic action.
First, isolate the infestation. Remove bedding, curtains, and clothing from the affected area and place each item in sealed plastic bags. Wash fabrics in hot water (≥ 60 °C) and dry on high heat for at least 30 minutes; heat kills all life stages.
Second, eliminate hiding places. Vacuum mattresses, box springs, bed frames, furniture seams, and floor cracks thoroughly. Empty the vacuum canister into a sealed bag and discard outdoors. Use a stiff brush to dislodge insects from crevices, then wipe surfaces with a solution of 70 % isopropyl alcohol.
Third, apply targeted insecticide treatments. Select products registered for bed‑bug control, such as pyrethroid‑based sprays, silica‑based dust, or diatomaceous earth. Follow label instructions precisely: treat seams, headboards, baseboards, and any cracks. For resistant populations, consider a combination of chemical and non‑chemical methods.
Fourth, employ heat or cold remediation. Professional equipment can raise room temperatures to 50 °C for 30 minutes or lower them to –18 °C for several days, both of which are lethal to all stages.
Fifth, monitor progress. Install passive interceptors beneath each leg of the bed and furniture. Replace interceptors weekly and record captures to assess efficacy.
Sixth, prevent re‑infestation. Encase mattresses and box springs in certified, zippered covers that remain closed for at least one year. Reduce clutter, seal cracks in walls and flooring, and inspect second‑hand items before introduction.
Seventh, consider professional extermination. Certified pest‑management operators possess expertise, equipment, and access to advanced products unavailable to consumers. Engage them promptly if the infestation spans multiple rooms or persists after initial measures.
Finally, maintain vigilance. Conduct monthly visual inspections and continue using interceptors for at least six months. Promptly address any new signs to avoid resurgence.
