What should be done if bedbugs have bitten in the house? - briefly
Clean the affected area with mild soap and apply an antihistamine or topical corticosteroid to alleviate itching and inflammation. Then launder all bedding and clothing in hot water, vacuum and seal infested spaces, and contact a professional pest‑control service for comprehensive elimination.
What should be done if bedbugs have bitten in the house? - in detail
When bedbug bites appear, act promptly to reduce discomfort and stop the infestation.
First, treat the skin. Clean each mark with mild soap and water, then apply an antiseptic. Over‑the‑counter antihistamine tablets or topical corticosteroid cream can lessen itching and swelling. If a reaction worsens—significant swelling, fever, or secondary infection—seek medical attention.
Second, confirm the presence of insects. Examine bedding, mattress seams, headboards, and furniture for live bugs, shed skins, or small dark spots (fecal stains). Use a flashlight and a thin card to probe seams; live specimens move quickly when disturbed.
Third, isolate the affected sleeping area. Strip the bed of all linens and wash them in hot water (≥ 60 °C) for at least 30 minutes, then dry on high heat. Place pillows, blankets, and mattress protectors in sealed plastic bags for a minimum of two weeks to starve any hidden insects.
Fourth, reduce hiding places. Vacuum carpets, floor cracks, and upholstered furniture thoroughly; discard the vacuum bag or clean the canister immediately. Seal cracks in walls, baseboards, and around pipes with caulk. Reduce clutter that could serve as shelter.
Fifth, apply a targeted control method. Options include:
- Heat treatment: Raise room temperature to 50 °C for several hours; heat penetrates cracks and kills all life stages.
- Cold treatment: Expose infested items to ≤ −18 °C for at least 48 hours.
- Insecticide sprays: Use products labeled for bedbugs, applying according to manufacturer instructions on cracks, crevices, and furniture frames.
- Professional extermination: Engage a licensed pest‑control service for integrated management, which often combines heat, chemicals, and monitoring devices.
Sixth, monitor progress. Install passive traps (e.g., interceptors under bed legs) and conduct weekly inspections for at least three months. Continue laundering all bedding weekly during this period.
Finally, adopt preventive habits. Encase mattresses and box springs in zippered, insect‑proof covers; inspect second‑hand furniture before bringing it indoors; avoid placing luggage on beds while traveling; and maintain regular cleaning routines.
Following these steps minimizes health effects, eliminates the current outbreak, and lowers the likelihood of future infestations.
