Nothing works against bedbugs, what should I do? - briefly
If standard measures are ineffective, enlist a licensed exterminator who can apply heat treatment or approved insecticides. Isolate and launder infested fabrics at ≥60 °C, then encase them in sealed plastic to stop further infestation.
Nothing works against bedbugs, what should I do? - in detail
If standard insecticides, sprays, or over‑the‑counter products have not eliminated the infestation, a systematic approach is required.
First, isolate the problem area. Strip the bed of all linens, pillowcases, and mattress protectors. Place each item in a sealed plastic bag and launder on the hottest cycle the fabric can tolerate, then dry on high heat for at least 30 minutes. Heat kills all life stages of the pest.
Second, treat the mattress and box spring. Vacuum the entire surface, including seams and crevices, using a hose attachment. Immediately empty the vacuum canister into a sealed bag and discard it outdoors. Apply a professional‑grade, EPA‑registered aerosol or dust formulation specifically labeled for bedbugs, following the product’s safety instructions. Target hidden zones such as headboard joints, bed frame bolts, and nearby baseboard cracks.
Third, address surrounding furniture and flooring. Remove clutter that offers hiding places. For upholstered pieces, steam‑clean at a temperature of 130 °C (266 °F) for a minimum of 10 seconds per spot. For hard floors, mop with hot water and a detergent, then apply a residual insecticide to baseboard edges.
Fourth, consider structural interventions. Seal all cracks, gaps, and penetrations in walls, floors, and ceilings with caulk or expanding foam. Install interceptors under each leg of the bed and furniture to monitor and capture wandering insects.
Fifth, enlist professional assistance. Certified pest‑management operators can perform:
- Whole‑room heat treatment, raising ambient temperature to 55 °C (131 °F) for 4–6 hours, ensuring penetration into voids.
- Fumigation with a registered gas, requiring temporary evacuation.
- Integrated pest‑management plans combining chemical, physical, and monitoring tactics.
Finally, implement a rigorous follow‑up schedule. Inspect the sleeping area weekly for several months, using a flashlight to examine seams, folds, and cracks. Replace intercepted insects with a fresh count to gauge progress. Maintain the high‑heat laundering routine for any new bedding or clothing that enters the environment.
By combining thorough sanitation, targeted chemical application, physical barriers, and professional heat or fumigation treatments, the infestation can be eradicated even when earlier attempts have failed. Continuous monitoring prevents re‑establishment.
