How can you eliminate bedbugs with household means? - briefly
Use high heat (wash linens at 60 °C, dry on high heat), thorough vacuuming, and a dusting of diatomaceous earth to kill bedbugs without professional chemicals. Seal infested items in plastic bags, repeat cleaning weekly, and monitor for any remaining insects.
How can you eliminate bedbugs with household means? - in detail
Bedbugs can be eradicated with items commonly found in a home when a systematic approach is applied. The process consists of detection, preparation, treatment, and verification.
-
Identify infested zones – Examine seams of mattresses, box‑spring frames, headboards, and furniture cracks. Use a flashlight and a fine‑toothed comb to collect any visible insects or shed skins. Mark contaminated areas with tape.
-
Reduce hiding places – Remove clutter that provides shelter. Wash all bedding, curtains, and removable fabrics in hot water (≥ 60 °C) and dry on the highest heat setting for at least 30 minutes. Vacuum carpets, upholstery, and floor joints thoroughly; immediately empty the vacuum canister into a sealed bag and discard it outdoors.
-
Apply heat – Portable steam cleaners equipped with a nozzle that reaches 120 °C effectively kill bedbugs on contact. Direct steam at seams, folds, and crevices for a minimum of 10 seconds per spot. For larger items, place them in a sealed container under direct sunlight for 4–6 hours, ensuring interior temperatures exceed 45 °C.
-
Use desiccant powders – Food‑grade diatomaceous earth or silica gel can be sprinkled in cracks, baseboards, and under furniture. These powders abrade the insects’ exoskeleton, causing dehydration. Apply a thin, even layer, leave it for 48 hours, then vacuum.
-
Employ natural insecticidal solutions – Mix equal parts rubbing alcohol and water in a spray bottle; saturate affected surfaces and allow to dry. Alcohol penetrates the cuticle and destroys the nervous system. For fabric items that cannot be laundered, spray the solution lightly and expose to heat afterward.
-
Seal and isolate – Encase mattresses and box springs in zippered encasements designed to trap insects. Keep encasements on for at least 12 months; any surviving bugs will die without access to a host.
-
Monitor progress – Place sticky traps near suspected hideouts for a week after treatment. Replace traps weekly and record captures. Continue inspections weekly for a month to confirm eradication.
By combining thorough cleaning, heat exposure, desiccant powders, and targeted alcohol sprays, a household can eliminate bedbug populations without professional chemicals. Persistence and repeated verification are essential to prevent re‑infestation.
