How to properly conduct bedbug disinfection in a house? - briefly
Locate every infestation site, then treat with a registered insecticide, heat‑expose removable items, launder fabrics at ≥ 60 °C, and vacuum all cracks and crevices. Seal entry points, repeat inspections weekly for four weeks, and re‑apply treatment if live bugs are found.
How to properly conduct bedbug disinfection in a house? - in detail
Bedbug eradication in a residence begins with thorough inspection. Identify active infestations by locating live insects, shed skins, and dark spotting on mattresses, furniture seams, baseboards, and wall cracks. Use a bright flashlight and a magnifying lens to confirm presence.
Preparation includes isolating infested zones, removing clutter, and laundering all removable textiles. Wash bedding, curtains, and clothing at ≥ 60 °C for at least 30 minutes; dry on high heat. Vacuum carpets, upholstery, and cracks, then seal the vacuum bag in a plastic container before disposal. Seal non‑washable items in airtight bags to prevent spread.
Treatment options:
- Chemical sprays: Apply EPA‑registered pyrethroid or neonicotinoid formulations directly to hiding places, following label dosage and safety instructions. Repeat applications after 7–10 days to target newly hatched nymphs.
- Heat treatment: Raise ambient temperature of affected rooms to 50–55 °C for a minimum of 90 minutes; use calibrated heat equipment to ensure uniform penetration into furniture and wall voids.
- Steam: Direct steam at ≥ 100 °C onto seams, folds, and crevices; maintain steam contact for at least 30 seconds per spot to achieve lethal exposure.
- Desiccants: Distribute food‑grade diatomaceous earth or silica‑based powders along baseboards, under furniture, and in wall gaps; reapply after cleaning or moisture exposure.
After treatment, implement monitoring. Place sticky interceptors beneath legs of beds and sofas to capture wandering insects. Conduct weekly visual checks for at least 30 days; repeat a secondary treatment cycle if any activity persists. Maintain a regular cleaning schedule and avoid reintroducing second‑hand furniture without thorough inspection.
