How should I use bedbug dust in an apartment? - in detail
Applying insecticidal powder for bedbugs in a residential unit requires careful preparation, precise placement, and thorough safety measures.
Begin by removing all bedding, curtains, and fabrics that can be laundered. Wash items in hot water (≥ 60 °C) and dry on high heat for at least 30 minutes. Store items that cannot be washed in sealed plastic bags to prevent re‑infestation.
Next, clear the area where the dust will be used. Vacuum carpets, floor seams, baseboards, and upholstered furniture to eliminate debris that could block the powder. Dispose of vacuum contents in a sealed bag outside the building.
Measure the recommended amount of dust according to the product label—typically a fine, even layer covering all cracks, crevices, and voids where insects hide. Use a hand‑held duster or a small brush to distribute the powder into:
- Mattress seams, box‑spring edges, and headboard joints
- Bed frame joints and slats
- Sofa cushions, under the upholstery, and inside frame cracks
- Behind picture frames, mirrors, and wall hangings
- Floor‑board gaps, baseboard edges, and door thresholds
- Electrical outlet covers, switch plates, and appliance crevices (avoid direct contact with wiring)
Do not apply dust on surfaces that will be directly contacted by skin or pets. After placement, leave the powder undisturbed for at least 72 hours. During this period, restrict entry to the treated rooms, and keep children and pets out.
After the exposure time, re‑vacuum the treated spaces using a HEPA‑filter vacuum to remove residual particles. Clean all surfaces with a damp cloth to reduce inhalation risk.
Finally, monitor for signs of activity for several weeks. Repeat the application if live insects are still observed, following the same safety protocol. Maintain regular housekeeping, seal new cracks, and consider integrating additional control methods such as heat treatment or professional inspection for long‑term eradication.
