How to prepare an apartment for disinfection from bed bugs using cold fog? - briefly
Clear clutter, wash all bedding at high temperature, vacuum carpets and upholstery thoroughly, and seal cracks or gaps where insects may hide. Cover furniture with plastic sheeting, disable ventilation, and apply the cold‑fog treatment following the manufacturer’s guidelines to ensure complete coverage before re‑entering the premises.
How to prepare an apartment for disinfection from bed bugs using cold fog? - in detail
Before applying a cold‑fog treatment, eliminate any factors that could hinder the insecticide’s reach. Begin by clearing the living space of items that block airflow or conceal insects. Remove clothing, bedding, curtains, and fabric décor; wash all washable textiles in hot water (minimum 60 °C) and dry on high heat. Place non‑washable fabrics in sealed plastic bags for later treatment.
Vacuum every floor surface, mattress seams, upholstered furniture, and crevices. Use a vacuum equipped with a HEPA filter; discard the bag or clean the canister in an outdoor trash container to prevent re‑infestation. After vacuuming, seal cracks, gaps around baseboards, window frames, and pipe penetrations with silicone caulk or expanding foam. This prevents fog from escaping and forces it deeper into hiding places.
Relocate furniture to create open pathways for the fog generator. Position large items against walls, leaving at least a 30‑cm gap on all sides. For built‑in wardrobes and cabinets, leave doors ajar. Cover food, dishes, and kitchen utensils with airtight containers or plastic wrap. Store pet supplies, toys, and personal items in sealed bins; evacuate pets and plants from the premises for the duration of the procedure.
Inspect the electrical system. Turn off all appliances, unplug devices, and switch off circuit breakers where possible. Close windows, doors, and ventilation ducts; install temporary plastic sheeting over vents if they cannot be sealed. Ensure the generator’s nozzle is calibrated for the room volume according to the manufacturer’s instructions.
Activate the cold‑fog unit, following the recommended dosage per cubic meter. Allow the fog to circulate for the prescribed exposure time, typically 30–45 minutes, without disturbance. After the exposure period, ventilate the apartment by opening windows and using fans to exhaust residual aerosol. Maintain airflow for at least one hour before re‑entering.
Conduct a post‑treatment inspection. Check seams, cracks, and furniture for any remaining activity. Repeat the fog application if necessary, adhering to the interval specified by the product label. Finally, replace all sealed items, re‑install furniture, and resume normal occupancy only after confirming that the environment is clear of active infestations.
