How is an apartment treated for bedbugs with hot fog? - briefly
A specialist disperses a heated insecticidal fog that reaches 120‑140 °F, allowing the vapor to infiltrate upholstery, carpet fibers, and wall voids and eliminate all bed‑bug life stages. After the fog dissipates, the premises are ventilated and a final inspection verifies complete eradication.
How is an apartment treated for bedbugs with hot fog? - in detail
The treatment of a residential unit for a Cimex infestations using heated vapor follows a precise sequence designed to eradicate all life stages of the pest. Preparation, application, and post‑treatment actions are essential components of the protocol.
Initial preparation begins with the removal of clutter that could shelter insects, such as piles of clothing, bedding, and personal items. All fabrics are either laundered at temperatures above 60 °C or sealed in airtight bags. Furniture is inspected; drawers and cabinets are emptied, and any removable cushions are taken off. Electrical outlets and appliances are covered with heat‑resistant tape to protect circuitry from moisture. Ventilation is limited by sealing windows, doors, and HVAC vents with polyethylene sheeting, preventing the escape of vapor and ensuring uniform distribution.
The application phase employs a portable thermal fogger calibrated to produce a fog with a temperature range of 45–55 °C and a particle size of 10–30 µm. The device is positioned centrally, and the operator activates the unit, allowing the fog to fill the entire space for a period of 30–45 minutes. Continuous monitoring of temperature and humidity is performed with calibrated thermometers and hygrometers placed at various locations to verify that target conditions (minimum 45 °C for at least 30 minutes) are achieved throughout the environment. The fog penetrates cracks, seams, and voids, reaching concealed areas where bedbugs reside.
After the exposure period, the fog is exhausted using high‑capacity extractors equipped with HEPA filters. The extraction process continues until ambient temperature returns to normal levels and residual moisture is removed. All sealed items are unwrapped, and the unit is ventilated for several hours before re‑occupation. A final inspection confirms the absence of live insects, eggs, or exuviae. Documentation of temperature logs, exposure duration, and equipment settings is retained for compliance and future reference.
