How is delcid prepared for a bedbug treatment? - briefly
Delcid is diluted with water to a concentration of 0.5 %–1 % by weight and applied with a sprayer to all infested surfaces, covering cracks and crevices thoroughly. The treatment is left to dry for 30–60 minutes before re‑entering the area.
How is delcid prepared for a bedbug treatment? - in detail
Delcid is a liquid formulation containing a synthetic pyrethroid that targets Cimex lectularius. Preparation for a residential infestation follows a defined sequence to ensure efficacy and safety.
The process begins with accurate measurement of the concentrate. A calibrated scale determines the required volume based on the surface area to be treated, typically expressed in milliliters per square meter. The calculated amount is transferred into a clean, chemically resistant container.
Next, the concentrate is diluted with a compatible solvent, most commonly de‑ionised water. The water temperature is maintained between 20 °C and 25 °C to promote uniform dissolution. The solvent is added gradually while stirring with a low‑speed mechanical agitator to avoid foam formation.
After the active ingredient is fully dissolved, a non‑ionic surfactant is introduced at 0.5 % v/v. The surfactant reduces surface tension, improving penetration into crevices and fabric fibers where bedbugs hide. The mixture is stirred for an additional two minutes to achieve a homogenous emulsion.
The solution is then passed through a 0.45 µm filter to remove particulate contaminants that could clog spray nozzles. Filtration is performed under a laminar flow hood to minimize aerosol exposure.
Prepared product is poured into a calibrated spray tank equipped with a fine‑mist nozzle. The tank is sealed, labeled with concentration, batch number, preparation date, and a hazard warning, and stored at 15 °C – 30 °C away from direct sunlight.
Personal protective equipment (gloves, goggles, respirator) is mandatory throughout the procedure. Ventilation must be ensured in the preparation area, and any spills are neutralised with an absorbent material before disposal according to local hazardous waste regulations.
