How to use dichlorvos against bedbugs? - briefly
Apply a diluted dichlorvos spray directly to infested areas, concentrating on cracks, seams, and mattress edges while wearing protective gloves and ensuring adequate ventilation. Repeat the treatment after 7–10 days to eliminate newly hatched insects.
How to use dichlorvos against bedbugs? - in detail
Dichlorvos, an organophosphate insecticide, disrupts the nervous system of bed‑bugs by inhibiting acetylcholinesterase, leading to rapid paralysis and death. Its high volatility enables quick penetration of cracks and crevices where insects hide.
Before any treatment, the area must be cleared of food, dishes and personal items. Protective equipment—gloves, goggles, respirator—should be worn, and adequate ventilation ensured to prevent inhalation of vapors. The product’s label provides specific safety limits; adherence is mandatory.
Solution preparation follows the manufacturer’s recommended concentration, typically 0.5 % to 1 % active ingredient for indoor use. Dilution is performed with clean water, mixing thoroughly to achieve a homogeneous suspension. Excess liquid should be discarded according to local hazardous‑waste regulations.
Application methods include:
- Direct spray – Apply a fine mist onto infested zones, focusing on seams, mattress folds, baseboards, and furniture joints. Avoid oversaturation; a light coating suffices.
- Fogging – Use a thermal fogger to disperse vapor throughout the room, allowing the agent to reach hidden spaces. Operate the fogger for the time specified on the product label, then seal the room for the recommended exposure period.
- Residual treatment – Impregnate porous surfaces (e.g., fabric, wood) with the prepared solution, permitting the insecticide to remain active for several weeks. Re‑application may be necessary after heavy cleaning.
After treatment, maintain the environment at the specified temperature and humidity to maximize efficacy. Conduct a thorough inspection after 48 hours; repeat application if live specimens are detected. Dispose of used applicators and containers in compliance with hazardous‑waste guidelines. Continuous monitoring and periodic retreatment form the core of an effective eradication program.
