How to use dichlorvos against fleas? - in detail
Dichlorvos, an organophosphate insecticide, provides rapid flea knock‑down when applied correctly. The product must be diluted according to the manufacturer’s label, typically 1 ml of concentrate per 1 liter of water for indoor use. Mixing should occur in a well‑ventilated area; stir until the solution becomes homogeneous.
Application procedures include:
- Surface spray – apply the diluted solution to carpets, pet bedding, and cracks where fleas hide. Ensure thorough coverage without oversaturation.
- Fogging – use a certified fogger to disperse the aerosol throughout rooms, focusing on dark, undisturbed zones.
- Direct spot treatment – target known flea infestations on furniture legs, baseboards, and under appliances with a handheld sprayer.
Safety measures are mandatory:
- Wear chemical‑resistant gloves, goggles, and a particulate mask.
- Remove pets and humans from treated spaces for at least 2 hours, then ventilate by opening windows and using fans.
- Store unused concentrate in a locked container away from food and children.
Reapplication timing depends on infestation severity. For moderate infestations, repeat treatment after 7 days; for heavy infestations, a second application after 3 days followed by a third at day 10 improves control. Do not exceed the maximum number of applications listed on the label.
Disposal guidelines require empty containers to be rinsed, then placed in a sealed bag for hazardous‑waste collection. Do not pour residual solution down drains, as it can contaminate water sources.
Effectiveness monitoring involves weekly visual inspection of pet fur and bedding, and the use of sticky traps placed near suspected flea habitats. A decline in trapped fleas confirms adequate coverage; persistent counts indicate the need for additional treatment or alternative control strategies.
