How to eliminate lice with dichlorvos? - in detail
Dichlorvos, an organophosphate insecticide, acts on the nervous system of head‑lice, causing rapid paralysis and death. Effective eradication requires precise preparation, controlled exposure, and strict safety measures.
The standard protocol begins with selecting a formulation approved for lice treatment, typically a 0.5 % aqueous solution. Measure the product according to the manufacturer’s label, usually 10 ml per liter of water for a full‑body wash. Apply the solution to clean, damp hair, ensuring thorough saturation of the scalp and all hair shafts. Maintain contact for the duration specified—commonly 10–15 minutes—then rinse with ample water.
Key safety considerations include:
- Wearing disposable gloves and protective eyewear during mixing and application.
- Keeping the treated individual away from food, drink, and open wounds for at least one hour.
- Ventilating the treatment area to prevent inhalation of vapors.
- Storing unused solution in a locked container out of reach of children and pets.
After treatment, repeat the procedure after seven days to eliminate any newly hatched nymphs that survived the initial exposure. Inspect hair with a fine‑tooth comb before each repeat, removing dead insects and debris.
Potential adverse effects are limited to mild scalp irritation, transient itching, or temporary discoloration of hair. Severe reactions—such as excessive salivation, muscle weakness, or respiratory distress—require immediate medical attention.
Disposal guidelines mandate diluting residual solution with at least ten times the volume of water, then discarding it in a sealed container placed in a hazardous‑waste bin. Do not pour undiluted chemicals down household drains.
Because dichlorvos is a regulated pesticide, many jurisdictions restrict its over‑the‑counter availability. Verify local regulations and consult a licensed pharmacist or healthcare professional before purchase.
In summary, successful lice eradication with dichlorvos hinges on accurate dosing, thorough application, repeat treatment after a week, and rigorous adherence to safety and disposal protocols.
