How can I eliminate lice at home using dichlorvos? - in detail
Dichlorvos, an organophosphate insecticide, can be employed to eradicate head‑lice infestations when applied correctly. The following protocol outlines the preparation, application, and post‑treatment procedures required for safe and effective use in a residential setting.
Prepare a solution of 0.1 % dichlorvos (1 mL of 100 % concentrate diluted in 1 L of water). Use a calibrated measuring device to ensure accurate concentration. Wear disposable gloves, a face mask, and eye protection throughout the process. Avoid inhalation and skin contact.
Apply the solution directly to the hair and scalp, saturating all strands from root to tip. Use a fine‑tooth comb to distribute the liquid evenly, ensuring coverage of hair follicles where lice and nits reside. Maintain the treatment for 10 minutes, the minimum contact time specified on most product labels.
After the exposure period, rinse the hair thoroughly with lukewarm water. Follow with a regular shampoo to remove residual chemical. Repeat the combing process with a clean nit‑comb to dislodge any remaining eggs. A second treatment 7–10 days later targets hatchlings that survived the initial application.
Clean the environment to prevent re‑infestation. Wash all bedding, clothing, and personal items in hot water (≥ 60 °C) or place them in a sealed plastic bag for 72 hours. Vacuum carpets, upholstered furniture, and car seats; discard vacuum bags immediately. Store any unused dichlorvos in its original container, locked away from children and pets.
Legal and health considerations: many jurisdictions restrict or prohibit residential use of dichlorvos due to its toxicity. Verify local regulations before purchase. If a label indicates a lower permissible concentration, adjust the mixture accordingly. In case of accidental ingestion, skin absorption, or inhalation, seek medical attention promptly and provide the product information to healthcare professionals.
For individuals unable or unwilling to use organophosphate chemicals, alternative options include permethrin‑based shampoos, ivermectin oral medication, or mechanical removal with fine‑tooth combs. These methods present lower systemic risk and are often recommended as first‑line treatments.
