How to remove lice with dichlorvos? - in detail

Dichlorvos, an organophosphate insecticide, is effective against head‑lice infestations when applied correctly. The compound acts by inhibiting acetylcholinesterase, causing paralysis and death of the parasite within minutes of contact.

Preparation

  • Verify product concentration; commercial formulations typically contain 0.5–2 % dichlorvos.
  • Wear nitrile gloves and protective eyewear to prevent dermal and ocular exposure.
  • Ensure the treatment area is well‑ventilated; open windows or use a fan.

Application Procedure

  1. Dampen a clean comb or spray bottle with the solution, avoiding excess liquid that could soak the scalp.
  2. Apply a thin, even coating to the hair and scalp, focusing on the nape and behind the ears where lice congregate.
  3. Allow the residue to remain for 5–10 minutes; this duration is sufficient for the insecticide to act without causing unnecessary skin irritation.
  4. Rinse hair thoroughly with lukewarm water and a mild shampoo to remove residual chemical.
  5. Use a fine‑toothed lice comb to remove dead insects and nits; repeat combing at 24‑hour intervals for three days to catch any newly hatched lice.

Safety Measures

  • Do not treat children under two years or pregnant individuals; organophosphates pose systemic toxicity risks.
  • Store the product in a locked container away from food, pets, and children.
  • In case of accidental ingestion or prolonged skin contact, seek medical attention immediately; provide the product label for accurate treatment.

Disposal

  • Dilute any leftover solution with water and pour it down a drain while flushing with ample water.
  • Dispose of empty containers according to local hazardous waste guidelines.

Monitoring

  • Examine the scalp daily for live lice; absence of movement after the third combing session indicates successful eradication.
  • If infestation persists, consider a second treatment cycle after a 7‑day interval or consult a healthcare professional for alternative options.
