How to fight lice on chickens? - briefly

Apply a permethrin‑based powder or pyrethrin spray directly to the birds, then clean the coop thoroughly and provide daily dust‑bath opportunities. Rotate treatments and inspect the flock each day to stop re‑infestation.

How to fight lice on chickens? - in detail

Lice infestations in poultry cause feather damage, reduced egg production, and weight loss. Prompt detection and a systematic control program are essential for maintaining flock health.

The first step is accurate identification. Examine birds daily, focusing on the vent area, under the wings, and around the neck. Adult lice appear as small, tan or brown insects about 2–4 mm long; their nymphs are lighter and translucent. Heavy infestations produce visible debris and feather loss.

A comprehensive eradication plan combines sanitation, chemical treatment, and biological measures.

  • Environmental sanitation

    • Remove droppings, feathers, and bedding daily.
    • Replace litter with fresh material at least once a week.
    • Disinfect coops using a solution of 1 % sodium hypochlorite or a commercial poultry sanitizer; allow a 24‑hour dry period before re‑stocking.
  • Chemical control

    • Apply a licensed poultry insecticide (e.g., pyrethrin‑based spray) directly to the vent, underwing, and neck regions. Follow label dosage and withdrawal times precisely.
    • For resistant populations, rotate to a different class such as carbaryl or organophosphate, adhering to veterinary guidance.
  • Natural alternatives

    • Dust birds with diatomaceous earth (food‑grade) at a rate of 1 g per bird, ensuring thorough coverage of the vent and feather bases.
    • Use a 5 % aqueous solution of neem oil as a spray, repeating every 7 days for three applications.
  • Biological support

    • Introduce predatory mites (e.g., Hypoaspis miles) to the coop environment; they consume lice eggs and nymphs.
    • Maintain adequate ventilation and low humidity (below 60 %) to create unfavorable conditions for lice development.
  • Monitoring and follow‑up

    • Conduct weekly inspections for at least six weeks after treatment.
    • Record infestation levels per pen; adjust treatment frequency if counts exceed 5 % of the flock.

Consistent implementation of these measures reduces lice populations, improves bird welfare, and safeguards production performance. Regular veterinary consultation ensures compliance with drug regulations and adapts the program to emerging resistance patterns.
