How to kill lice on chickens? - briefly

Apply a poultry‑approved insecticide, such as pyrethrin spray or dust, to the birds and their environment according to label instructions, ensuring complete coverage of the flock and coop. Repeat the application after 7–10 days and replace bedding to interrupt the lice life cycle.

How to kill lice on chickens? - in detail

Lice infestations on poultry cause irritation, feather loss, and reduced egg production. Effective eradication requires a systematic approach: diagnosis, immediate treatment, and long‑term prevention.

First, confirm the presence of lice by inspecting the bird’s vent area, under the wings, and along the neck. Adult lice are tan to brown, about 2 mm long, and move quickly across the skin. Nymphs appear smaller and lighter in color. Collect a few specimens for identification if necessary.

Immediate control options fall into three categories: chemical, organic, and environmental.

• Chemical acaricides

  1. Apply a permethrin‑based spray or dust according to the label, covering the entire bird, including under the wings and vent.
  2. Repeat the application after 7–10 days to target newly hatched lice.
  3. Observe withdrawal periods for eggs and meat; follow regulatory guidelines.

• Organic treatments

  1. Dust birds with diatomaceous earth (food‑grade) at a rate of 1 g per bird, ensuring thorough coverage.
  2. Use a 10 % neem oil solution for a spray, applied twice weekly for three weeks.
  3. Combine both methods for synergistic effect, monitoring for skin irritation.

• Environmental sanitation

  1. Remove all bedding, litter, and perches; clean the coop with hot water (≥ 60 °C) and a mild disinfectant.
  2. Replace bedding with fresh material; consider using pine shavings, which deter lice.
  3. Seal cracks and crevices where lice hide; apply a residual insecticide to the coop structure if permitted.

After treatment, re‑inspect birds weekly for at least six weeks. Persistent lice indicate resistance or incomplete environmental control, requiring a switch to an alternative acaricide or a longer treatment schedule.

Preventive measures reduce reinfestation risk:

• Rotate bedding every 2–3 days and maintain dry conditions.
• Provide dust‑bathing areas with fine sand or ash; birds naturally groom in these substrates, removing ectoparasites.
• Limit contact with wild birds and rodents that can carry lice.
• Implement a regular health‑check program, integrating lice inspection into routine examinations.

By combining accurate diagnosis, targeted treatment, thorough coop cleaning, and consistent prevention, lice populations can be eliminated, restoring bird comfort and productivity.
