How to eradicate lice in a chicken coop? - briefly
First, empty the coop, scrub all surfaces with hot water, apply a veterinarian‑approved acaricide, and replace the bedding. Then, treat the chickens with the same product according to label directions and repeat after 7–10 days to break the lice life cycle.
How to eradicate lice in a chicken coop? - in detail
Lice infestations in a poultry enclosure can be eliminated through a systematic approach that combines thorough cleaning, targeted treatment, and ongoing prevention.
First, remove all birds from the coop and place them in a secure, lice‑free holding area. While the birds are out, discard any broken eggs, dead chickens, and heavily soiled bedding. Scrape the floor, perches, nesting boxes, and any wooden surfaces to eliminate crevices where lice hide. Wash all removable items—feeders, waterers, and nesting boxes—with hot, soapy water, then soak them in a diluted bleach solution (1 % sodium hypochlorite) for at least 15 minutes. Rinse thoroughly and allow everything to dry completely before returning it to the coop.
Second, apply an approved insecticidal treatment directly to the interior of the enclosure. Options include:
- Pyrethrin‑based sprays: Apply according to label directions, covering all surfaces, especially cracks and joints. Repeat after 7–10 days to catch newly hatched lice.
- Spinosad dust: Sprinkle a thin layer on the floor and perches; the dust adheres to the insects and is safe for birds when used as directed.
- Diatomaceous earth (food grade): Lightly dust the floor and nesting boxes; the abrasive particles dehydrate lice. Reapply after cleaning or heavy rain.
When using chemicals, wear protective gloves and ensure adequate ventilation. Avoid over‑application, which can stress the flock.
Third, treat the birds themselves. A brief dusting with food‑grade diatomaceous earth or a commercial poultry lice powder can be effective. Gently coat each bird, focusing on the vent area, under the wings, and around the neck. Do not use products labeled for mammals, as they may be toxic to chickens.
Finally, implement preventive measures to stop re‑infestation:
- Replace litter weekly with fresh, dry material such as pine shavings.
- Keep the coop dry; repair leaks and improve ventilation to reduce humidity, which favors lice development.
- Rotate perches and nesting boxes periodically, cleaning and disinfecting them each rotation.
- Conduct a visual inspection of the flock at least once a week, looking for tiny, moving specks on the skin or feathers.
- Limit contact with wild birds and rodents, which can serve as carriers.
By following this comprehensive protocol—removing birds, deep‑cleaning the environment, applying appropriate treatments, treating the flock, and maintaining strict hygiene—the lice population can be eradicated and the risk of recurrence minimized.
