How can lice be treated in hens? - briefly
Effective control relies on applying approved poultry insecticides, such as pyrethrin sprays or oral ivermectin, directly to the birds and their housing. Complementary measures include thorough cleaning, litter replacement, and regular monitoring to prevent reinfestation.
How can lice be treated in hens? - in detail
Lice infestations in laying hens require a systematic approach that combines environmental hygiene, chemical control, and monitoring. Effective management begins with thorough cleaning of the coop. Remove all bedding, disinfect surfaces with a poultry‑safe sanitizer, and replace with fresh, dry material. Regular removal of manure and dust reduces the habitat where lice thrive.
Chemical options include:
- Topical insecticides: Sprays or dusts containing pyrethrins, permethrin, or carbaryl are applied directly to the birds’ feathers, focusing on the vent area, underwings, and neck. Follow label dosage and repeat after the life cycle of the parasite (typically 7–10 days).
- Systemic medications: Oral or injectable products such as ivermectin or selamectin provide internal protection and can eliminate hidden stages. Dosage must be calculated per kilogram of body weight and administered according to veterinary guidance.
- Feed additives: Incorporating diatomaceous earth or herbal extracts (e.g., neem, rosemary) into the diet can deter external parasites, though efficacy is lower than pharmaceutical treatments.
Non‑chemical measures enhance control:
- Dust bathing areas: Provide clean sand or ash to encourage natural grooming, which helps dislodge lice.
- Regular inspections: Conduct weekly visual checks, looking for small, translucent insects moving quickly through the plumage or signs of feather damage and irritation.
- Quarantine: Isolate newly acquired birds for at least two weeks and treat prophylactically before integration.
Integrated pest management (IPM) combines these strategies. Begin with a deep clean, apply a short‑acting insecticide, monitor the flock for two weeks, then repeat treatment if live lice are still observed. Record all interventions, dates, and product batch numbers to track effectiveness and adjust the protocol if resistance emerges. Veterinary consultation is recommended for severe infestations or when using prescription‑only medications.
