How can you poison lice on chickens? - briefly
Apply a veterinary‑approved ectoparasiticide, such as a pyrethrin‑based dust or a permethrin spray, directly to the chicken’s feathers according to label directions. Repeat the application after the lice’s life cycle to achieve complete control.
How can you poison lice on chickens? - in detail
Effective chemical control of poultry lice requires knowledge of approved insecticides, correct dosage, application technique, and safety precautions.
Select an insecticide registered for avian use. Common options include:
- Organophosphates (e.g., diazinon): applied as a spray at 0.025 % concentration, 1 ml per 5 kg of bird weight. Observe a 24‑hour withdrawal period before processing.
- Pyrethroids (e.g., permethrin, cypermethrin): administered as a dust or spray at 0.1 % concentration, 0.5 g per 10 kg of bird weight. Withdrawal time varies from 0 to 48 hours depending on the product label.
- Avermectins (e.g., ivermectin): delivered orally at 0.2 mg/kg body weight, mixed in drinking water. Observe a 7‑day withdrawal before slaughter.
Prepare the solution in clean water, ensuring uniform distribution. Apply the mixture using a low‑pressure sprayer to coat the entire plumage, paying special attention to the vent area and underwings where lice congregate. For dust formulations, dust the birds lightly with a hand‑held applicator, avoiding excess that may cause respiratory irritation.
After treatment, isolate the flock for at least 48 hours to prevent reinfestation. Clean and disinfect housing, equipment, and perches with a 1 % sodium hypochlorite solution. Replace bedding material to eliminate residual eggs.
Monitor efficacy by inspecting a sample of birds 24 hours post‑application. If live lice persist, repeat the treatment after a 7‑day interval, respecting the maximum number of applications indicated on the product label.
Record all treatments, including product name, concentration, dosage, date, and withdrawal period, to maintain compliance with veterinary regulations and ensure food‑safety standards.
