How to get rid of lice in calves? - briefly
Apply a topical insecticide approved for bovine use, following label directions, and repeat the application after the lice life cycle completes. Combine treatment with regular grooming, thorough cleaning of the environment, and isolation of affected calves to prevent reinfestation.
How to get rid of lice in calves? - in detail
Effective control of lice infestations in young cattle requires a systematic approach that combines sanitation, chemical treatment, and ongoing monitoring.
Initial inspection should identify the severity of the infestation. Look for excessive scratching, visible insects on the skin, and crusted lesions, especially around the neck, udder, and hindquarters.
Sanitation measures include removing manure, bedding, and any organic debris where lice can develop. Pastures should be rotated regularly, and grazing areas should be kept dry to reduce humidity that favors lice survival.
Chemical control is the cornerstone of treatment. Recommended products are topical insecticides approved for bovine use, such as pyrethroids (e.g., permethrin) or organophosphates (e.g., diazinon). Application steps are:
- Clean the animal’s coat with warm water and a mild detergent to remove dirt and oils.
- Dry the coat thoroughly; moisture interferes with insecticide absorption.
- Apply the insecticide evenly, following the label dosage per kilogram of body weight.
- Ensure thorough coverage of the entire body, paying special attention to folds and under the udder.
- Repeat the treatment after 7–10 days to target newly hatched lice that survived the initial dose.
Alternative options include systemic treatments such as injectable ivermectin, which provides internal protection against a broad range of parasites, including lice. Dosage must be calculated precisely according to the animal’s weight, and withdrawal periods observed before milk or meat consumption.
Environmental control complements chemical measures. After treatment, wash and disinfect equipment, feeding troughs, and handling facilities with a solution containing 1 % sodium hypochlorite. Replace bedding with clean material and allow it to dry completely before reuse.
Monitoring should continue for at least four weeks post‑treatment. Conduct weekly visual inspections and record any reappearance of lice. If infestations persist, consider rotating to a different class of insecticide to avoid resistance development.
In cases of severe infestation with secondary skin infections, veterinary consultation is essential. Antibiotics may be required to treat bacterial complications, while anti‑inflammatory drugs can alleviate discomfort.
Adhering to these steps—rigorous sanitation, correct insecticide use, environmental decontamination, and vigilant follow‑up—provides a comprehensive solution for eliminating lice in calves.
