How to remove lice from pigs? - briefly

Apply a veterinary‑approved topical insecticide to the infested regions and comb the skin with a fine‑toothed lice comb to eliminate live lice and eggs; repeat the treatment after 7–10 days to interrupt the life cycle.

How to remove lice from pigs? - in detail

Eliminating lice infestations in swine requires a systematic approach that combines environmental management, chemical treatment, and ongoing monitoring.

First, isolate affected animals to prevent spread. Move them to a clean pen with fresh bedding, removing all organic debris that can harbor parasites. Clean and disinfect the original enclosure using a high‑temperature steam cleaner or a solution of 1 % sodium hypochlorite, allowing surfaces to dry completely before reuse.

Second, apply an appropriate ectoparasiticide. Recommended products include organophosphate dips (e.g., diazinon) or pyrethrin‑based sprays formulated for livestock. Follow the manufacturer’s dosage guidelines precisely: typically 5 ml of concentrate per 10 kg of body weight, administered by thorough soaking or thorough spraying of the animal’s coat, ensuring coverage of the neck, ears, and ventral areas. Wear protective gloves and eyewear, and observe the required withdrawal period before the animals enter the food chain.

Third, treat the environment. Distribute a residual insecticide—such as a pyrethroid dust or a pour‑on formulation—on walls, floors, and feeding equipment. Repeat application after 7–10 days to interrupt the lice life cycle, which generally spans 14–21 days from egg to adult.

Fourth, implement a regular inspection schedule. Examine each pig weekly for signs of infestation: crusty or irritated skin, visible insects, or excessive scratching. Record findings and adjust treatment frequency if recurrence is observed.

Finally, maintain preventive measures. Provide adequate nutrition to support skin health, keep housing dry and well‑ventilated, and rotate pastures when possible. Regularly clean water troughs and feed bins to reduce secondary sources of contamination.

By integrating isolation, targeted chemical control, environmental decontamination, systematic monitoring, and preventive husbandry, lice can be effectively eradicated from a swine herd.
