How to Treat Lice Effectively: Key Points on Medication and Prevention for Livestock and Poultry Lice Control

Lice are a type of small parasite that lives on the body surface of poultry and livestock, surviving by sucking blood or pecking at feathers and skin flakes, with chicken lice and mites being the most common on farms. After poultry and livestock become infested with lice, they often show restlessness, feather pecking and hair loss, and reddened skin; over time they become emaciated and anemic, and the egg production of laying hens also drops noticeably, so prompt treatment is necessary once lice are found.

Treating lice should follow the principle of killing both the parasites and those in the environment at the same time. For chicken flocks, spraying or dipping with medication can be used; choose low-toxicity, highly effective insecticides, dilute them according to the instructions, and spray the feathers and skin, taking special care to cover areas where lice tend to gather, such as under the wings and around the vent. For livestock such as pigs, cattle and sheep, the medication can be given by dipping or by pouring it over the body surface; the specific drugs and methods should be used only after consulting a local veterinarian.

Because ordinary drugs find it difficult to kill lice eggs, a second treatment should be repeated after an interval following the first application to kill the newly hatched larvae, and only then can the infestation be eliminated at the root. At the same time, the housing environment must be treated as well: clean up and replace bedding, and carefully spray wall cracks, perches, cages and other such places, otherwise the eggs hidden in the environment will repeatedly reinfect the poultry and livestock.

Daily prevention is more important than treatment. Keeping the housing clean, dry and well ventilated, disinfecting regularly and replacing bedding, and isolating newly introduced poultry and livestock for observation first and only mixing them into the flock after confirming they are lice-free can all effectively reduce lice problems. During medication, pay attention to safety as well: avoid contaminating feed and drinking water with the liquid, and observe withdrawal period requirements to ensure the food safety of eggs and livestock products.
