Detailed Explanation of Chicken Lice Control Techniques and Methods
Chicken lice are a common type of external parasite of poultry, mainly living on the feathers and skin of chickens. Chicken lice are permanent parasites, and their entire life cycle takes place on the chicken's body... Feather lice can live on a chicken's body for several months, but once they leave, they can only survive 5-7 days, so the development cycle of chicken lice is 3-4 weeks. They are also one of the most common external parasites of poultry; about the size of a sesame seed, they have 6 legs like other insects, and there are many species, about 20 or more; they can occur in all four seasons, and autumn in particular is a period of high incidence for chicken lice, with reproduction occurring once every 6 days when the temperature reaches 25°C; humans, livestock, and poultry (especially laying hens and breeding hens on chicken farms that have raised chickens for many years) are all susceptible to lice infestation. Those parasitic on chickens mainly include the chicken body louse, head louse, and feather louse. Some feed on feathers and skin flakes, while others pierce and bite the skin and suck blood, affecting the growth, development, and production performance of chickens. In mild cases, chicken growth is stunted, and laying hens reduce egg production or stop laying entirely; in severe cases, the comb becomes pale, and the chicken dies from anemia caused by excessive blood loss.
Symptoms of Chicken Lice Infestation
Affected chickens are extremely itchy and restless, jumping and flying about, often pecking at their own feathers and skin, resulting in feather loss, skin damage, decreased appetite, progressive weight loss and anemia, listlessness, nutritional deficiency, and then anemia symptoms and even death. Lice on chicks affect growth and development; lice on laying hens cause a drop in egg production.
Pathogenic Characteristics of Chicken Lice
Chicken lice are permanent parasites that live and reproduce among the feathers of chickens and do not actively leave the chicken's body. When a female louse lays eggs, it secretes a sticky substance that glues clusters of eggs to the base of the feathers, and after 5-10 days the larvae hatch. The larvae resemble the adults in appearance, and after 2-3 weeks and 3-5 molts they develop into adults, which can then lay eggs, with a lifespan of several months. Chicken lice can lay eggs and reproduce in all four seasons, with the greatest reproduction in winter. Under suitable conditions, a single pair of chicken lice can produce more than 100,000 descendants from before winter to the beginning of spring. When chickens have lice, the itching and irritation cause them to frequently shake their feathers, which scatters some chicken lice off the body; the scattered lice can burrow into the feathers of other chickens and settle there again, or they may be carried by certain vectors (the soles of people's shoes, small animals, etc.) to other flocks and cause those flocks to become infested with chicken lice. If these opportunities do not arise, chicken lice on the ground, in bedding, chicken manure, and other environments will die after a few days because they cannot obtain food.
Control Methods for Chicken Lice
The most common method for killing lice on chickens is spraying, followed by medicated bathing. Since the entire chicken must be sprayed or soaked with the solution, low-toxicity and safe drugs should be selected. Natural pyrethrins are very safe, but relatively expensive, so currently synthetic "pyrethroids" are mainly used, such as beta-cypermethrin, whose efficacy is superior to natural pyrethrins and which is also relatively safe when used correctly; because of its high efficacy, basically one treatment can completely eliminate chicken lice; if the situation is severe, the drug can be applied again after 10 days. Deltamethrin, fenvalerate, and others also have a certain effect on killing chicken lice, but because they have been used for many years, resistance has become widespread nationwide, and the results are not ideal; organophosphorus insecticides such as trichlorfon and dichlorvos are highly sensitive to chickens and prone to causing poisoning, and they do not easily kill the pests completely, requiring frequent application and easily leading to resistance, so they should not be used.
Recommended Medications for Chicken Lice
Use Baiquinkang Shimanzhibisha: Baiquinkang Shimanzhibisha is one of the very few insecticides on the market that can be directly sprayed on poultry (chickens, breeding hens) to kill pests, and it can eliminate external parasites on poultry in one treatment! It also has the effect of softening and cleaning poultry feathers!
1: Unique formula.
2: Good adhesion.
3: Broad-spectrum, highly effective, low toxicity, safe for humans and poultry.
4: Convenient to use. 5: No drug residue issues.
Dilute 200ml per bottle in 4 kg of water and add 5 g of washing powder, then spray directly onto the chickens -- use an ordinary sprayer to spray against the feathers, spraying all the feathers over the chicken's entire body until slightly damp, and also apply the pesticide comprehensively to the surrounding environment -- the ground, cages, net racks, and all other environments (dilute 200ml per bottle in 2 kg of water) to ensure complete elimination of the pest source; spray again after an interval of 10 days to kill newly hatched young lice; be careful to avoid the feed troughs and drinking fountains as much as possible when applying, and use with caution on young poultry.
Using the above method: generally, no chicken lice will reappear for a year; if there are many mosquitoes and flies in the chicken house in summer, it can also keep the chicken house free of flies for more than 20 days, and free of mosquitoes, midges, blackflies, and other external parasites for about 15 days.
