Chicken lice may not be the most glamorous topic, but they’re a critical concern for chicken owners everywhere. These pesky pests are becoming more prevalent, especially among free-range flocks and backyard flocks.

Let’s take a closer look at chicken lice, understand why they’re becoming more problematic and uncover effective treatment and prevention strategies, including the role of diatomaceous earth.

Why Are Chicken Lice Becoming a Bigger Problem?

Lice aren’t exactly new to the poultry scene, but recent research has highlighted their increasing significance. Historically, lice were not considered major pests for chickens. However, a groundbreaking study by UC Riverside, published in Parasites & Vectors, has changed that perspective.

The study revealed that lice are feeding on the skin and blood of free-range chickens, infecting them at much higher rates than caged flocks. This is particularly relevant in states like California where cage-free egg production is the norm.

The research uncovered unexpected findings, including skin lesions associated with chicken body lice, which had not been documented before.

Signs and Symptoms of Chicken Lice

Recognizing chicken lice early can save you a lot of trouble. Here’s what to watch for:

• Bald Spots and Feather Loss: One of the most noticeable signs of lice infestation is bald patches or a significant loss of feathers. Lice feed on the skin, which can lead to irritation and feather loss.

• Excessive Pecking and Itching: Chickens with lice often peck at themselves more than usual and preen excessively as well as exhibit signs of itching or discomfort. This behavior can lead to more feather loss and skin damage.

• Reduced Egg Production: Lice infestations can stress your chickens, leading to decreased egg production. If you notice a drop in eggs, it might be worth checking for lice.

• Visible Lice: Sometimes, you may see the lice themselves. They’re small, wingless insects that can be hard to spot without close inspection. They typically live close to the skin and feathers and look similar to sesame seeds.

Preventing Lice on Chickens

Prevention is always better than a cure, and with chicken lice, there are several proactive steps you can take:

1. Maintain Clean Housing: Regularly clean and disinfect your chickens’ coop and nesting areas. Lice thrive in dirty environments, so keeping things clean can help deter them.

2. Monitor and Isolate New Birds: If you’re introducing new chickens to your flock, keep them isolated until you’re sure they’re lice-free. This will prevent any potential spread of pests to your existing flock.

3. Regular Inspections: Frequently check your chickens for signs of lice. Early detection can prevent a small problem from becoming a big issue. Make sure to quarantine birds with lice until they’re gone.

4. Proper Nutrition: Healthy chickens are better equipped to fend off pests. Ensure your flock is getting a balanced diet to maintain their overall health.

5. Pest Control: While it’s difficult to completely prevent wild birds, you can reduce rodent presence by sealing gaps, storing food off the ground or in secure containers and keeping the coop area clean. Additionally, remove eggs daily to avoid attracting rodents.

Treating Lice on Chickens

Don’t panic if you find lice on your chickens. Chicken lice are host-specific and can’t survive on humans or non-bird domestic pets. They can only feed on one or a few closely related animal species. And luckily, there are several effective treatment options available to help manage the situation and keep your flock healthy.

One of the most common treatments is using permethrin sprays. Permethrin is a widely used insecticide that effectively kills lice on contact. When using permethrin, it’s essential to carefully follow the instructions provided on the product. This ensures that the treatment is applied safely and effectively without causing harm to your chickens. It’s important to cover the entire body of the chicken, paying particular attention to areas where lice and nits (lice eggs) may hide, such as under the wings and around the vent.

For those who prefer a more natural approach, there are alternative remedies like natural dust baths. One popular choice among chicken owners is diatomaceous earth, a fine powder made from the fossilized remains of tiny aquatic organisms.

Diatomaceous earth can be sprinkled in the areas where chickens typically dust bathe like Preen Queen dust bath additive. When chickens roll in the dust, the diatomaceous earth gets into their feathers and onto their skin, helping to remove moisture and kill lice. It’s important to use food-grade diatomaceous earth and to apply it in well-ventilated areas to avoid respiratory issues for both you and your chickens.

Myths About Diatomaceous Earth for Chickens

Diatomaceous earth (DE) is a popular natural remedy among poultry keepers, but there are a few myths surrounding its use:

• It’s Not a Pesticide: DE works by physically damaging the exoskeletons of insects, not through chemical action. It’s not a traditional pesticide, but it can still be effective in controlling lice and mites.

• It’s Safe in Moderation: When used correctly, DE is safe for chickens. However, excessive use or inhalation of dust can be harmful. Always use it in well-ventilated areas and in moderation. Read the directions carefully on the packaging before using.

• It’s Not a Cure-All: DE can help control lice, but it’s not a guaranteed solution for severe infestations. It’s best used as part of an integrated pest management strategy. Always consult your veterinarian for serious infestations.

Diatomaceous Earth for Chicken Lice and Mites

As stated above, diatomaceous earth can be a valuable tool in managing chicken lice and mites. Here’s how to use it effectively:

Application Methods

1. Dust Bath Additive:

• Usage: Mix food-grade diatomaceous earth, such as Preen Queen, into your chickens’ dust bath areas. This allows chickens to coat themselves with the powder, helping eliminate lice and mites on their bodies.

• Application: Sprinkle a generous amount of Preen Queen containing DE into the dust bath and mix it thoroughly with the soil or sand. This helps the DE reach the chickens’ skin as they bathe, providing a natural way to control parasites.

2. Litter Treatment:

• Usage: Apply DE directly to the bedding and the coop floor to target lice and mites in the chickens’ environment. We recommend using Coop Recuperate. This method helps reduce the risk of re-infestation by addressing the habitat where parasites may live and breed.

• Application: After cleaning the coop, sprinkle a thin layer of food-grade DE, like Coop Recuperate, across the entire floor and mix it into the bedding material. This will help keep the environment inhospitable for parasites.

Frequency of DE

• Regular Reapplication: Consistently apply DE, especially after cleaning the coop or refreshing the bedding. We recommend applying Coop Recuperate at least two times per week for prevention. Regular use helps maintain control over lice and mite populations, ensuring a healthier environment for your chickens.

Bottom line, while chicken lice might seem like a small issue, they can have a significant impact on your flock’s health and productivity! Remember, a clean environment, using DE and regular checks are your best defense against these unwelcome pests!
