Do Your Chickens Have Lice?

Lice are a fairly common parasite that chickens can suffer from. The most common type of lice that chickens suffer from is Menopon gallinae. Lice will live on the chicken’s skin underneath the feathers. The entire life cycle happens on the chicken so it is much easier to treat lice compared to worms. In small numbers lice don’t cause much irritation to your chickens and your chickens will try to manage their lice by having dust baths which will suffocate lice. However if your chickens have large numbers of lice living on them then they will need a bit of extra help from you.

Signs And Symptoms

  • A drop in egg production
  • Broken feathers, feather loss, overpreening
  • Red or sore skin around the vent area
  • Scratching
  • Lice crawling around the shaft of the feathers.
  • Nits — Clumps of eggs stuck to the bottom of the shaft of the feather. Most commonly around the vent area. This will be a whitish grey, and are very hard and tricky to remove.

Lice are easy to treat and your chicken should be lice free in a relatively short amount of time from when you start treatment; usually roughly 3 weeks as the life cycle of the lice is 3 weeks. As a preventative method it is a good idea to sprinkle Diatom Powder in your chickens dustbaths (or over the area they usually use for dustbaths) as this will keep the lice from being able to take hold. If there are lots of lice then you can use a lice powder to powder your chickens. If you dust your chickens with a powder all over working it into their feathers and onto the skin 3-4 times a week for 3 weeks. You will need to do this for 3 weeks as any eggs left will hatch and you will need to kill off those lice until your chicken is lice free. In the mornings you can also dust their chicken coop with the powder although be careful to not make it too dusty as dust can cause respiratory problems. Omlet stock a range of lice powders which will effectively deal with the problem.

Dealing with Lice on Goats & Sheep

Dealing with Lice on Goats (and Sheep)

Makes you itch just hearing the word, lice, doesn’t it? Imagine how your goats feel. They may be quite heavily infested by the time you notice it. Lice can often be mistaken for flecks of hay in the goat’s coat at first glance and many herd owners will at first just shrug it off as that. But look a little closer.

Goat / sheep lice are tiny bugs that are tan in color and slightly translucent. The translucency will allow you to see a black (or dark brown) center to them. That would be there internal organs (full of blood – your goat’s blood).

While the goat / sheep louse can survive off of it’s host for a matter of days (possibly up to a week) don’t worry, it won’t be making a meal out of you. Lice are specific to their host and will not cross species (they won’t infest or chickens or your horses – just other goats and sheep).

Lice are external parasites. Meaning that they attach themselves to an animal’s hair and then feed on the skin or blood.

There are two types of lice in goats: biting lice and sucking lice.

Biting lice feed on the hair and the surface of the skin. This type of lice is more of an irritant and can cause hair damage but will not harm your goats beyond that. They still need to be removed though.

Sucking lice are more of a problem than biting lice, and can cover the entire body. Sucking lice feed on the blood of the animal and in severe cases can cause anemia. These are the most commonly found sucking lice in the United States.

·Goat sucking louse (very common)

·The foot louse (prefer legs, feet, the underbelly and the scrotum)

·The African blue louse (also found in the United States)

A case of lice can occur during any season, but is most common in late fall through early spring.

Symptoms of goat lice are:

·Intense itching (though not always present)

·Open sores (from biting or rubbing the itching spots)

·Weight loss can occur

·Milk production is often decreased by up to 25%

·Anemia (in severe cases of sucking lice)

Treating a lice infestation:

Lice control is difficult because pesticides do not kill the egg of the louse.

Eggs will hatch 8 to 12 days after treatment with a pesticide, making retreatment necessary 2 weeks after the first application. We sometimes follow with a third treatment 2 weeks after the second.

·Treat the goat with either a powdered pesticide or a chemical pesticide designed to treat both types of lice.

·Treat the goat’s housing by removing (and burning) all bedding, applying a powdered pesticide and rebedding the area.

·Repeat treatment of animal in 14 days. In some cases it may be necessary to retreat at 28 days as well.

What type of pesticide to use?

There are several options for a powdered pesticide (including DE, Python Dust and Seven Dust). We like Python Dust here on Honaker Farm. If you are applying dust to the animal as treatment be sure to apply liberally and rub into the coat.

Chemical options that you can use for your animal are varied as well and range in dosing form from orally, injected to pour on. Available options are: Permethrin, Permethrin (synergized), Zeta-cypermethrin and Ivermectin (off label use – talk to your veterinarian first).

At Honaker Farm we like Python Dust and injected Ivomec 1%, we inject at the label dose for lice.

A note on DE: DE (diatomaceous earth) is not a chemical or a pesticide (per se). It is the fossilized remains of diatoms and acts more as a drying agent to the parasite by drying out the exoskeleton of the bug so that it has no protection and dies. Care should be taken that you and your animals do not breathe in the dust from DE as it has the same drying effect on the mucous membranes of your (and their) lungs.

Important Note on use of injected Ivermectin: Be aware that there is a stinging agent in Ivomec (ivermectin) that will cause the animal to have a pain reaction. This may seem that they are having a seizure or in severe pain, but it only lasts a few seconds and as long as you are prepared you’ll be fine. Using this product for goats is off label (or extra label) and should only be used with the supervision of a veterinarian.

How to Treat Lice With Diatomaceous Earth

Lice are a common household pest that can infest animals, people and homes. They feed on their hosts and spread a variety of diseases. Diatomaceous earth is a natural compound made up of microscopic fossilized creatures that have been ground up into a fine powder 12. Diatomaceous earth causes the insects to lose their outer coverings and dehydrate 12.

Wear proper attire. Diatomaceous earth can cause minor irritation of the nasal passageways and throat 12. You should wear a face mask to avoid inhaling the product. If you use it as a spray, then there is less chance of inhaling diatomaceous earth 12.

Spray or powder your animals. If you found lice on your household pet or livestock and want to get rid of them, then apply the powder generously to their coats. The diatomaceous earth can also be mixed with water and sprayed onto the animals 12. Spraying may be the best option, as the dust can irritate your pets’ noses and throats as well. The powder can also be applied to humans as well.

Check for lice. After the diatomaceous earth has been applied to your animals or people, using a lice brush to comb through and remove the dead insects 12. You should repeat this process every few days until you no longer are removing dead lice with the comb.

Spray and powder your home. You should wash and spray down your bed and other areas where the lice may be found. When you have done that, go around your home spraying the interior furniture and any cracks or crevices where they could be hiding. Spray any places where your pets or livestock frequent, such as barns, dog beds, etc.

Take care of outside. With the inside of the house taken care of, you should go outside and spray the exterior base of the home with the diatomaceous earth 12. Spread the powder throughout your grass and flower beds. It will not only kill any lice but many other insects as well.

Head Lice Information for Schools

Students diagnosed with live head lice do not need to be sent home early from school; they can go home at the end of the day, be treated, and return to class after appropriate treatment has begun. Nits may persist after treatment, but successful treatment should kill crawling lice.

Head lice can be a nuisance but they have not been shown to spread disease. Personal hygiene or cleanliness in the home or school has nothing to do with getting head lice.

Both the American Academy of Pediatrics (AAP) and the National Association of School Nurses (NASN) advocate that “no-nit” policies should be discontinued. “No-nit” policies that require a child to be free of nits before they can return to schools should be discontinued for the following reasons:

  • Many nits are more than ¼ inch from the scalp. Such nits are usually not viable and very unlikely to hatch to become crawling lice, or may in fact be empty shells, also known as ‘casings’.
  • Nits are cemented to hair shafts and are very unlikely to be transferred successfully to other people.
  • The burden of unnecessary absenteeism to the students, families and communities far outweighs the risks associated with head lice.
  • Misdiagnosis of nits is very common during nit checks conducted by nonmedical personnel.

Exactly how do you dust a chicken for lice?

My dd discovered lice on the girls. i have some lice powder—(don’t know the name of it) How do I hold the bird? How often do i do it?

Thanks in advance.



I use a mix of sevin dust. I take an old panty hose and cut off the foot. Put a good bit of the dust down in the toe and tie it off. Then I use it like a powder puff.

If you will hold them upside down and then puff it all over them you will be sure to get it down in the feathers next to the skin. They will hold out the wings or you can gently pull them out and puff the little dust ball all underneath. If you get someone to help you hold the chickens or you hold the chickens and someone else puff them you can easily do a hen from top to bottom in 30 seconds or less.

It really won’t hurt them if you are quick and gentle.

And don’t worry. Your kids can’t get chicken lice.

Love my Critters!




thanks, the panty hose trick is a great idea!

Funny, my dd comes in and wants me to check her hair b/c she’s itchy. I check her-she’s fine. then myds comes in and tells me he squashed a grey bug off his sis. So I was ready to double check, and dd chimes in saying the bugs are on the chickens. Can you say ‘wave of relief?’ I knew you can’tget chicken lice.

When do I need to repeat this? And also, what about my broody and her three (so far) new chicks?



Puff them again in about a week. Also you need to clean and dust the hen house because the lice can be in the bedding.

I would dust the broody. The chicks will get powdered by being under her wings. I think they will be fine. i have never had to dust babies before.



Thanks, MissPrissy! bunch of firsts here for me. first goats, first broody, first chicks, first bout with lice, and on Monday, first time for meat chicks.

When it rains it pours!






Showers of Blessings



I just use poultry dust (permethrin) from the co-op. This works on lice and mites. After reading the research suggesting a link between respiratory problems and turning hens upside down, I have chosen to dust them «right side up;» I wait until they perch in the evening, pull on some surgical gloves, and using a powder container I «poof» their behinds, being sure to get to the skin really well. I also gently dust under each wing, and then I put the girls to bed.

I try to do this 1x/week; I am actually going to do it right now.

I feel safe enough with this product that I do not discard eggs.

In tandem with dusting, I also use a permethrin spray (from co-op; I hand mix) for surfaces on the outside of the coop and run; I generally only do this if I notice a problem, and I wait until the girls are outside in the yard.

MissPrissy, I know you have a lot of chicken experience. I would welcome any comments you have about the research I mentioned above. Have you ever had any respiratory issues with your chix? Is this even worth worrying about?

How to Use a Lice Comb to Get Rid of Both Lice and Nits

Lice treatment is not always successful, and many parents have to deal with the fact that head lice keep coming back. Yet many people also overlook the most crucial step in their battle against these parasites: combing lice and nits.

See also:  Mosquito Repel Lore

Combing with a lice comb is actually one of the best and most reliable treatment for head lice, and here how to use a lice comb.

Indeed, if there were a contest to determine the best lice removal method, for sure the lice comb would be the winner, not the lice shampoo. According to some British Medical Journal research, lice combs are the surest way to get rid of head lice.

However, there are certain rules you should follow when using a head lice comb and here are these rules.

  • Make sure to choose a metal lice comb, not a plastic one. The best lice comb is made of steel and has very thin teeth. You can purchase these combs at CVS or Walgreens and you get to choose between several brands such as Licemeister, Liceguard or Nit Free terminator lice comb. Some people swear by the electric lice comb, which can remove adult lice very well, but they are more expensive and they do not remove nits.
  • Combing out head lice requires some preparation. Wash your hair first, to make it softer and easier to brush through. Cover your shoulder and back with a white towel. It will protect you from lice going under your clothes. You can see them easily, when they drop on a towel. And brush your hair with a regular comb to remove any knots.
  • The combing should be done from top downwards. Try to comb as close to the scalp as possible. Nits are located high up in the hair, very close to the head (usually within half an inch). Make sure to comb the hair lock by lock. This way you can remove most adult lice and lice eggs.

Do not just brush through the entire hair. Go lock by lock, selecting small portions of hair. You may braid them after you are done with combing each lock.

Or, you may move from one side of the head to another, separating the brushed hair from the un-brushed one. Clip it together with a clip.

Once you see you have combed out a lice or a nit, you should remove it from the nit comb. You may immerse it in the hot water or clean the comb, using the towel.

Comb the hair, until no nits or lice can be found on it. The combing and hair inspection should be done in clear light or sunlight. Else, you miss some of the parasites and leave them on the head.

The combing should be finished up by shampooing your hair and rinsing with warm water.

The areas of your head that lice favor the most are the back of the neck and behind the ears. So, these should be given a special attention. Lice feed on your blood and in those areas it is easier for them to get to it. Those areas of the head are the warmest, so most nits are laid there.

Some precautions have to be taken after the combing is over. Wash your clothes and clean the comb in hot or boiling water, if it is made of steel.

The combing out of head lice is not a one time treatment. It has to be done over and over again for several days in a row. Some live lice may lay more nits and you should not allow for those nits to hatch.

Lice combing is a time consuming task. It should be done thoroughly and may take a couple of hours every time you do it. It can be tiresome for kids, so make sure to provide them with some kind of entertainment during this process.

When you get re-infested with head lice, there is no need to purchase a new lice comb. Use the old one, and only make sure to clean it well every time you use it.


That seems to be working very well. I am a licensed cosmetologist and I used a nit comb and a Jeweler’s loupe so that I can see the actual lice on the nit comb. I continue to comb sliding from scalp to end of the hair and in every direction until I don’t see any more lice on the hair comb. I did use the coconut oil remedy and put some vinegar, shampoo, olive oil and tea tree oil but I used olive oil because my coconut oil was too hard to get out of the jar. I will use it tomorrow. My granddaughter must have given it to me.
I thought I must have an allergy to something but no it was lice!

Wow it was helpful. My daughter used to scracth her head so hard I thought it was a rash. I thought it was a rash so i let it pass. But it was lice and nits! Helpful. Thanks.

So much information. Thank you so much. I hope it helps. We’ve been battling it for a month now and now I have it. We will beat this. Thank your for all this information.

Thanks so much for sharing, I’m trying this right now. We’re waiting for a couple of minutes (we picked 7 since that’s my little ones age and he enjoyed counting down with the phone in his hand – helpful tip). He keeps coughing saying the smell isn’t great but I keep reminding him that the smell is only temporary and that if this does work he won’t be scratching his sweet little head raw anymore. Crossing our fingers it works! Will be back to comment a review !

We are trying the vinegar technique right now. I hope it works. Last time we bought a $50 products but it killed everything. Yesterday my son said he thought he saw a head lice, so I spent over an hr combination thru with a lice comb. Nothing. So then today he tells me to come in the washroom, and (I had asked him to keep it if it happened again) lol and behold, there was another. This time I combed again and again, nothing.
But I saw it so, here we are. I too will post after its done. Wish us luck

Thank u very much for the information. Had these things in every hair on body for a couple years. Had no idea what they were. The exterminator said they were ants! Went thru 3 apt sprays and they only got worse. Finally 2 days ago I did the nix treatment and sprayed my bed. A heck of a lot better now. Still combing with the nit comb everyday. The little vampires are coming out onto the comb. Thank u again. I wouldn’t wish this on anyone.
