Mites on Chickens

 On December 27th my two hens Lois and Cleo got into an argument, that ended with blood dripping all down poor Lois’ face from a nasty bite on her comb. I took her inside, stood her up in front of the kitchen sink and got to work cleaning the blood of her head. I used a soft towel dipped in warm water, and once most of the blood was gone and the wound had stopped bleeding I applied a layer of Nature’s Sunshine Silver Shield to protect the wound from any bacteria or infection and was set to take her back out to the coop. She had been such a good girl, I thought I would reward her with a piece of shredded carrot before she went back, and that’s when I noticed it. Little tiny specks crawling all over my hand, and my arms, and all over my sweater. I’m itchy just thinking about it!

Needless to say Lois was rushed back outside and I went to work DE-ing myself, my kitchen, and anything else that came in my way. (I lightly dusted her too before I stuck her on the roost with her sisters).

We have mites. Northern fowl mites to be exact.

Since we had not introduced any new birds to our flock my guess is that they came in on the wild birds, that have been making a habit of eating out of the goat food bowls before we started on our commotion free feeding system. When the goats were running back and forth between dishes little chickadees would fly down and grab some of their grain. I had thought it was cute at the time. Now I’m like “chickadee be gone!” I have since let my bird feeders hang empty, and with tying the goats to eat, the birds have stayed away. I love watching the wild birds so the bird feeder on the other side of the house and well away from the barn will probably get a refill one of these days.

But I digress.


That night I read up on everything I could on mites and chickens, and what to do about it. The next day I went to work cleaning and spraying the barn.

We are very alternative in our health and prevention practices, and aim to use natural whenever possible. Most people think that natural always means safe, but you do need to respect some natural solutions as well.

After a lot of reading and research as well as listening to my own intuition I armed myself with the following:

    1. Diatomaceous Earth. To be clear I am talking about the food grade D.E. It is a fine white powder that is made up of hard shelled algae that has been fossilized. These microscopic fossilized pieces of algae are very sharp, and scratch and dry up insects when they come in contact with the powder.
      • A Few Warnings:
        • Be sure to always use food grade. You do not want the grey powder that is used for swimming pools
        • Do not breath it in! Your lungs are soft and spongy, a prime location for D.E. to do some damage. A face mask is recommended.
        • D.E. will work on good bugs and bad bugs, so be careful where and how you use it.
        • D.E. looses it’s effectiveness when it gets wet, so if you powder your chickens and they go out and stand in the rain then you will need to powder them again once they dry off
    2. Garlic. I love garlic. It can be used for just about anything, both externally and internally.
    3. Essential Oils (for the Chickens) – Lavender, Pine, Peppermint, and Lemon.
      • There isn’t a lot of research on essential oils with chickens. I decided to go with ones from plants that the chickens would naturally eat. Lemon was the exception, as some people say citrus is not good for chickens. I only used a little bit of lemon but decided to use it because of its insect repelling qualities.
      • Chickens preen and clean their feathers with their mouths so you want to be sure to use oils (or anything for that matter) that are non toxic.
      • Also please note that these are therapeutic grade essential oils and not fragrance oils.
    4. Essential Oils (for the coop) – Peppermint, Eucalyptus Citriodora, a blend called Purify, and a blend called Bug Off. (I use Native American Nutritionals Essential Oils. They are organic, high quality and aren’t multilevel marketing. I get no compensation for recommending them, I just really like them and think they are a great alternative to the more popular MLM brands.)

Life As I Know It

First I cleaned out the barn (even though we have goats on one side and chickens on the other I still had to do the entire thing. The mites could still be hiding in the goat side bedding). We had been doing the deep litter method to help protect our livestock from the harsh Canadian Winter elements. But desperate times call for desperate measures, so out came the bedding. I then sprinkled DE on the floor, and in any cracks in the boards inside the barn (beams, walls, etc), and laid down fresh bedding. I sprinkled the bedding with garlic powder then I put drops of straight essential oils in the four corners of the coop, around the doorway, and in the bedding in the nesting boxes. I also rubbed it onto the roosts. I repeat this every other day. (These would be the oils in Section D above)

 Lastly I sprayed the birds with a E.O. and garlic juice mixture. When spraying chickens for mites be sure to spray the vent extra well, and under the wings. Hubby helped me with this, and by the third day they knew what to do (bum, arm pit, arm pit, overall spray, rub it in, you’re free to go), and I was able to do all 8 hens myself.

* To make it a little easier, especially if your chickens are not tame like ours, do it at night or in a dark spot. We took one hen at a time into the goat pen (because it has a hook so you can close the door from the inside, the chicken side door does not), and closed the door so it was relatively dark when we sprayed them. This caused less stress for all of us, and less flap from them.

Mites can live for 4-5 days and lay 100,000 eggs during that period. 100,000!!! That is liable to get out of control very quickly! We were lucky to have caught it relatively early, as there wasn’t a lot of egg deposits built up in their feathers at that point, nor where they showing any outward signs of having a mite infection. Even if it looks like you are winning be sure to keep spraying for at least 3 weeks to make sure you have killed the laying cycle.


Besides actually seeing the little boogers crawling on your chickens here’s what to look for:

  • Feathers near the vent look matted or crusty (mites poop a lot, and the build up will make the feathers look kind of drab)
  • Tail feathers look chewed (this was a sign we missed because we have one goat who likes to eat chicken feathers. It is still a bit of a mystery if it were mites or Phoebe that caused a couple of our poor hens to have sad looking tail feathers. It wasn’t all of our hens that looked this way so we still think Phoebe. Some girls don’t get out of the way fast enough!)
  • Decreased egg production
  • Loss of feathers
  • Itching/Scratching
  • Chickens seem off or sad
  • Roosters will have decreased fertility
  • Mites crawling on your hands when you collect the eggs (will be on the eggs too)
  • Egg deposits at the base of the feathers near the chicken’s skin


Here is the recipe for the E.O. and garlic juice mixture I used:

 1 oz of garlic juice – I bought a bunch of garlic and ran them through my juicer. My house smelled like garlic for days, but it was a cheaper and doable route for me.

12 drops lavender essential oil

12 drops pine essential oil

12 drops peppermint essential oil

5 drops lemon essential oil

1/3 cup Olive Oil

1 1/4 cups of water

Mix all together in a spray bottle, and shake well before spraying chickens. You can also use this as a spray for the entire coop if you prefer to go that route, however I didn’t find it to be as effective by itself (without putting the other E.O.s in the coops)


A few cautions with this:

  • It stings like no other if you get it in your eyes (dang chicken flapped right as I sprayed)
  • Wear a “barn coat” or washable clothing. I just wore my coat because it is freezing here and I only have one coat (dry clean only of course). I’m scaring away vampires now let me tell you!
  • Your Hubby may have concerns over why you are (and I quote) “marinating them”

Within 24 hours the mites that we saw crawling on their little behinds had decreased by half.

I also mixed a bunch of garlic powder into their feed, and put a couple of cloves in their water.

After a week the temperature dipped too low here for us to spray them without the risk of frost bite or hypothermia. (We’re talking minus 20 Celsius as a day time high). I’ve continued to put E.O.s in the coop every other day, really concentrating on the nesting boxes.  The mites on the girls themselves continued to decrease and yesterday when I checked them I saw no mites on the majority of them. (We have a few that had them really bad, my guess is they’re the ones with the weakest immune system, and they were still carrying a few).

We did dust the girls once with a D.E. and garlic powder mixture that I put in the toe part of an old pantyhose (for easy dusting). I did not find this to be as effective, and had a hard time trying to keep the hens head away from the dust puffs (she shouldn’t be breathing in the D.E. either).


To help prevent the mites from coming back we have done the following:

  1. Put down a layer of D.E. when we clean out the barn (once a week we clean the entire thing out)
  2. Continue with the essential oils in the coop once per week (or just use the Hen spray and spray nesting boxes, roosts, and around the doorway. This has worked well as a preventative.)
  3. Garlic powder in their food (you can also put cloves in their water) to help prevent internal parasites, and external ones (external parasites like mites and lice don’t like the taste of garlic)
  4. Making sure they always have somewhere to dust bathe. Dust bathing is the chicken’s number one defense against mites, but when you’re buried in 2 feet of snow and everything is frozen solid it is hard for the girls to find somewhere to go. I put a box of sand in their coop (which they didn’t touch). We also dump the ashes from the wood stove in a corner of the paddock for them. Their favourite spot though is in the wood shavings in the goat pen.
  5. Dried mint, rosemary and lavender in the nesting boxes.

Update (April 2015): The E.O.s in the coop really helped to keep the mites at bay, as well as consistent cleaning, however because we did not spray the chickens themselves (due to extreme cold) the mites were still present. Now that the weather has warmed up a bit I have been spraying the chickens daily again, and after the second day of spraying them I only found 2 mites total on our worst infected hen.  Be sure to consistently keep up with the coop and the girls for a minimum of 3 weeks to kill off any larva.

Through early detection, a lot of work, prayer, and natural solutions we have been able to take care of our mite problem without the use of harsh chemicals that could cause problems for the environment, our hens, and ourselves.


And amen.



One thought on “Mites on Chickens

  1. Thanks April,
    I can see the white mites flying around in their yard. I am totally for a natural solution as I also have bees.
    I will be trying your EO with garlic juice as soon as I get all the ingredients. As a quick solution I will try dishwasher with water spray in the coop and around.
    I use DE on their feathers but got nothing yet for their heads.
