Mites and poultry lice are a natural part of every backyard- they travel on birds, rodents and other animals, so when your chickens become infested, it doesn’t mean you’re not keeping a clean coop, it simply means your chickens enjoy the Great Outdoors! Being able to identify each type external parasite is not important, but the ability to recognize the signs and symptoms of an infestation and how to treat them is.

The following information may make you itch, but not knowing how to treat mites and lice effectively can have devastating consequences for chickens.
Dirty vent feathers demand a closer look.
Dirty vent feathers demand a closer look.Some of the common signs of any type of mite or lice infestation in a chicken are: dirty-looking vent feathers, decreased activity or listlessness, a pale comb, changes in appetite, a drop in egg production, weight loss, feather-pulling, bald spots, redness or scabs on the skin, dull, ragged-looking feathers, crawling bugs on a chicken’s skin or nits on feathers.
COMMON EXTERNAL PARASITES in CHICKENS:
The two most common categories of external parasites in chickens are mites and poultry lice. Poultry lice are NOT the same as human head lice and people cannot contract lice from chickens.
MITES
Northern fowl mites and Red Roost Mites are two of the most common poultry mites. These tiny, eight-legged beasts can live both on the chicken and in the coop. Red roost mites are partial to cracks and crevices in wood, roosts and inside nesting boxes.
Mites can be grey, dark brown or reddish in color and can often be seen along feather shafts and underneath roosts after dark. Red roost mites are active at night when they venture out to leech blood from chickens. With its moist, rich blood supply, the vent area is a favorite feeding ground of mites.

Mites on feather shafts and chicken’s skin
Typical signs of a mite infestation are scabs near the vent, eggs on the feathers and feather shafts and a light colored bird’s feathers may appear dirty in spots where the mites have left droppings and debris. A heavy mite infestation can lead to anemia and death of a chicken. Mites will bite humans, causing minor irritation in the affected area (and an urgent desire to take a gasoline shower).

SCALY LEG MITES
Another common mite is the scaly leg mite, (Knemidokoptes mutans) which I discuss in detail here.
POULTRY LICE
Poultry lice are fast-moving, 6 legged, flat insects with round heads that live only on the chicken and its feathers. They are beige or straw colored and are typically found at the base of feather shafts near the vent. Poultry lice feed on dead skin and other debris such as feather quill casings. When parting the feathers near the vent to inspect for parasites, they can be seen briefly as they run away. The eggs laid by the female are seen at the bases of feather shafts.
New poultry lice infestation detected early. Note the absence of nits or debris on the feather shafts.

PREVENTION
Mites and lice are most commonly brought into chicken yards by wildlife, especially by wild birds. The use of best biosecurity practices, regular inspections, and vigilant observation will limit the damage they inflict.
- Clean coops regularly, disposing of loose feathers that can carry hatching eggs (nits).
- Limit visits from fellow poultry-keepers who can transport the creepy crawlies on their clothes, footwear or equipment, (vehicles, shared farm equipment, etc.).
- Do not attract wildlife to the chicken yard with the use of wild bird feeders.
- Secure chicken feed to prevent parasite and disease-carrying wildlife from visiting regularly.
- Do not introduce chickens into an existing flock that you have not raised as baby chicks from an NPIP certified hatchery.
- Provide adequate dusting areas for chickens to care for their own skin and feather health.
Mites and lice will not be repelled by herbs of any kind.
Never use food grade diatomaceous earth with chickens in any way. It is not an effective insecticide and is hazardous to hen health as well as being a known carcinogen in humans.

I NEVER use and do not recommend food grade diatomaceous earth for any purpose with chickens. A dust bath should never include food grade diatomaceous earth nor any other additive! Good sanitation practices, frequent flock inspections and providing ample access to sand for dust bathing are sufficient preventative measures without exposing the chickens or humans to the ever-present exposure to a carcinogenic respiratory hazard.

LICE & MITES TREATMENT
When lice or mites are found on one bird, the entire flock and coop must be treated. There are many different products available to eradicate mites and lice with varying degrees of effectiveness and safety, among them are:
- Elector® PSP
- Davis Pure Planet Poultry Spray
- Garden & Poultry Dust with Permethrin
- Prozap Garden & Poultry Dust
- Dog flea dips, flea shampoos (for temporary relief only)
**Treatment for lice and mites with most products must be repeated twice after the initial application in 7 day increments, in order to kill the eggs (nits) that had not hatched at the time of the previous treatments. This does not apply to Elector PSP, which is a one time application.**
Rotate treatment products to prevent the development of resistance by parasites (this does not apply to Elector PSP). With all methods except Elector PSP, the entire coop must be cleaned out and treated with particular attention paid to nests and roosts. With Elector PSP, the building can be treated directly with the birds inside it, but the presence of parasites is a good reason to clean out the coop anyway.
8 oz Elector PSP bottle
Elector PSP can be purchased in 8 oz bottles online for approximately $160.00. I offer Elector PSP in 9 ml bottles for small flocks HERE.
By far, my preferred treatment for lice and mites is poultry veterinarian recommended Elector® PSP . The active ingredient is Spinosad , a product of the fermentation of Saccharopolyspora bacteria. Elector PSP has NO EGG withdrawal period!
Spray in cleaned, empty coop and on birds at the rate of 9 ml per gallon of water. Always mix a fresh batch for each use.”Spinosad (fermentation product of Saccharopolyspora, a type of bacteria). Single use controls all stages of mites. Also kills flies, beetles, agricultural insect pests. Can be used directly on laying hens and to spray buildings.”* Elector PSP can be purchased HERE.
This video shows Mr. Chicken Chick & I treating three of my hens for mites with Elector PSP.
This video explains HOW Elector PSP works. Read more information about Elector PSP HERE.
ABOUT Elector PSP
Poultry veterinarian recommended Elector PSP is the most effective, safest, easiest solution to eradicating mites and lice in your flock with NO egg WITHDRAWAL period! Elector is safe for humans and your pet chickens. Due to its multiple mechanisms of action, mites and lice do not develop resistance to it. Elector PSP, in the spinosyn class of insecticides, acts as both a larvicide and an adulticide, killing adults and their nits after ONE application when used properly.
This terrific video explains HOW Elector PSP works. Given the mechanisms of action as described in the video, it can take a day or two for full effectiveness.
TO USE Elector PSP:
Treating birds after dark when they have gone to roost is the easiest way to handle the entire flock while minimizing stress and without having to chase anyone. It’s best to tackle the job with a partner.
Dilute 9 ml of Elector PSP in one gallon of water. Shake well before and frequently during use. Add solution to a spray bottle to apply to all flock members, paying particular attention to the feathers and skin around the vents and crests of crested breeds.
If treating for red roost mites, spray the coop, paying particular attention to crevices.
Prepare solution fresh for every application. Follow manufacturer’s instructions for disposal of unused portion.

If using a dust product, while wearing a respirator, gloves, and protective eyewear, dust underneath the wings and vent area of each bird sparingly but thoroughly.

how often should I use the elector PSP? I’m pretty sure my 3 girls may have mites I just cleaned their coop and they dust bathe but? So when I get this $$stuff, how often do I need to spray? would I do it on a routine basis? I’m introducing 3 young girls into the flock, should I spray them as well
ONLY when there is a mite infestation.
What do you use to actually spray this mixture onto the hens ? I read about the stuff on the link and it says mix with 10 gallons water !!! I don’t have a ten gallon container!!!!!!!
You can make one gallon with 2 teaspoons of Elector PSP (a half gallon with one teaspoon, etc). I use a regular hand sprayer of the type you would put cleaning products in or water to spray your houseplants.
I am wondering if I should be treating my yard as my hens free range during the day and I notice the eggs on one hens butt yesterday. I ordered elector psp last night and in the meantime I am using permethrin spray on the run and coop and birds till it arrives. But now I’m wondering if I should keep them in and treat the yard with DE or lime?
NEVER use DE or lime! They are both dangerous and unnecessary in backyard flocks
Some of my chickens, especially my frizzle rooster, are missing the actual feathery part of the feather, and just have the shafts. Is that a sign of mites?
No, that is a sign of poor breeding. See this article for more information about that. https://the-chicken-chick.com/frizzle-feathered-chickens-divas-of/
I am clicking on the link for the elector psp and keep getting a whoops error. Where else can you purchase ?
Just do a Google search- it’s sold lots of places.
I’m in California and it does not appear anywhere on a Tractor Supply site or Amazon. What state do I have to travel to in order to get this? Thanks!
Are you asking about the Elector PSP? You can order it online at Valley Vet, among other places.
Thank you!
