Chicken Mites, How to Identify and Get Rid of Them
Three main mites attack backyard chickens: red mites (live in the coop), northern fowl mites (live on the bird), and scaly leg mites (under leg scales). Treatment differs for each.

1. Red mites (Dermanyssus gallinae)
Live in coop cracks by day, feed on birds at night. Cause anemia, pale combs, and night-time restlessness.
2. Northern fowl mites
Live on the bird 24/7, especially around the vent. Look like moving black pepper.
3. Scaly leg mites
Burrow under leg scales. See dedicated guide.
What to check first
- At night with a flashlight, check perch undersides for moving red specks.
- Part feathers near the vent, see crawling pests or dark egg clusters at feather bases?
- Pale combs and weight loss in the flock?
- Hens refusing to roost or seeming restless at night?
Home care that works
- Treat birds with permethrin dust (Manna Pro Poultry Protector) under wings and around vent. Repeat in 7-10 days.
- Strip and burn old bedding; scrub coop with hot soapy water.
- Treat coop cracks, perches, and nest boxes with permethrin spray.
- Add a generous diatomaceous earth dust bath for the flock.
- Repeat coop treatment after 7 days to catch hatching mites.
Call a vet if
- Severe anemia (very pale comb, weakness, collapse).
- Mite infestation that returns after 2 full treatment cycles.
Frequently asked questions
Does diatomaceous earth kill chicken mites?
Food-grade DE helps in dust baths and dry coop crevices, but it's not strong enough to clear an active infestation alone. Use permethrin for the kill, DE for prevention.
How fast do mites multiply?
Red mites complete a life cycle in 7-10 days in warm weather, that's why a single treatment never works.

Clearing mites from birds and the coop
Mites are tiny parasites that feed on blood or skin. The two most common are northern fowl mites, which live on the bird, and red mites, which hide in the coop by day and feed at night. Treating only the birds or only the coop is the most common reason mites come back.
Confirm what you have
- Check birds at night. Part feathers around the vent and under the wings.
- Wipe a white paper towel along the underside of the roost after dark. Red or gray smears mean red mites.
- Look for dirty-looking feathers near the vent, scabs and pale combs.
- Check nest boxes and cracks in wood.
Treatment plan
- Treat every bird, not just the worst.
- Use only products labeled for poultry, and follow the label for how much and how often.
- Repeat treatment as the label says. Mite eggs hatch after the first round.
- Strip out bedding and nest material and bag it.
- Scrub roosts and cracks, and treat the coop with a labeled product.
Many keepers add wood ash or a dust bath area. That helps birds keep mites down, but it does not clear an infestation on its own.
Look-alikes
Lice are larger, move fast and leave egg clusters at the feather base. Scaly leg mites live under leg scales and need different care. Feather loss from molt or pecking has no crawling pests.
When to call a vet
Call if birds are pale, weak or losing weight, since heavy mites can cause anemia and death, especially in chicks and broody hens.
Eggs and people
Check the product label or ask a vet about eating eggs during treatment. Bird mites can bite people but do not live on us. Wash and change clothes after coop work. The mites and lice page has more.
Common questions about chicken mites
Can chicken mites live in my house?
They may bite briefly but need birds to survive and reproduce.
How often should I check for mites?
Once every week or two, and always before adding new birds.
Does diatomaceous earth kill mites?
Results are mixed and dust can irritate lungs. Use labeled products for a real infestation.
