Mites and lice are among the most common problems in backyard flocks. They cause itching, feather damage, stress and, in severe cases, anemia and death. Many owners don’t notice them until infestations are heavy. Here’s how to check for mites and lice in chickens and get rid of them.
Quick Answer: Check around the vent, under the wings and along the feather shafts. Lice are straw-colored insects that crawl on the skin and lay egg clusters at the base of feathers. Northern fowl mites live on birds; red mites hide in the coop and feed at night. Treat both birds and coop with products labeled for poultry, and repeat treatment to catch new hatchlings.
Mites vs. Lice
| Feature | Lice | Northern fowl mites | Red (roost) mites |
|---|---|---|---|
| Size | Small, visible | Tiny | Tiny |
| Color | Straw or tan | Dark red to black | Gray, red after feeding |
| Location | On bird | On bird, around vent | Hide in coop cracks by day |
| Feeding | Skin and feathers | Blood | Blood at night |
| Eggs | Clusters at feather base | Around vent feathers | In coop cracks |
Signs of an Infestation
- Feather loss, especially around the vent and under wings
- Dirty, scabby skin around the vent
- Pale comb and wattles (anemia)
- Drop in egg production
- Restlessness, preening and scratching
- Hens refusing to roost (red mites)
- Specks of “pepper” or gray dust on roosts
How to Check Your Chickens
- Check at night with a flashlight, when birds are calm on the roost.
- Part the feathers around the vent and under each wing.
- Look for moving insects, clusters of eggs at the feather base and scabby skin.
- For red mites, wipe the underside of roost bars with a white paper towel. Red smears mean mites.
Check every bird. Parasites spread quickly.
The Poultry Extension describes external parasites like these as common in small flocks.
How to Treat Mites and Lice
1. Treat the birds
- Use a poultry-labeled product approved for your birds. Follow label directions exactly.
- Pay close attention to egg withdrawal times. Some products require discarding eggs.
- Ask a vet about options if you’re unsure. Some treatments require a prescription.
2. Treat the coop
- Remove all bedding and nesting material.
- Scrub roosts, nest boxes and walls.
- Treat cracks and crevices with a poultry-safe product, especially for red mites.
- Let everything dry before adding fresh bedding.
3. Repeat
Most products don’t kill eggs. Repeat treatment as the label directs, often after 7 to 10 days, to catch newly hatched parasites.
About Diatomaceous Earth and Natural Remedies
Some keepers use food-grade diatomaceous earth (DE) in dust baths. Evidence is mixed, and the fine dust can irritate lungs in both birds and people. It shouldn’t replace proven treatments in an active infestation.
Preventing Mites and Lice
- Quarantine new birds for at least 30 days and check them for parasites.
- Provide a dust bath area with dry soil or sand.
- Keep the coop clean and change bedding regularly.
- Check birds monthly.
- Limit contact with wild birds, which can carry parasites.
- Seal cracks in wooden coops where red mites hide.
When to Call a Vet
Call a vet who treats poultry if:
- Birds are pale, weak or dying
- Infestations keep returning
- You’re unsure which product is safe for laying hens

Frequently Asked Questions
Can chicken mites live on people?
Poultry mites may bite people but don’t usually live on humans long term.
Can I eat eggs during treatment?
It depends on the product. Always follow egg withdrawal guidance on the label or from your vet.
Do mites cause chickens to stop laying?
Yes. Heavy infestations stress hens and reduce laying. See why chickens stop laying eggs.
How long does it take to get rid of mites?
Usually several weeks, with repeated treatment of birds and coop.
Are some breeds more prone to lice?
Breeds with dense, fluffy feathers, like Silkies and Cochins, can hide parasites more easily.
Can mites survive in an empty coop?
Red mites can survive for months without feeding. Thorough cleaning and treatment are important.
Do roosters get mites too?
Yes. Check and treat every bird in the flock.
Can wild birds bring mites to my flock?
Yes. Wild birds that roost near the coop or share feed can carry mites and lice. Keep feeders covered and block access to the coop.
Should I treat new birds before adding them?
Check them closely during quarantine and treat if you find parasites before they join the flock.
Will a dust bath alone get rid of lice?
Dust bathing helps chickens manage parasites, but an active infestation usually needs a proper treatment.
