Red mite can be frustrating because the birds may look normal during the day while thousands of mites hide in cracks around the coop. They emerge mainly at night to feed, then retreat into joints, perch ends and crevices.
Control therefore needs to focus on the housing as well as the hens.
What are red mites?
Poultry red mite are tiny external parasites that feed on blood. Unfed mites can look grey and dust-like; after feeding they appear red or dark.
British Hen Welfare Trust guidance recommends checking under perches, in nest boxes and around cracks where mites gather between feeds.
Signs in the coop
- tiny red or grey specks in cracks;
- blood smears under perches;
- clusters around perch ends and nest boxes;
- grey “dust” that moves when disturbed;
- mites collected in folded cloth or corrugated hiding traps overnight.
Signs in chickens
Heavy infestations can cause restlessness, reluctance to enter the coop, pale combs, reduced condition and, in severe cases, anaemia. Birds may appear irritated at night.
If a hen is weak, very pale, losing condition or unwell, seek veterinary advice rather than assuming environmental treatment alone is enough.
Start with a full coop inspection
Remove bedding and examine perch ends, joints, screw holes, nest-box corners and any felt or timber seams. Red mite exploit tiny spaces, so a quick surface clean is rarely enough.
Clean before treating
Remove organic debris so a control product can reach the surfaces where mites hide. Follow the instructions for your housing material and allow the coop to dry where appropriate.
Use products exactly as directed
Poultry mite products vary: powders, sprays and environmental treatments may have different instructions for use around birds, bedding or empty housing. Never assume a product intended for a coop can be applied directly to a hen.
Our Chicken Mite & Pest Control collection includes products such as Battles Poultry Red Mite Powder and environmental treatments. Read each label before use.
Repeat treatment may be needed
Eggs can survive an initial clean and hatch later, so a single treatment may not break the cycle. Follow the product’s repeat-treatment interval and continue checking the coop even after visible mites disappear.
Reduce hiding places
Keep housing in good repair. Seal unnecessary cracks where appropriate, make perches removable where possible and replace damaged porous materials that are impossible to clean effectively.
Do not rely on treating the bird alone
Because red mites spend much of their time away from the hen, the environment is central to control. Treating only feathers while leaving an infested coop untouched usually allows rapid reinfestation.
Biosecurity for new birds
Inspect new hens and equipment before bringing them into the flock. Quarantine practices and cleaning second-hand housing can reduce the chance of introducing mites.
When to get help
Persistent heavy infestations, sick birds or uncertainty about treatment safety justify advice from a poultry vet or experienced poultry professional.
Frequently Asked Questions
Can I see red mite during the day?
Sometimes, especially in heavy infestations, but they usually hide in the coop during daylight.
Where should I check first?
Start under perches, at perch ends, in nest-box joints and any dark cracks or screw holes.
Do red mites live permanently on chickens?
No. Unlike some other mites, poultry red mites spend much of their time in the environment and feed mainly at night.
Can I use household insecticide?
Only use products specifically suitable for poultry environments and exactly according to the label. Household products may be unsafe for birds or eggs.
How do I know they are gone?
Continue overnight checks for several weeks and follow the treatment cycle recommended by the product manufacturer.
