Red mite is one of the most frustrating problems for backyard chicken keepers because the mites often hide in the coop during the day and feed on hens at night. A flock can therefore be irritated before the keeper sees obvious numbers of mites.
The British Hen Welfare Trust describes red mites as tiny yellow-brown mites that become red after feeding. They tend to hide in cracks, crevices and around perches, which is why checking the housing is just as important as checking the birds.
Common signs of a red mite problem
Possible signs include increased scratching, feather pecking, reluctance to enter the coop, changes in perching behaviour and pale combs or wattles in more serious cases. None of these signs is unique to red mite, so avoid assuming every itchy or unsettled hen has the same cause.
If a hen appears weak, pale, unwell or persistently uncomfortable, veterinary advice is appropriate.
Where to look for red mites
Red mites prefer dark, sheltered spaces. Check underneath and at the ends of perches, inside joins, under removable trays, around nest boxes and in small cracks in the structure.
The British Hen Welfare Trust suggests checking hidden areas carefully because mites may be much easier to find in the housing than on the hens during daylight hours.
Why cleaning the coop matters
Managing red mite usually involves the environment as well as the birds. Remove soiled bedding and debris so cracks, joints and surfaces can be inspected properly. Follow the directions on any cleaning or mite-control product closely.
You can browse our Chicken Coop Care collection for coop-cleaning and ground-care products, and our Chicken Mite & Pest Control collection for products specifically intended for poultry pest management.
Use mite-control products exactly as labelled
This is particularly important with insecticides, powders, sprays and smoke products. Some are intended for the housing only, while others may have different directions. Never assume a coop treatment is suitable for direct application to a bird.
Check whether hens, eggs, food or water need to be removed during treatment and observe any stated re-entry, ventilation or withdrawal instructions. The product label should take priority over general advice online.
Do not forget feeders, drinkers and accessories
A thorough cleaning routine should include removable equipment where appropriate. Feeders and drinkers should be cleaned regularly anyway, but during a pest problem it is especially important not to overlook nearby surfaces and equipment.
Our Chicken Feeders & Drinkers collection includes practical replacements if old equipment has become difficult to keep clean.
Check second-hand housing carefully
The British Hen Welfare Trust notes that mites can be introduced with second-hand equipment or new birds. Used coops, perches and accessories should therefore be inspected and cleaned before being introduced to the flock area.
Regular checks are useful even when you have never had a known infestation. Catching a small problem is usually easier than dealing with a heavily populated coop.
What about the hens themselves?
Observe each hen for signs of irritation, feather damage, poor condition or unusual behaviour. If there are wounds, marked anaemia, weakness or a bird is not eating or drinking normally, contact a poultry-experienced vet.
For basic poultry-care products, visit Chicken Health & First Aid. These products support everyday care but are not a replacement for veterinary diagnosis or treatment.
Create a repeatable prevention routine
A useful routine is to inspect perch ends and coop crevices, keep bedding dry, clean the housing regularly and avoid allowing dirt to build up in inaccessible areas. Housing that is easy to dismantle or clean can make routine checks much simpler.
If you are reviewing the housing itself, our Chicken Coops & Runs collection brings together the current housing options available through Wellbeing Pets.
Frequently Asked Questions
Do red mites live on chickens all day?
They commonly hide in the coop during the day and feed on birds at night, which is why daytime inspection of cracks and perches is important.
Can red mite make hens unwell?
Heavy infestations can cause significant irritation and blood loss, potentially leading to anaemia. Seek veterinary advice if a hen appears weak, pale or unwell.
Should I treat the chicken or the coop?
That depends on the product and the problem. Some treatments are intended for housing only. Always follow the manufacturer’s label and seek professional advice if you are unsure.
How often should I check for red mite?
Build checks into normal coop cleaning, and inspect more closely if hens become reluctant to roost, start scratching more or you notice signs around perch ends and crevices.
