What causes red mite infestations in chicken coops? | arlo.® Atlas

Read time: 3 minutes

Overview

Red mite infestations in chicken coops are usually caused by a combination of warm hiding places, tiny cracks and joints in the housing, and regular access to birds at night. The mites often live in the coop rather than on the chickens themselves, so a clean-looking flock can still have a mite problem. There are several possible causes, and the main clues are often found in the housing and routine cleaning.

Things To Check

1. Check the coop at night or very early morning, when red mite are more active and easier to spot.

2. Look along perches, perch ends, corners, screw holes, joins and cracks where mites can hide.

3. Check for grey dust, small moving specks, dark staining or a pepper-like appearance around resting areas.

4. Inspect nest boxes, bedding, perch supports and any rough or damaged woodwork.

5. Look at the birds for pale combs, restlessness, reduced egg laying, reluctance to roost, or signs they are not settling well at night.

6. Check whether the coop feels warm, damp or poorly ventilated, as these conditions can make mite problems harder to manage.

7. Review how often bedding is changed and how thoroughly the house is cleaned between uses.

Common Causes

The most common cause is a coop that gives mites plenty of hiding places, especially wooden housing with cracks, joints and rough surfaces. Red mite can survive in small gaps and emerge at night to feed.

Another common factor is leftover bedding, dust and droppings building up over time. This can make it easier for mites to spread and harder for owners to spot them early.

Warm, sheltered housing can also encourage infestations to build quickly, particularly in mild weather or when coops are not cleaned deeply enough between flocks.

Less commonly, mites may be introduced on new birds, equipment, nest material or clothing after contact with another infected setup.

What To Do

Start by removing bedding, checking all cracks and cleaning the coop thoroughly so you can see where the mites are hiding. Pay close attention to perch ends, joints and nest boxes.

Wash and dry the housing regularly, replace soiled bedding, and keep the coop as dry and airy as you can. A simple routine of frequent checks is often the easiest way to catch a problem before it builds up.

If you move birds, equipment or bedding between flocks, keep that routine consistent so you can reduce the chance of bringing mites back in. It can also help to inspect the coop after any period of warmer weather or higher stocking pressure.

When To Contact A Vet

If your birds seem weak, very pale, off colour, or are not eating or drinking well, speak to a vet. Heavy mite burdens can sometimes contribute to more serious health problems, especially in young, old or already unwell birds.
