Signs of Red Mite in Chickens
Red mite is a small blood-feeding parasite that hides in coop cracks by day and feeds on hens at night. Watch for hens reluctant to enter the coop at dusk, pale combs and wattles, tiny grey or red specks in nest boxes and perch joints, night restlessness, and falling egg production.
How to Check a Chicken Coop for Red Mite
Checking a coop for red mite takes about ten minutes with a torch. Focus on perch ends, nest box corners, roof joints and timber cracks: lift each perch, shine the torch into the brackets, scrape joints for moving specks, and repeat after dark when mites feed.
Old, gappy coops may never be fully mite-proof, so it is worth comparing a premium coop against a cheap wooden one.
Red Mite Powder for Chickens and Spray for Coops
Powders and sprays work best as a two-part system: powder for prevention, spray for active colonies. For routine prevention, dust diatomaceous earth powder into nest boxes, perch ends and crevices, and many keepers add Red Stop mite control to drinking water, making the birds' blood unattractive to mites so they stop feeding and cannot breed. Battles Red mite powder is another good preventive.
When mites are established, reach for a dedicated killer. Nettex Red Mite Killer is a pyrethrum-based spray that treats the coop, not the chicken, with a power spray that protects for three months, while the Nettex Total Mite Kill aerosol delivers a rapid knockdown with long-lasting residual action. For really stubborn, large infestations, Perbio Choc is recommended for really stubborn, large infestations.

A Simple Prevention Routine That Works
Prevention comes down to disruption: mites thrive in dark, warm, undisturbed cracks, so remove those conditions and check often. Inspect perches and nest boxes every seven days, refresh DE powder monthly or after any deep clean, keep bedding dry and replace it regularly, seal or replace cracked timber, and treat the coop with a residual spray at the start of each season. The Alabama Cooperative Extension System's guidance on poultry red mites makes the same point: targeted action beats blanket spraying.
Here is the routine that keeps red mite from settling in.
| Task | What to do | Frequency |
|---|---|---|
| Inspect | Check perches and nest boxes | Every seven days |
| Dust | Refresh DE powder | Monthly or after a deep clean |
| Bedding | Keep dry and replace regularly | Regularly |
| Timber | Seal or replace cracked timber | As needed |
| Spray | Treat coop with residual spray | Start of each season |

Frequently Asked Questions
How can I prevent red mite in my chicken coop?
Prevention focuses on regular inspection and creating a hostile environment for the mite. Check your coop weekly, paying close attention to perch ends and nest boxes. Use a food-grade diatomaceous earth powder in nest boxes and around perches to help prevent infestation. For added protection, consider a product like Red Stop, which is added to drinking water to make birds' blood unattractive to mites. Keep your coop clean and well-ventilated to reduce hiding spots.
What is the best preventive treatment for red mite in chickens?
There is no single 'best' product, but a combination approach works well. Diatomaceous earth is a proven tactic for preventing coop infestation and is safe to use with chickens. For a proactive measure, Red Stop concentrate offers protection from red mite by adding it to drinking water, with no egg withdrawal period. For established colonies, a red mite spray for chicken coops containing permethrin, like Nettex Total Mite Kill, provides rapid knockdown and long-lasting residual action.
How do I know if my chickens have red mite?
Look for signs of red mite in chickens such as restlessness at night, pale combs, and a drop in egg production. You may also see tiny red or grey specks in the coop, particularly under perches and in nest box crevices. Check yourself by running a white cloth along the underside of perches; if it streaks red, you have a mite problem. A heavy infestation can cause anaemia and even death if left untreated.
Red mite can wipe out a season of egg production if you let it settle in. Get the right products in place before it does. Get started with Chartley Chucks and keep your flock protected all year round.
