Mite season is here 🔦
As the coop warms up, red mite go from a nuisance to a plague — in warm weather their whole life cycle takes about a week, so a handful in August is thousands by October. They live in the cracks of the coop by day and crawl onto the girls at night to feed.
🔦 The torch test
Go out after dark with a torch and run it along the underside of the perch and into the joints. Wipe a white paper towel along the perch — red smears mean mites. Other giveaways: the girls refusing to roost, pale combs, restless nights, a drop in eggs, or little blood spots on the shells.
💊 Exzolt — the one we use
Exzolt is the NZ-registered red mite treatment for laying hens, and it also sorts out lice, scaly leg mite and northern fowl mite. Dead easy to give: 0.1ml on a square of bread, hand-fed one per bird — two doses, exactly 7 days apart. No mucking about with the water trough, and you know for certain every girl got her dose. It works from the inside, so every mite that bites gets dealt with, and one course gives up to 12 weeks of protection.
🦵 Crusty, raised scales on her legs? That's scaly leg mite burrowing under the scale — same treatment, same course.
🥚 And you keep eating the eggs — no egg withholding.
One 2.4ml pack treats 12 hens for the full two-dose course.
🧹 The bit nobody tells you
Treatment is only half of it — 95% of mite control is cleaning. Strip the bedding, scrape the perches, wash the coop, let it dry in the sun. Do it on day 2 of the course and the mites have nowhere to come back to.
