Hello fellow poultry keepers. I am currently battling my first Mite infestation.
One other thing that I thought worth mentioning, is how long mites can live away from chickens.
I had a coop with a bad infestation of red roost mites in in, so I just moved my chickens out to a different coop which was easer to clean.
Over a month later, there was still mites alive in the first coop.
Red mite know 3 stages.
Egg - larvea - mites.
The mite-egg can survive a long time before they turn into crawling larvea. Some say many months and once I read over a year.
The mites die in freezing cold. The eggs don’t. Every next spring you need to monitor weekly. And best twice every week when its warm and humid.
