Ivermectin, permethrin, diatomaceous earth not working for mite infestation!

[McChooky]

There are no cure all treatments for mites.You must know what kind of mites your chickens have. Apply treatments ever so many days prevents hatchlings from enjoying a blood meal. This will prevent any that hatch from reproducing

 

[Folly's place]

And all your birds and their coop need to be treated at the same time, not only this one hen.
Permethrin spray and dust work fine when used correctly. DE isn't worth using. Ivermectin kills mites on the bird, but not in her environment, and again, all birds in the flock need to be treated at the same time, and again in seven to ten days, at least one more time.
Her wild sparrows bring mites into the coop, an ongoing source or reinfestation. Miserable! The products work fine, it's reinfection that hurts our flock here.
