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

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.

I’m dealing with the same problem unfortunately I have Heritage turkeys and they aren’t exactly happy to be held and dusted and they’re really big. I just spray well that be enough to knock them down. They do way better when they free range daily. I actually see a decrease in the numbers on them. I keep an ash pile and they use it often. I do feel very bad for them. I have had the buggers jump on me and it hurts when they bite. I just don’t have any anyone to help me hold them so I can dust them.

I have had to deal with demodectic mange on two of my foster dogs (which have been adopted). The veterinarian way is with Ivermectin. The mites get Ivermectin in the dog's blood when they feed. It takes time, 4- 6 weeks, but eventually they die. The downside is that the ivermectin suppresses the immune system in dogs. However it appears to stimulate the body's immune response in birds. So, while I would not use it on a dog over an extended time, it should not hurt your chickens. But, it takes time.

For my dogs with mites I found buffered Vitamin C (powder or granules) worked quickly with no ill side effects- just in case you're wondering. Vitamin C also works with chickens. It's not that your chickens are necessarily low in vitamin C, but that they aren't getting enough to ward off mites and need more. 1 to 2 weeks. Just a pinch per bird once a day if you go that route.

The people I bought my Brahmas from (who have champion birds) put garlic in the bird's food everyday to ward off mites. Garlic makes them taste bad to mites and gives the chickens' immune system a little boost. One pinch per bird per day and wait 1 to 2 weeks to see an effect. It will not kill the mites but will make them leave the birds and not come back to them. It will take about 3 weeks for the mites to die from starvation.
