We are so restricted here! I got rid of mites with de (I know some people say it doesn't work but as someone who has pool operator courses, I have researched the cleaning power of micro-exoskeletons) It's unfortunate the government is so restrictive when we can't even find a vet to see our animals!I can't get Sevin dust in Canada. We can't get a lot of things here, even medicine. I order what I can get from the US. We have no vets available in my area who will deal with chickens either. I am hoping with deep winter coming i can get a handle on the mites. It is pretty much the roosters that get it worse. I had read somewhere about it usually starting with them. I will just keep cleaning, spraying and treating them as best as I can, regular. I am now thinking of doing the weekly garlic juice and water spray on the chickens, weekly and then like once a month. And do the Front line every 3 months after that.
