Diatomaceous Earth. You can dust them with it, sift it over the area, mix it in the feed (to control internal parasites, and give animals an overall healthier look), make a sandbox for a dust bath with it mixed in. You can paint/dip the legs in cooking oil, vaseline, etc to smother existing mites a little quicker but the DE is your moneymaker.

I can see using it on the ground and nest boxes but what about the walls and the roost. Wouldn't that need treatment also? How much do I put in the food?

Go to your vet supply and get a little bottle of VetRX. It is 100% natural and works great. Plus it is ok to you for shows and such. Much quicker than DE. Sufficates them. Just my 2-cents

I've done lots of research on the various methods of getting rid of mites--scaley leg or otherwise, from Vaseline to DE to chemical sprays & dust. What I found out I put on my chicken info site, here:

I personally favor the Adam Flea & Tick Mist With IGR (Insect Growth Regulator) spray. It does the job and KEEPS ON doing it for three months with one application. I had a little cochin hen who had a very stubborn scaley leg, the Adams spray cleared it up in one application and it hasn't come back since. It's also great for roost, nests, etc.

I like to use my little hand-held steamer machine to get in the nooks and crannies of the coop, roosts and nests first. It's totally non-toxic and kills the little buggers with high-pressure steam, which they cannot develop a resistance to. I follow it up with the Adams spray, and it works like a charm.

The Adams spray with IGR can be pricey, but since it keeps working for three months, it's a good investment.
