Doh! When we placed our hives, we didn't ever consider that we'd have to treat for mites! I need to treat my 6 hens for mites, but my beehives are only about 20 feet away from the chicken-run. Any suggestions for me? I've been studying up on Sevin 5% dust, Sevin spray (XLR Plus), Permethrin, and Ivermectin pour-on. I'm guessing the sevin dust would be the most risky for the bees due to it floating around in the air. And does anyone remember the ratio of linseed oil to kerosene (for the underside of the roost)? Thank you kindly.
