An easy way is using Thymol strips.

Put a strip of Thymol in the hive, this is a natural ingredient of honey and kills Varroa and Tracheal mites. The strip has the right amount and I never had a smell or taste in my honey.
Place a second strip two weeks later without removing the first on. It’s much easier than formic, not danger for beekeeper and bees, and has a better result.
Another good thing…for organic beekeepers, it saves you the whole year work fogging with FGMO and Thymol.

People using powdered sugar say you need to use it every week for three weeks.
