Treating for varroa is no hassle, many different ways of doing it. Some more effective than others and some more labour intensive than others, depends on your ethical view point. These days I stick miticide strips in each hive, takes about 30 minutes and remove 6 weeks later....another 30 minutes.
I check drop counts a few months afterwards and if any seem high they get vaped with Oxalic Acid. With a sublimox it's about 1 minute per hive.
