my thought's on fogging Bees

most people that keep bees will have heard of varroa, and the many ways of dealing with them, I had always been a let nature takes it's course type keeper, doing no varroa control, but since starting the secret bee garden, I'd rather do something than nothing, using pesticides daily as a pest controller I'm against using any type of chemical on my bees, so having watched a few youtube clips from the fat bee man, I decided to go with using a mineral oil that's vapourised and then put through the hive, this then coats the varroa which suffocates them.

it seems an easy method of control, so if it works I'm happy,
