TWT:
The goal is to have bees that will groom themselves naturally like Russians are supposed to do to get rid of Varroa. Then, we won't have to treat them at all with anything ever again. My humble theory is that spraying with Sucrocide or sugar water will encourage them to get into that habit. As they are taking the Sucrocide or sugar water off of each other, they will pull off Varroa. The theory may not be correct, but it is logical.
ok let me say this and this is just me, all my hives never see any treatments at all, I have nevereven used chemicals in any way, never done sugar shakes or anything, you will not teach bee's like your post seems like, you will treat or not treat for them to live, its in the bee not you spraying something on them trying to teach them to groom more, you will not succeed teaching bee's to groom more by spraying them with anything

, best to try not treating at all and raise from them hives that live like I do and others have done!!!
