80% of mites, not worth bothering with, also its a trickle, Mmmmmm
My only worry with these new mixes with added Snake oil and Fairy dust, is that it may lead to the introduction of more regulations to enforce we dont use the pure form of Oxalic acid, wood bleach as we know it here. They do sell Apibioxal in France now, same as the uk, but no one I've heard of uses it.
At the moment they turn a blind eye because it seems the powers that be, realise it works and is better we have a good, economical alternative than further decline in the honey bee population.
I also cant help but think of damage to Queens if your trickling two different acids over bees and their colony. Formic acid on its own is enough to bleach the grass in front of your hives,
And I quote" VarroMed is intended to be used as part of an integrated Varroa control programme, which includes not only treatment with medicines but also non-chemical techniques like queen trapping or drone brood removal"
Not in my apiaries at any time thank you!!
I rest my case!
