Hi...say, how much tea tree per qt jar? Please...I have a population explosion of varroa.I have never used grease patties. I understand that if you add some essential oils to the mix they can be useful against varroa, but only for bees coming in direct contact. I prefer to add tea tree oil to the syrup. The essential oil ends up in their food supply and apparently disrupts the mite`s reproduction. But I don`t do this while the bees are collecting surplus honey.
Putting crisco in a hive just doesn`t sound right to me. Bees eating grease? I don`t care how much sugar is in the patties... they`re still eating grease and I don`t think that does them any good. Just my opinion.
