I apologize if this has been answered before. I tried searching and didn't get the results I was looking for.

I have seen some information on the web of people using tea tree oil in sugar syrup to help with varroa mites. I am having a hard time finding a recipe with an actual quantity of how much tea tree oil. Does anyone have a syrup recipe with a quantity?

I found the excerpt below and makes me wonder if it should be used in this manner at all. Has anyone here used it long term? Did the hive do well longterm, i.e., was the hive strong the following year, honey production, did they winter well?

According to the American Cancer Society: "Tea tree oil is toxic when swallowed. It has been reported to cause drowsiness, confusion, hallucinations, coma, unsteadiness, weakness, vomiting, diarrhea, stomach upset, blood cell abnormalities, and severe rashes. It should be kept away from pets and children."[22]
