I thought I was treatment free because I do not use any chemicals in my hives. In addition I live in an area where generally there are no field crops that are treated with insecticides or other adverse chemicals. I can not account for the locations that my bee travel so that is always an issue that is out of control. Today I read a research article about the contaminants that are found in commercially produced bees wax foundations. I was not surprised because I purchase a substantial amount of bees wax to make candles and I have observed the poor qaulity of some wax and recognize that some wax is from the lower brood boxes used by many commercial beekeepers and others, and it is this wax that probably finds its way into the foundations made by the major companies that sell hives and related beekeeping material. So although I may not desire to treat my hives with chemicals it is very possible the so called store bought frames and foundations are already contaminated and the honey I produce and thought was clean of chemicals could e exposed to contaminated foundation bees wax. This is like a viscous cycle where it seems impossible to keep clean hives. From now on I will the folks that I sell honey to that I do not use any chemicals in my hives, but that does not mean my hives are chemical free. I would appreciate your thoughts on this matter.
