Re: treatment free beekeeping - the risks
i'll give it one more shot pedro, i'm still having fun here. and let me reiterate that my purpose for starting this thread was to give up and coming beekeepers the 'other side' of the 'treatment free' approach.
again, the problem with your scenario is that i don't know of any way my bees are going to be contaminated by my neighbor's bees unless my neighbor's bees get so sick and weak that they succumb to robbing by my bees.
you say that you are sure there are other ways, but are you sure? when you find out what they are, let me know and we might be able to pursue that line of argument.
