This may be a sensitive topic for some, please be aware that I am not trying to offend anyone. These questions are always in mind so I thought I'd ask. I am under the impression that comb should be changed out every 3 to 5 years, preferably 3 due to the possibility of the internal explosion of pests and or disease. When purchasing nucs, is this not a form of a comb change out for the source to maintain health? I'm curious if anyone has a routine to address potential health hazards when buying a nuc after transferring to another location since we're buying anothers comb changes? Besides the hopeful rapid growth of a nuc, in your eyes, what are the benefits of purchasing packaged bees? Does anyone prefer packages over nucs and may I ask why? Does anyone dust for mites before installation or what is your standard method?
