With alot of people buying packages and the general consensus being that they come loaded with mites, what are all of your thoughts on treating the bees while still in the package? This was a topic being discussed in our journeyman beekeeper meeting last night. Some were saying they were going to use a Hopguard strip which I don't feel will work well unless you intend to leave them in the shipping package for a while. Other thoughts are powder sugar dusting. My suggestion was oxalic.
It would seem like a good time to wipe out the mites while there is no brood.
