Re: something to think about
The premise in the first post is correct. Any beekeeper who allows a hive to die of disease such as AFB, mites, or whatever, or get close enough to death that it gets robbed, will spread the infection to the hives that do the robbing.
Having said that, a hive that died of mites, will be mite free just a few days after the bees die. In a lab experiment, mites in a petri dish with no food lived a maximum of 4 days.
