You missed the point. I may think that mites are coming from somebody else's hives, but I can't prove this if:

A) I don't know where they are. You and I have no idea how many hives actually live in our own neighborhood. How could we?

B) No way to identify mites. One can label bees, which was done to demonstrate that those bees were not abandoning their hives and invading others.

In other words, we all think this, but nobody has caught them in the act. The vector may in fact lie elsewhere. It is quite clear that crashing hives lose a lot of bees in a hurry and these are likely covered with mites. Somehow those mites end up in my hives. I would like to know how.
