Norman has answered this so here is a small addition. I suggest you use
the OMF under all colonies and put a tray under each for a day or two in
May and see what you get. Use the multiplier and take it from there. Use
any integrated method you wish and monitor again, say, a month later.
Adjust the potency of your method(s) to suit the level found. You can
monitor the mites for damage and consider breeding from those colonies
doing most damage.

What do people say about this approach? I haven't tried it yet as I have
chickened out and have only used an annual application as one of the
herd but it is the logical conclusion to integration, which would have
to be on an individualised basis. The critical time would be late in the
year when overwhelmed colonies disperse.
