The community of honeybees in question began as a side-by-side divide (split from one of Bill's March 27 packages) with the mother queen moved over. On Aug 9 there were 0 mites on the sticky board but I found some in the drone brood so I removed all drone brood I could find. I returned on Aug 20 with Formic Pro placing 1 patty and adding a 2nd 10 days later, per label instructions for this style.
On September 14, I placed a new sticky board and 48 hours later found 64 mites had dropped!
I've ordered Hopguard 3 to install asap. Also will plan to follow up with oxalic in November.
Anyone have advice or commentary?
Larry V, how often have you seen a 64 mite drop except right after you started a new treatment? I know recommended threshholds for alcohol washes but am still learning how to interpret drops.
I'll say it's another thing pushing me to try the Single Brood Chamber approach (having that set up by the time of the mid-July dearth) b/c I feel like the brood may have been too scattered across the multiple box stack and this could present a problem for Hopguard too. The bottom box is often largely abandoned by this time of year, but I'll need to confirm this, which can be disruptive on the dearth-y days of fall.
The 2x10 day Formic approach may cause less of the disruption that leads to supersedure, though in retrospect I would not lament the loss of this productive but mite-vulnerable queen.
