Re: Something needs to change - looking for suggestions
My best guess is that there are a few things going on. Reduction of mites through the brood interruption (Older mites missing their last reproduction opportunity before they die). Poor breeding conditions for the remaining mites due to over crowding in the new queens first batch of brood, and a young vigorous queen that out breeds the mites. This becomes important at the July brood break as it changes the dynamics of the colony from an established colony that will wind down brood production and population to a building population. We shouldn't underestimate the power of a new queen.
