I don't have any other hives within 5 miles of this location. They are in a residential neighborhood, not far from city center of a small town of about 50,000 population. There are 2 large cemeteries within a 1/2 mile, with lots of grass/clover/ornamental trees/shurbs and plantings, etc. So I would think there would be forage. There no wax moths or SHB in evidence. I'm thinking of taking away their capped honey. Maybe if they don't have stores, it will motivate them to do something. There are a couple of frames with small patterns of brood. Last inspection, I didn't notice any eggs, but a smattering of uncapped and capped brood. I'm very puzzled and worried about losing them.
