Absolutely the only "jewelry" I own. Non-functional baubles don't appeal to me. I almost bought this used watch (~$16,000 off the suggested list price was tempting) but then I discovered that it wouldn't do square roots, so I crossed it off my list.

Not necessary. The bees do not survive the trip into the innards of the Dyson. A little research shows why.

"The Dyson vacuum’s outer cyclone rotates at 200 mph, removing debris and most of the dust while an inner cyclone rotating at 924 mph drives fine dust and even particles of cigarette smoke out of the air."

I have read that those are effective strategies. Even moving the feeders a few feet will sometimes work. However, I have solved the problem.

I noticed that the bees always clustered around one particular spot where the reservoir joined the base. They would pile up on top of each other there, leaving other parts of the feeder, including the little "flower" accesses, alone. With incredible powers of deduction, I surmised that maybe they piled up there because there was something there that they liked to eat. Another clue was that the bees pretty much ignored the red feeder, assembling only on the purple one.

I unscrewed the reservoir, daubed a generous helping of RTV Silicone onto the threads, reassembled it and let it dry.

No more bees.
