First year, first package ... I currently have a screened bottom w/ IPM board in place, deep body, top feeder, inner cover, cover.
In the feeder I put a 1:1 sugar solution. This morning I checked the feeder and the inner cover was covered in a variety of molds.
Now, the top feeder is this one:
The screen in the middle keeps the bees from just diving into the sugar and drowning. I had originally had the outer cover propped open for ventilation but of course the bees went in that way and drowned in the feeder (lots and lots of them). So, I removed that. The inner cover doesn't have a notch, so it isn't helping for ventilation ... actually I don't think I need it in there at all, but the mold problem would just move to the outer cover I am sure. I would guess I need more ventilation. So, what is the best approach?
I could remove the screen and put together some floats for the feeder instead ...then I could prop the outer cover.
I could place a screen over the inner cover hole and prop the outer cover, thus preventing access to the feeder from the outside.
6 of 1, half dozen of the other? Or something else I should be considering?
