Well, I've discovered bees can be very persistent.
I mentioned before about my bees discovering a bucket of wood + water, and made it their favorite watering hole. Well, when that source dried up, they found another. Look at this picture:
With the removal of the blue bucket, the bees discovered the condensate water in the air conditioner window unit just next to it! The back cover is off the AC unit, and we saw bees drinking water in the lower edge of the unit. I wasn't happy to see that, since I want the bees to find water not on my neighbor's back porch. The neighbor got a kick out of the bees persistence - she said watching them it was like grand central station, with bees zipping back and forth between her AC unit and my hives (that's how she knew they were mine).
So I built a simple frame and stapled some window screening over it (I re-screened a screen door today and happened to have the left overs). Then tonight after the bees were in bed, I used some small bungee cords and attached the screen to the back of the AC unit, to keep the bees out.
I decided to put out again my bucket of water near the hives, with hopes that the bees will start to use that instead of water at my neighbors. I put some sticks in it that were in the original blue bucket. We'll see if they take to getting water from there.
I'm definitely going to have to give them a jar of honey, once I get some!!
