lotsobees: I've tried cinnamon in the past without much luck. But at the time, the ants were after the sugar water. Maybe these ants will be more deterred by the cinnamon. It's worth a shot, thanks for the reminder!
jgaito: I tried to track the ants back to their colony, but they are coming from the woods so no luck. Would have been nice to eliminate them from the source, though!
I've read about hives on legs that were placed in buckets of water. I'm going to play with that idea a bit for future problems. These two hives are on bricks, so am thinking more along the idea of painting the bricks with something. What, though, I haven't figured out yet, especially since I don't want the bees on it.
