I installed two packages back in March when the weather was cold and windy. Since the top bars weren't sealed with propolis, I put down newspapers over the bars to help keep drafts out until the bees could seal things up. March and April were cold and windy so the newspapers stayed there five or six weeks. When I took the paper up there was an ant colony in the top of one hive between the pages of the newspaper complete with eggs and everything. They had the perfect world. The heat from the bees were keeping them warm and all they had to do was slip between the top bars for food. They were quickly evicted. Which brings me to my question. I've read that ants don't like coffee so I was thinking about saturating the ground around the hives with coffee grounds (I can get a ton of them from work). I was wondering if anyone had ever tried this?
