I've discovered three black ant nests in three hives this spring between inner covers and telescoping tops. I switched the solid inner covers to screened ones so the ants don't have any floor to set up shop on, and I sprinkled cinnamon in the covers as a further deterrent. The ants dispersed and all seemed well, but today I noticed a trail of ants going up one of the hives again. They aren't between the two covers anymore now, they are between the metal and the wood in the telescoping top. Anyone have any ideas about how to get rid of them now that they are hunkered down where I can't get to them? I'm sure they are sneaking some honey out of the supers, although I'm not sure how much of a real problem they are.
