So I have Ultimate Hive covers on all of my hives (3). When I went out this morning to inspect, I found ants crawling out of two tiny holes in the underside of the cover! I thought they maybe were just visitors, but when I jarred the cover on the ground, they started spilling out in droves and some were carrying eggs. I put duct tape over the holes hoping to keep ants from getting in or out, but I don't know if that will hinder the ability of the cover to do its job.

Anyone have any advice?
