I bought one of the bee escape boards that uses a triangle shaped wire cover over the hole in the center. Dadant sells it. It worked the first time I used it on a honey super, but the last time I found quite a few residents not wanting to go. I'm trying it again today, but I was curious if anyone has had a similar problem. I did get some of the plastic ones that fit into the innercover slot, but I wanted to give "The Triangle" one more try.
