Storing Equipment During the Season

One of my favorite students called yesterday to say that she thought she had a swarm.  After some discussion, we decided her bees were robbing from some supers that are in storage.  In order to keep bees off of your equipment that is in "storage" you can put a lid or a piece of plywood on top of the boxes.  The idea is not to allow any insects inside the boxes from the top or bottom so if you have a queen excluder, you can place that underneath the stack of boxes and then cover the top.  Any holes in the boxes will attract robber bees and other insects so you can cover any holes with duct tape.
