Re: Quick Deep Divider to Make 2 Nucs
Bees will eventually gnaw through styrofoam. Also, styrofoam has to be fairly thick to have the mechanical strength needed. The hack I've used is to cut notches using a skillsaw into the inside of the deep to accept a piece of 3/16 plywood. I put a thick rim on top and bottom of the plywood to maintain physical strength where it butts to the bottom board and top cover.
Be sure to use two small top covers so you can open up one side or the other separately. This is critically important to avoid losing queens. The top cover can be anything from a plastic bag to a small inner cover, you decide what works best.
