We just purchased 50 new mini mating nucs from Mann Lake. They are the IN-140's, seen online at http://www.mannlakeltd.com/beekeepin...es/page60.html. They are constructed from high-density styrofoam, and I am wondering how long and how well they hold to the sun and other elements. I have seen them painted, and I'm wondering if it is worth taking the time to give them a quick coat of paint. Also, would painting them different colors help with drifting? Thanks in advance for your help.
