Hello, Is it correct and safe to overwinter colonies with the same apistan strips that I pulled before the honey flow? I am now installing them in colonies after I pull the honey. We have about 500 hives so I am concerned. I am concerned about mite resistance to the strips, thus cutting my own throat. Also, is there any interaction with the powdered sugar terramyacin mix and the apistan. We treat with terra mix outside of the honey production season also. Any help is greatly appreciated.
