Re: ccommercial way for installing packages
We used to do 1,000+ yearly "back in the day". If the temps were warm we gave the bees a light spray of sugar water and then plugged the queen cage entrance with a small bit of granulated honey to keep her from running out and potentially flying and wedged the cage between two frames. When temps were cooler we just dumped the bees on the bottom board gently placed the frames in and then layed the opened queen cage between two of the frames. Yeah it could be a pain getting them back out later but it seemed to be the most reliable way of safely releasing her into the cluster. The biggest threat was always drifting when the weather was warm. Cool temps almost always guaranteed success. Queen losses were rare. If I were only doing a few I would definitely install them at night if the forecast was warm.
