I work with a non-computing beekeeper that mentioned that I could do some research for him. He asked my thoughts on him moving his bees for the winter about 2 hours south of where we are at for the warmer air but more so for placement on white sand. His thoughts were that he had been down there on cool spring days and these locations were warmer than others that were not on sand in the same Geography. My thinking is that white reflects the light spectrum and does not absorb heat, he would be better putting them on something dark colored. On the other hand, maybe the sand reflects more light onto the hive? Any colorful thoughts? Having started our discussion on colors, he wondered aloud if the black plastic or landscape cloth placed underneath hives would diminish hive beetle populations. I did not say anything but recall that the beetles travel quite a distance if needed, but I do not know. It also seems that the plastic or cloth would be susceptible to injury. Any feedback on this?
