Bill Truesdell asked, “Did you add the honey-be-healthy to the formic 50% solution?” And Mike in LA suggested, “Temperature difference?” I have always used H-B-H as per instructions and although there was a slightly higher temperature, 32°C instead of 24-28°C, I can’t see that making a lot of difference. It might make for a faster evaporation but the temperature around the queen is a pretty stable 36°C in summer.
