Re: Help! Massive Heat Wave. Is there anything can I do to help my bees?
If you want to let the bees use physical effects they "know" how to use,
1.) shield them from the sun so they don't have to get rid of the added heat. I use aluminum foil for some such purposes. In NoCal, you might think about taping some to the southernmost side of the hives. I used to have aluminum Venetian blinds with polished aluminum finish on one side and alabaster white on the other. The western-facing kitchen was lots cooler in the summer evening sun with the blinds closed with the reflective side out.
2.) It's arid where you are. Folks use "swamp coolers" and I have read that the bees use evaporative cooling that same way. They should probably be the ones controlling their airflow so that as air passes through, it evaporates water and things cool off. With unlimited airflow at low hum, the inside of the hive will cool off, but only until the water evaporates. Think "swimsuit in a hot breeze," and remember the breeze only feels cool until the water dries up and takes the larvae with it.
3.) listen to people with experience more than you listen to me. Ray above is probably a good candidate. But it ought to make sense eventually, and you ought to be able to do things that make the bees' jobs (staying alive; making more bees) easier.
