How hot is too hot for a honey bee?
That question doesn’t mean much sitting here in Calgary on a mild (20°C) summer day. It becomes important to my niece, keeping bees in southern Arizona where the thermometer was pushing 108°F.
I talked to my niece, beekeeper, teacher and frequent podcast guest, Monica King. She lives southwest of Tucson, where summer beekeeping operates… a little differently than it does in Canada.
For example.
Monica says her bees start working before sunrise. She goes outside around five in the morning and finds bees collecting water and visiting flowering mesquite. I had always associated honey-bee navigation with sunlight and polarization. The bees apparently hadn’t read the same books I had.
Water, for bees in Arizona, becomes more than something nice to have.
Monica described providing water directly inside weaker colonies with frame feeders when heat and low humidity make normal water gathering difficult. She also uses screened openings higher in the hive to improve airflow without simply opening the colony to robbing. Robbing screens, reflective hive surfaces, white boxes and empty rims above the inner cover all become part of managing heat.

After a disappointing spring, rain had finally arrived. Mesquite was blooming, asters were appearing, and Monica’s colonies were beginning to expand and store fresh nectar. For her, however, honey isn’t the main crop. She produces nucs for southern Arizona hobby beekeepers. With good monsoon rains, even a colony started in late summer may have time to build up for winter and get an early start the following spring.
Controlling heat and stress in hot hives:
Rotating ventilation discs
Lid offsets
Screened bottom boards
Empty rims above
White or light hive colours
Himalayan salt from spray cans
Apiary equalization
Robbing screens
Frame feeders filled with water
Monica and I also discussed dealing with bees in neighbouring swimming pools. She had a few tricks for those times when bees ignore the water you’ve set out for them and instead head down the street. That includes an algae killer I had never heard of before. Apparently, you can use it around the pool early in the morning to discourage water-collecting honey bees. That, and hosing the hives to give them water may distract them.
And, later in the podcast, we reached Africanized bees. I don’t think a “Beekeeping in Arizona” podcast would be complete without a mention of Killer Bees AHB.
Monica works around them routinely. Some colonies serve as vigorous donor colonies supplying brood and resources, while the nucs she sells to beginning beekeepers receive European-stock queens. She also does bee removals, always at night when temperatures are lower, bees won’t attack bystanders, and the bees are home.
That led us into a recent Arizona headline about a man reportedly attacked by “100,000 killer bees.” We were skeptical of the number, although certainly not of how frightening the experience must have been for the guy handling the weed whacker. From there, our discussion wandered into sensational bee reporting, Africanized-bee history, feral colonies, native bees and the question of whether honey bees and native pollinators must always be portrayed as enemies against each other.
Monica thinks natives and imports can get along. She teaches native-bee material as well as honey-bee management, and our conversation eventually settled on habitat. More flowers, greater plant diversity and fewer harmful chemical exposures can benefit many kinds of bees.
We even found time for Bayer/Monsanto, genetically modified corn, and a highly secured research greenhouse. A lab where they check your shoes when you leave.
So, yes, our conversation wandered.
But that’s the point when anyone makes the mistake of talking to me.
If you’d like to know more about this, and Arizona beekeeping, my About Bees, Culture, and Curiosity podcast goes into illuminating detail, so I invite you to listen and enjoy. The ideas expressed here on this blog and on the podcast are subject to refinement with my exposure to new facts.
