This month in the hive, we’re keeping our bees cool. On humid days, you might notice bees resting outside of the hive, which is their way of cooling off. Most of the time, bees can fan hot air out of their hives. But when the outdoor temperature reaches the upper 90s and into the 100 degrees, the heat might be too much for them. Luckily, there are methods you can take to protect your bees during extreme heat.
A water source is best for cooling down your bees when it’s hot outside. Bees tend to favor water from ponds, creaks, and streams. You can set up a small bee pond easily with buckets or barrels, which you can fill with water and floating plants like water lettuce or water hyacinth. You could also invest in a trickling fountain, as long as the current isn’t too strong. Bird baths are also perfect for bees, though introducing a second bath may be a good idea as bees can sometimes deter birds from using the same bath. In your bee bath, add rocks to the water to provide an additional landing area for the bees.
Another simple method for cooling off your hives is providing them plenty of shade. Set up an umbrella or tarp over your hives, or keep them in shaded areas, such as underneath trees. Metal hive roofs, though durable and stylish, might also be exacerbating the heat in your hives. Try covering your metal with something light colored, like white sheets or plywood.
Those are just a few ways to help your bees beat the heat this summer. While they may prefer the warmer weather all year round, sometimes it can get too intense for the hives, and they may shut down brood production or even lose colonies. Keep a careful eye on the rising temperatures and your hives moving forward!
