How honey bees beat the summer heat

Aug 10, 2023

When summer rolls around, soaring temperatures can make life uncomfortable for all creatures. While humans find relief in mechanical air conditioning, honey bees adopt a different, ingenious strategy. Without any mechanical devices, these insects have mastered the art of natural air conditioning to ensure the survival of their colony.

Honeycomb integrity is essential for bees. This structure, made of wax, houses honey, as well as the eggs and larvae that will grow into the next generation of bees. In the scorching heat, this wax can soften and even collapse. It is amazing how bees can keep their hives intact in hot weather, even though they are made of delicate materials and can weigh up to 100 pounds when full of honey.

So, how do these tiny engineers tackle this problem?

Firstly, bees might resort to "bearding." This isn't about facial hair but rather a phenomenon where hundreds or even thousands of bees hang outside the hive. It might look like they're just lazing about, but in reality, they're reducing the internal heat load. And contrary to what some might think, it's not a sign of the bees getting ready to swarm.

Upon closer observation, one can notice another tactic. Several bees line up near the hive entrance, heads outwards, rear inwards, rapidly fanning their wings. This action isn't random. By doing this, they induce airflow, cooling the interior much like a natural fan.

Water also plays a critical role in the bees' cooling strategy. Some bees, often termed 'water carriers', have the job of finding water sources. They fill their stomachs with water, return to the hive, and then distribute it within. As other bees' fan and create airflow, this water evaporates. Much like our sweat cools us down, this evaporation cools the hive.

Honey bees are not just hard workers, they're also smart engineers. The way they keep their hives cool in the hot summers is amazing. Next time you're feeling hot, think of the bees and how they cool down without any fancy technology.

Border View Farms is a mid-sized family farm that sits on the Ohio-Michigan border. My name is Nathan. I make and edit all of the videos posted here. I farm with my dad, Mark and uncle, Phil. We also have a part-time employee, Brock. My dad started the farm in 1980. Since then we have grown the operation from just a couple hundred acres to over 3,000. Watch my 500th video for a history of our farm I filmed with my dad.

I started making these videos in the fall of 2019 as a way to help show what I do on a daily basis as a farmer. Agriculture is different from any other industry and I believe the more people that are showing their small piece of agriculture, helps to build our story. We face unique challenges and stressful situations but have some of the most rewarding payoffs in the end. I get to spend everyday doing what I love, raising my kids on the farm, and trying to push our farm to be better every year. I hope that I can address questions or concerns that you might have about farms and agriculture.
