In extreme temperatures, your bee colonies could literally melt. Read on for tips to safely help your bees survive the dangers of heatwaves. Water is critical for cooling the hive. Worker bees collect it in their honey guts and carry it back to the hive where it is used for evaporative cooling.
Do bees stay in the hive in the summer?
During the summer, regardless of the outside temperatures, bees try to keep their hives at the same 95-degree F temperature. The forager bees are out of the hive looking for pollen, nectar, and water during the day which helps keep the temperature down. Some of the bees that stay in the hive will be put on wing beating duty.
Where do bees go when it’s Hot?
Hot weather can be tough on our local wildlife, including wild bees. Honeybees, for example, need a steady supply of water to make honey and feed members of their hive, and on hot days, water sources are especially critical. But where to go? Rivers, creeks, swimming pools, and even bird baths can be risky for bees trying to quench their thirst.
Do bees need water when it's Hot?
When there is heat, the importance of water to bees cannot be emphasized enough. Provision of ample water and good ventilation for a hive is quite important. On a particularly hot day, bees use an impressive amount of water per day.

Are bees affected by hot weather?
Although bees are tolerant of temperatures well into the mid-nineties, they really do not like it much hotter. For resources or conditions such as light availability, water availability, and temperature all species have an optimal zone or range.
What happens if bees get too hot?
If the hive gets too hot the brood can die, so the bees move outside instead of working to lower the hive temperature. When bees get too hot, all production stops and the queen stops laying eggs.
How do bees survive heat?
Workers pack together on the outer edge to create an insulative outer shell to hold heat in the center of the nest. The bees distribute droplets of water around the nest, which works in parallel with the fanning to create the equivalent of honey bee AC. Honey bees are somewhat adapted to extreme heat.
What temperature do bees not like?
Bees tend to come out when it's warm enough to gather their nectar and return to the hive when it becomes too cold. This is because bees start to feel drowsy and fall asleep if the temperature outside goes below 50 to 55 degrees Fahrenheit.
What temp kills bees?
Honeybees have a strong temperature tolerance and have adapted to live in many parts of the world where there are extreme temperatures. Despite their high degree of tolerance, a bee will die if it becomes too hot (above 45°C or 113°F) or too cold (below -2°C or 28°F).

Provision of appropriate ventilation by making use of either a screened bottom board, a slatted rack or slatted bottom board: Though provision of adequate water would keep the temperature low, but it would be quite difficult to keep the nectar dry so the bees have to fan more using their wings. Instead of making them use a lot of energy in fanning, you can just provide appropriate ventilation.
Why is ventilation important for honey?
Good ventilation helps with honey hydration. Your bees would love to dehydrate all the honey they bring in, and if it is warm, the air would not escape easily, this would take more bees fanning to get it dry, and if it is not dry there would be less room to store more nectar.
What does it mean when a bee hive is hanging out?

Some of the bees that stay in the hive will be put on wing beating duty. They’ll beat their wings to circulate air through the hive and reduce the temperature.
Why do bees need ventilation?
During the summer, the bees need ventilation. As they bring in water, the humidity in the hive rises and it’s harder for the nectar to dry, so they have to fan more. They use an incredible amount of energy fanning air that goes nowhere. Therefore, it’s best to give them some ventilation to move the air more efficiently.
