We all know that beekeeping is both an enjoyable and rewarding activity, but it does come with challenges. One of these challenges is ensuring that the bees are comfortable in their hive, especially during hot weather. Bees regulate their temperature by fanning their wings and gathering water, but sometimes the heat can become too much for them to handle. High temperatures can cause a decrease in honey production, a decrease in the lifespan of worker bees, and it could even cause the entire colony to abandon the hive. As a beekeeper, it is important that you understand how to detect when your bees are too hot and then how to help them cool down to keep them healthy and productive. In this article, I will offer up some tips and information on how to know if your bees are too hot and what measures you can take to prevent heat stress.
The Correct Temperature for Bees
Maintaining the correct temperature in a beehive is crucial for the survival and productivity of the colony. Bees are very sensitive to changes in temperature, and any significant fluctuations can have a detrimental effect on their health and productivity. Your job as a beekeeper is to ensure that your hive stays within the optimal temperature range.
Bees have a unique way of regulating the temperature within their hive. They maintain a core temperature of around 95F by fanning their wings and evaporating water. This process helps to cool the hive down when the temperature rises above the optimal range. However, if the hive is placed in direct midday sun during the warmer summer months, the temperature inside can rise quickly. In this situation, the bees may struggle to cool it down.
When the hive temperature rises above 95F, the bees become stressed and their productivity decreases. They spend more time fanning their wings to cool the hive down, which can result in them becoming fatigued and unable to perform their other duties. If the hive temperature continues to rise then the brood will start to die, which will have a significant impact on the colony’s overall health.
By the way, a similar thing happens if the temperature in the hive drops too low. The bees will struggle to maintain the correct temperature and they may have to cluster together to conserve heat. This can lead to a decrease in their activity level. The brood may also be affected, and their development may slow down.
To maintain the correct temperature in the hive, it is essential that you choose the right location for it. The hive should be placed in a shaded area away from direct sunlight during the warmer months. You can also provide additional ventilation to help regulate the temperature inside. This can be achieved by adding ventilation holes or using a screened bottom board.
Is the Hive Too Hot?
As mentioned above, if the hive becomes too hot, it can cause the bees to become stressed. This can then lead to a decrease in honey production, a reduced number of eggs laid by the queen, and, in severe cases, the death of the entire colony.
Ideal Hive Temperature
The ideal temperature inside a hive should be around 93°F (34°C) during the day and drop to around 57°F (14°C) at night. It’s important to note that these temperatures can vary depending on the time of year, hive location, and other factors.
Signs that the Hive is Too Hot
One of the most apparent signs that your hive is too hot is when you see bees clustering outside the hive in large groups. This behavior is called bearding; it’s the bees’ way of regulating the temperature inside the hive. Bees beard when they need to cool down and they do this by fanning their wings and creating airflow to circulate fresh air throughout the hive. However, if you notice that the bearding is excessive then it could indicate that the hive is too hot and the bees are struggling to regulate the temperature inside.
Another sign of a hot hive is reduced honey production and egg-laying. Bees are hardworking creatures, but when the temperature is too hot they tend to slow down and become less productive. If you see that your honey production has decreased or the queen is not laying as many eggs as usual, it could indicate that the hive is too hot.
What to do if Your Hive Gets Too Hot
It is always best to prevent your hive from becoming too hot if you can. I have already mentioned that you should look for an area that is both protected from the midday sun and that has some level of shelter from wind and rain. Having said that, you will have to make sure that the flight path of your bees is not blocked. An area that has afternoon shade is the best location as this will prevent the hive from overheating.
If you are worried that the sun is going to be a problem, you could always paint your hive white as this helps reflect sunlight and help keep it a little cooler. However, if you do this you will need to fully air the hive and allow it to dry completely before introducing your bees. Bees do not like the smell of chemicals; if they detect a strong odor, they may abscond.
To make sure the hive is getting enough ventilation during the summer, consider buying screened bottom boards. This allows more air to enter and reduce the work required on the part of the bees in keeping the hive sufficiently ventilated.
Some beekeepers will raise the roof of the hive slightly with shims, while others will go for screened inner covers. How you choose to ventilate the hive is up to you. Do note though that if you have chosen to raise the roof with shims, it is important to remove them during late summer when foraging options decrease as this is when robbing of the hive is more likely.
Another way to keep the hive cooler is to remove a frame. This means using one less frame than your hive has the capacity for as this will ensure that the hive does not become too crowded.
What Temperature is Too Hot for Bees – Conclusion
In conclusion, maintaining the correct temperature inside a beehive is essential for the survival and productivity of the colony. Bees are sensitive creatures, and even small fluctuations in temperature can have a significant impact on their health and productivity. As a beekeeper, it is crucial to understand the signs that your hive is too hot and take measures to prevent heat stress. You can help your bees stay cool by choosing the right location for your hive, providing additional ventilation, and removing excess frames. By ensuring that your bees are comfortable in their hive, you can help them stay healthy and productive, which is essential for the success of your beekeeping operation.

Beekeeping, like any agricultural activity, involves inherent risks. It is important to understand these risks and take appropriate measures to mitigate them.
Potential risks associated with beekeeping include:
- Bee stings: Honey bees are generally not aggressive but can become defensive if they feel threatened or their hive is disturbed. Bee stings can cause allergic reactions or even anaphylaxis in some individuals, which can be life-threatening. It is important to wear protective clothing and follow best practices when handling bees to minimize the risk of stings.
- Diseases and pests: Bees can be vulnerable to various diseases and pests, including mites, viruses, and bacterial infections. These can have significant impacts on bee colonies, leading to reduced honey production or even colony collapse. It is important to monitor hives regularly and take appropriate measures to prevent and treat diseases and pests.
- Weather conditions: Extreme weather conditions, such as drought or cold temperatures, can affect the health and productivity of bee colonies. It is important to ensure that hives are appropriately sheltered and provided with adequate food and water.
- Environmental hazards: Bees can be affected by environmental hazards such as pesticide exposure, pollution, and habitat loss. It is important to be aware of these hazards and take appropriate measures to protect bee colonies and promote healthy environments for bees.
- Legal requirements: Beekeeping may be subject to local, state, or national regulations, such as registration or inspection requirements. It is important to be aware of these requirements and comply with them.
While beekeeping can be a rewarding and enjoyable activity, it is important to be aware of the potential risks and take appropriate measures to mitigate them. By following best practices and staying informed about the latest developments in beekeeping, beekeepers can help ensure the health and productivity of their hives and contribute to the well-being of bee populations worldwide.
