Moving your bee colonies during the winter can be a daunting task, especially for inexperienced beekeepers. As temperatures drop and daylight hours shorten, bees become more defensive and vulnerable to disease transmission. If not done properly, moving bees in winter can lead to colony collapse, putting the health of both humans and bees at risk.
In this article, we’ll delve into the importance of understanding bee behavior, performing thorough health checks, and using the right equipment when relocating colonies during the winter months. We’ll also explore the risks associated with disease transmission and colony collapse, and provide tips on how to mitigate them. Whether you’re a seasoned beekeeper or just starting out, knowing how to safely move bees in winter is crucial for maintaining healthy colonies and ensuring a successful harvest come springtime.

Understanding Bee Behavior in Winter
When winter arrives, bees enter a state of dormancy called torpor, which affects their behavior and makes them less responsive to movement. Let’s explore how this impacts bee relocation during the cold season.
Why Bees Cluster in Cold Weather
When winter rolls around, you might notice that your bees have started clustering together inside their hive. This behavior is crucial to their survival and a testament to the colony’s adaptability. In cold weather, bees cluster because they need to conserve heat. A single bee can generate just 1/4 of a degree Fahrenheit (0.14 degrees Celsius) of warmth by flapping its wings – not nearly enough to keep the hive warm.
To compensate for this, thousands of bees will gather together to create a tight cluster around their queen. By doing so, they’re able to maintain a stable temperature, usually between 45°F (7°C) and 50°F (10°C), inside the hive. This collective effort is often referred to as “shivering” or “cluster heat.” It’s an incredible display of cooperation and social behavior that ultimately helps the colony endure harsh winter conditions.
As you consider moving your bees in winter, it’s essential to understand this critical aspect of their behavior. Attempting to disrupt a cluster can be detrimental to the colony’s chances of survival. If you must move them, make sure to do so carefully, keeping the colony intact and minimizing any disturbance to the cluster.
Effects of Cold Temperatures on Bee Colonies
When temperatures drop, bee colonies are severely impacted. Reduced activity is one of the most noticeable effects, as bees struggle to navigate and forage during cold weather. This can lead to a decrease in honey production, as bees produce less nectar-rich honeydew due to reduced foraging capabilities.
Cold temperatures also take a toll on colony mortality rates. As temperatures drop below 50°F (10°C), bee colonies start to experience increased losses. When temperatures plummet below freezing, the effects become catastrophic – entire colonies can perish within hours if they’re not protected. For instance, in 2014-15, an unusually cold winter in the northeastern United States led to significant colony losses, with some estimates suggesting up to 30% of beekeepers’ populations were wiped out.
To mitigate these risks, beekeepers must take proactive measures, such as providing supplemental feeding and protecting colonies from harsh winds and freezing temperatures. By understanding the effects of cold temperatures on bee colonies, you can better prepare your bees for winter and make informed decisions about their care.
Preparing for Winter Bee Movement
Before you attempt to move your bees in winter, it’s crucial to prepare them properly by taking specific steps to ensure their health and safety. This includes monitoring their nutrition and overall well-being.
Assessing Bee Colony Health Before Moving
Before moving your bees to a new location during winter, it’s essential to evaluate their colony health. This step is crucial as it ensures that you’re not introducing diseased or weak colonies into the new environment. A healthy bee colony will be better equipped to adapt to its new surroundings and improve its chances of survival.
To assess colony health, check for signs of disease, such as discoloration on brood, excessive moths in the hive, or a strong odor. Monitor the colony’s overall population and brood production, ensuring there are enough bees to occupy the new location. Evaluate the quality of the comb and frames, looking for any damage or deterioration.
Regular inspections will also help you identify potential issues before they become major problems. For instance, if you notice a significant decrease in honey stores or an increased number of dead bees, it may be a sign that the colony is struggling to adapt to its current environment, let alone a new one.
Choosing the Right Time for Winter Movement
When it comes to winter bee movement, timing is everything. You’ll want to consider several key factors before deciding on a move date.
Weather conditions play a significant role in determining the ideal time for moving bees in winter. Aim for days with light winds and minimal precipitation to avoid stressing your colony further. If possible, plan your move during periods of calm weather, typically between 9 am and 3 pm when temperatures are relatively stable.
Daylight hours also impact the decision-making process. Ideally, you’ll want to move your bees when there’s still sufficient daylight to inspect and set up their new location without feeling rushed. In areas with shorter winter days, it may be best to wait until the sun is out for a few more weeks.
Temperature-wise, temperatures above 40°F (4°C) are generally considered safe for moving bees in winter. This allows you to avoid exposing your colony to potential cold stress and associated health risks. Keep an eye on forecasts, and plan your move accordingly to ensure both you and your bees stay comfortable and healthy throughout the process.
