Winter Beekeeping in Charlotte, NC: What Your Hives Are Doing Right Now

Winter Beekeeping in Charlotte, NC: What Your Hives Are Doing Right Now

While winter here in Charlotte, NC started off warmer than average, December marked a noticeable shift. Temperatures have dropped, rain has been frequent, and forecasts suggest colder conditions are here to stay. While no one can say for sure whether we’ll see significant snow this winter, it’s very likely that this season will be colder than average for our area.

So what does this mean for honeybees, or for your hives if you keep bees or participate in our Hive Host program in Charlotte, NC?

Should You Inspect Beehives in Winter?

One thing is absolutely certain: now is not the time for deep hive inspections. Any major hive work should have been completed months ago. Honeybees do not hibernate, and winter is actually when colonies are using some of the most energy all year.

Do Honeybees Hibernate in Winter?

No, honeybees stay active throughout winter. While they are no longer foraging, building comb, or pollinating, they are doing some of the most important work of their lives.

Winter bees survive by converting stored honey into heat. Think of honey as fuel and the bees’ bodies as the furnace. By vibrating their wing muscles, bees generate heat that warms both themselves and the hive.

How Warm Is a Beehive in Winter?

Even if it’s 30 degrees outside in Charlotte, the bees inside your hive are maintaining a temperature close to 90 degrees. This is one of the great marvels of nature and the reason honeybees need so much honey to survive winter.

Most colonies require around 30 to 40 pounds of honey to make it through the season.

Why Bees Cluster in Winter

To maintain warmth, bees form what is known as a winter cluster. The center of the cluster is the warmest area and houses the most important members of the hive: the queen and the brood.

Breaking this cluster causes rapid heat loss, which is why winter inspections can be dangerous.

Why Opening Hives in Winter Can Be Harmful

Pulling frames or separating boxes during winter can disrupt the cluster and cause a sudden drop in temperature. When this happens, even normally gentle colonies may become aggressive.

Bees instinctively protect the brood, and even a brief temperature drop can chill and kill developing larvae.

Winter Hive Management for Charlotte Beekeepers

That doesn’t mean there is no winter hive management. It simply means that any work done should be minimal and done carefully.

For Hive Host clients in Charlotte, NC, you may see your beekeeper stopping by to add light insulation or emergency food to help the hive retain heat.

Treating Varroa Mites During Winter

Winter is an excellent time to treat for varroa mites. With brood levels very low, oxalic acid vapor treatments are especially effective.

Oxalic acid is an organic compound that significantly reduces mite populations and helps colonies enter spring healthier and stronger.

Monitoring Food Stores in Winter Beehives

Generating heat requires a tremendous amount of energy, and colonies can burn through honey quickly. Monitoring food reserves during winter is critical.

If stores run low, emergency feeding may be necessary.

Our preferred winter supplement for both our own hives and our Hive Host clients in Charlotte and surrounding areas is fondant, such as Hive Alive fondant patties. On warmer winter days, we may briefly open a hive to check food levels. This should never be done on cold days, as even cracking the lid can allow too much heat to escape.

Is It Normal to See Dead Bees in Winter?

Seeing dead bees near the hive entrance during winter is completely normal. Dozens of bees can die each day this time of year.

When temperatures allow, worker bees carry dead bees away from the hive. On colder days, they push them toward the entrance or onto the bottom board, which is sometimes as far as they can manage.

What Beekeepers Should Do During Winter

There is very little to do inside the hive during winter, but this is a great time to work around the apiary.

Winter is ideal for planning the upcoming season, purchasing equipment, painting boxes, building frames, and preparing hive stands. It’s also a good opportunity to reflect on the past season and decide what you want to improve next year.

And finally, rest. Spring arrives quickly in the South, and being prepared is one of the best things you can do for your bees.
