After every major storm, I start getting the same phone call: A tree fell…and there are bees inside! It surprises a lot of people, but the storm didn’t cause the bees to move in. In most cases, the colony has been living inside that tree for months—or even years. The storm simply exposed a home that was already there.

This blog has a few tips on how you can prevent honeybees from moving into a tree in your yard!

Why Honey Bees Choose Dead Trees

Wild honey bees naturally like to nest inside protected, insultated cavities. One of their favorite places is the heart hollow of an old, dead, or dying tree. As trees age, the center of the trunk often begins to decay. Over time, this decay creates a hollow cavity that provides everything a honey bee colony needs:

• Protection from predators
• Insulation from extreme temperatures
• Shelter from rain and wind
• A secure space to raise brood and store honey
• Room to expand

To a swarm of honey bees searching for a new home, a hollow tree is prime real estate!

Unfortunately, these older trees are also the ones most likely to fall during severe weather. When they do, the colony suddenly becomes visible, and curious homeowners often discover thousands of bees living inside.

How to Reduce the Chances of Honey Bees Moving Onto Your Property

You can’t prevent every swarm from exploring your property, but you can make your home much less attractive by eliminating spaces that resemble a hollow tree.

1. Remove Dead or Dying Trees

Dead trees are much more likely to develop the heart hollows that attract honey bee swarms. Removing hazardous trees not only discourages nesting but also helps prevent costly storm damage.

2. Repair Hollow Structures Around Your Home

I’ve removed honey bee colonies from porch columns, walls, sheds, barrels, and other hollow structures. If a cavity is large enough for bees, they’ll investigate it as a potential home.

3. Seal Entry Points Before Bees Find Them

Inspect your home for gaps, cracks, and openings that lead into walls or other enclosed spaces. Permanent repairs using wood, flashing, hardware cloth, or expanding foam are generally much more effective than relying on caulk alone for larger openings.

4. Pay Extra Attention to the North and South Sides of Your Home

During my feral honey bee research in the southeastern United States, I found that wild colonies most often selected nest entrances on the north and south sides of structures. If you discover gaps or openings on those sides of your home, consider moving those repairs to the top of your to-do list.

5. Don’t Forget the Roofline

Some of the most common entry points for honey bees include:

• Loose fascia boards
• Soffits
• Roof vents
• Chimney gaps
• Openings around utility lines

These areas are easy to overlook until a swarm finds them first.

Your Home May Look Like a Hollow Tree

From a honey bee’s perspective, your home may simply provide cavities that resemble the heart hollow of an old tree.

If you eliminate the cavity, you’ve eliminated the invitation.

The Bottom Line

Storms don’t create honey bee colonies—they reveal them.

If you find bees living inside a fallen tree, chances are they’ve called that tree home for quite some time. Understanding why honey bees choose these natural nesting sites can help you better protect your property while appreciating the remarkable way wild colonies survive in nature.
