What to Do When a Swarm of Bees Appears on Your Property
Discovering a large group of bees gathered on a tree branch, fence, or side of a house can be alarming. However, a bee swarm doesn't always mean immediate danger or an established bee colony.
Honeybee swarming is a natural process that occurs when part of an existing colony leaves to establish a new home. During this process, thousands of bees travel with a queen before temporarily landing in one location.
A swarm often forms a temporary cluster on tree limbs, shrubs, fences, pole lights, or other exposed surfaces. These bees wait while scout bees search for a suitable nesting location. Because these bees are not protecting an established nest with brood (nursery) and stored food, swarming honeybees are rarely aggressive.
Temporary swarms often move on within several hours or a few days once they find a suitable new home. Some swarms may remain longer. Weather conditions, available nesting locations, and the colony's behavior can influence how long the cluster stays. This is unpredictable.
The safest response to a bee swarm is to keep a respectful distance and to avoid disturbing the cluster.
DO NOT hose down, knock down, or spray the cluster!
When bees repeatedly enter and exit an opening in a wall, roofline, chimney, or other enclosed space, this consistent activity usually
indicates that honeybees have begun building wax honeycomb and are using the structure as a permanent home.
Recognizing the difference matters because bee removal methods depend on where the insects are located.
A temporary swarm is resting outdoors and usually leaves naturally without intervention.
An established colony is inside a structure and generally requires professional bee removal to address the insects, honeycomb, and potential structural concerns.
Leaving a bee swarm alone may be appropriate when it is located away from regular activity. However, a cluster near a doorway, playground, or frequently used outdoor space may present a safety concern.
Please note: Nearly all people have reactions like redness and/or swelling due to bee venom. However, only a very small percentage of individuals actually are allergic to bee stings. Of course, those with known bee sting allergies should take additional precautions to avoid exposure.
A bee removal professional can assess whether the insects are honeybees, identify signs of an established colony, and determine the appropriate response. Depending on the circumstances and health
of the bees, professional bee removal may involve collecting and relocating the bees rather than eliminating them.
For colonies inside structures, proper removal requires removing all honeycomb and sealing entry points after eliminating the colony. Leaving honeycomb behind can attract pests or create additional maintenance problems.
