Honey Bee Swarms

Honey bee swarming is a natural reproductive behavior where a colony splits, with the old queen and thousands of worker bees leaving to establish a new colony.

What is a Honey Bee Swarm?

A honey bee swarm occurs when a single colony divides into two or more colonies.  The old queen departs with roughly half of the worker bees, leaving the remaining bees with a newly developing queen.  Swarming is a critical part of the honey bee life cycle, ensuring the survival and expansion of the species.  Swarms often cluster temporarily on tree limbs, shrubs, or other structures while scout bees search for a suitable new home.

Why Do Bees Swarm?

Swarming is triggered by several factors:

Overcrowding: When the hive becomes too full, bees instinctively split to relieve congestion
Reproduction: Swarming allows the colony to reproduce at the colony level, creating new colonies for species survival.
Resource Scarcity: Limited nectar or pollen may prompt bees to relocate to areas with more abundant food.
Hive Conditions: Enviromental factors such as temperatre changes, poor ventilation etc can trigger swarming.

Before swarming the colony prepares by constructing special queen cells for the next generation of queens and the old queen is fed less to slim down for flight.

 

Swarming bees are generally not aggressive, as their focus is on finding a new home rather than defending the hive.  The swarm may temporarily rest in a cluster for hours even a couple of day while scout bees evaluate potential nesting sites.  Once a suitable location is found, the swarm moves to establish the new colony.

Safety and Management

It is usually best to observe from a safe distance and avoid disturbing the swarm, as bees will sting if provoked.  Contact us and we will come along and have a look if we can safely remove the swarm and rehome it in one of our apiaries.  We may use a swarm trap and leave it overnight before collecting the following day.

Timing

Swarming typically occurs in late spring and early summer, during the warmer hours of the day, when colonies are at their peak population and resources are abundant.
