Swarm Management Techniques: Keeping Your Bees Under Control

Swarming is a natural reproductive process for bees, but it can be problematic for beekeepers. When a colony swarms, the old queen and about half the worker bees leave the hive to establish a new colony. This can reduce the productivity of your original hive and create challenges if the swarm settles in an undesirable location. Effective swarm management techniques are essential to maintain strong, productive colonies and prevent the loss of bees. This guide covers various strategies to manage and prevent swarming.

Understanding Swarming

Why Do Bees Swarm?

Swarming occurs for several reasons:

• Overcrowding: When the hive becomes too crowded, bees feel the need to split the colony.
• Old Queen: An aging queen produces fewer pheromones, which can trigger swarming.
• Genetic Predisposition: Some bee strains are more prone to swarming than others.
• Environmental Factors: Weather conditions, availability of forage, and hive location can influence swarming behavior.

Signs of Swarming

Beekeepers can identify potential swarming by observing:

• Queen Cells: Presence of multiple queen cells indicates preparation for swarming.
• Reduced Foraging: Bees become less active in foraging as they prepare to swarm.
• Beard-Like Clusters: Bees may cluster at the hive entrance in large numbers.

Preventing Swarming

Providing Adequate Space

Ensure your bees have enough space by adding supers or brood boxes as the colony grows. This reduces the likelihood of overcrowding and gives the bees room to expand.

Regular Inspections

Conduct regular hive inspections, especially during the swarming season (spring and early summer). Look for signs of swarming, such as queen cells, and take action if needed.

Hive Splitting

Splitting the hive is an effective method to prevent swarming. By creating a new colony, you reduce the population density in the original hive. Here’s how to do it:

1. Identify Frames: Select frames with brood, bees, and resources.
2. Create a New Hive: Place the selected frames in a new hive box.
3. Introduce a Queen: Introduce a new queen or allow the bees to raise one from the brood.

Removing Queen Cells

During inspections, remove any queen cells you find to discourage swarming. However, this is a temporary solution and must be done regularly.

Requeening

Requeening your hive with a young, productive queen can reduce the tendency to swarm. Younger queens produce more pheromones, which helps maintain colony cohesion.

Providing Ventilation

Improve hive ventilation to prevent overheating, which can trigger swarming. Use screened bottom boards, upper entrances, and proper hive placement to ensure good airflow.

Supercedure Management

Supercedure is when bees replace an old or failing queen. Manage this process by regularly requeening to avoid unexpected swarming.

Controlling Swarms

Catching Swarms

If your bees do swarm, you can attempt to catch and hive them. Here’s how:

1. Prepare Equipment: Have a spare hive or nuc box ready.
2. Locate the Swarm: Find where the swarm has settled, usually in a nearby tree or bush.
3. Capture the Swarm: Gently shake the bees into the box or use a bee vacuum.
4. Transfer to a Hive: Place the captured swarm into a prepared hive.

Bait Hives

Bait hives attract swarms and provide them with a ready-made home. Place bait hives in strategic locations around your apiary. Use pheromone lures or old brood comb to make the bait hive more attractive.

Post-Swarm Management

Inspecting the Original Hive

After a swarm, inspect the original hive to assess its condition. Check for:

• Remaining Queen Cells: Ensure that there are queen cells or a new queen to take over.
• Population Levels: Evaluate the remaining bee population and their ability to rebuild.

Supporting the Swarm Hive

Provide the new swarm hive with the necessary resources to establish itself. Feed the new colony with sugar syrup and monitor its progress.

Monitoring and Adjusting

Continue to monitor both the original and swarm hives. Make adjustments as needed to ensure both colonies thrive.

Seasonal Considerations

Spring Management

Spring is the most active swarming season. Increase the frequency of inspections and be proactive in providing space and resources.

Summer and Fall

As the season progresses, the likelihood of swarming decreases. Focus on ensuring the bees have enough resources to prepare for winter.

Winter Preparation

During winter, swarming is not a concern, but it’s essential to prepare for the next swarming season. Ensure your hives are healthy and well-provisioned to reduce stress and prevent swarming in the spring.

Advanced Techniques

Demaree Method

The Demaree method involves separating the queen from the brood to prevent swarming. Here’s how:

1. Separate the Queen: Move the queen to a new brood box with some brood and resources.
2. Add a Queen Excluder: Place a queen excluder between the old and new brood boxes.
3. Manage Brood: Regularly check and manage the brood to prevent the development of queen cells.

Checkerboarding

Checkerboarding involves alternating empty frames with frames of brood and resources. This technique creates the illusion of more space and delays the swarming impulse.

Snelgrove Board

A Snelgrove board is a double-screen board used to divide a hive vertically. It allows the bees to communicate through the screen while managing two separate brood chambers. This method can help control swarming and manage colony expansion.
