DIY Bee Swarm Traps: How to Build and Use Them Effectively

Bee swarming is a natural process in which a colony splits and a group of bees leaves to establish a new home. Capturing a swarm can be an effective way to start or expand an apiary. DIY bee swarm traps provide an inexpensive and eco-friendly way to attract and capture swarms safely. This guide will walk you through how to build and use swarm traps effectively.

Why Use a Bee Swarm Trap?

Swarm traps offer multiple benefits, including:

  • Providing a safe and controlled way to collect honeybee swarms.
  • Preventing swarms from settling in undesirable locations, such as inside walls or attics.
  • Supporting local bee populations by offering a suitable nesting site.

Materials Needed for a DIY Swarm Trap

To build an effective bee swarm trap, you will need:

  • A wooden box or repurposed deep hive body – A container with a volume of approximately 40 liters is ideal.
  • Frames with old comb or foundation – These help attract scout bees.
  • Swarm lure or attractant – Essential oils such as lemongrass oil mimic queen pheromones and draw in bees.
  • Ventilation holes and an entrance – A single entrance hole (about 1 inch in diameter) ensures easy access for bees.
  • Secure lid and hanging hardware – Ensuring the trap is weatherproof and easy to mount.

Building Your Swarm Trap

1. Construct the Box– Use plywood or a wooden hive body with a volume of 40 liters.


2. Create an Entrance– Drill a small hole (about 1 inch) as an entry point for bees.


3. Install Frames – Place old comb or foundation frames inside to encourage bees to settle.


4. Add a Swarm Lure– Apply a few drops of lemongrass oil inside the trap to attract scout bees.


5. Secure the Lid – Ensure the lid is tightly sealed to protect the swarm from rain and predators.


6. Install Hanging Hardware – Attach a strap or bracket for mounting the trap.

Placing the Swarm Trap

For the best results, consider these factors when positioning your swarm trap:

  • Height – Place the trap at least 8-12 feet off the ground.
  • Location – Choose an area near existing bee activity, such as near tree lines or apiaries.
  • Sunlight – Partial shade is preferred to prevent overheating.
  • Accessibility – Ensure the trap is easy to reach for regular inspections.

Monitoring and Capturing the Swarm

Once your trap is in place, follow these steps:

1. Check Regularly– Inspect for bee activity every few days.

2. Look for Scout Bees– If bees are frequently visiting, a swarm may soon move in.

3. Confirm a Successful Capture – When a large number of bees are present, the swarm has likely settled.

4. Transfer to a Hive – Once captured, carefully relocate the swarm to a permanent hive within a few days.

Tips for Success

  • Use multiple traps to increase the chances of capturing a swarm.
  • Replace old lures and refresh lemongrass oil periodically.
  • Avoid disturbing the trap once bees start showing interest.
  • Ensure the trap is secure to prevent damage from wind or predators.

Conclusion

DIY bee swarm traps are an excellent tool for beekeepers looking to expand their apiaries while aiding in pollinator conservation. With the right materials, proper placement, and regular monitoring, you can successfully attract and capture bee swarms. By following this guide, you can create an effective and humane solution for swarm collection and hive expansion.

ABOUT US

We are a family-run Honeybee farm and rescue. Our journey started in 2019 just before the start of the pandemic, one of the most uncertain and isolated times worldwide. We have had many successes and many failures along the way with our beloved Honeybees and want to be able to educate others about something we care so deeply about as we continue to learn ourselves along the way. We live in zone 7b and will be making videos on how we do things, not necessarily how you should run your operation in different areas of the country. We are learning every day and will continue until the day they put us on the ground. No one said it better than Bob Binnie, "Beekeeping is 50% science and 50% art." We hope you'll enjoy following along on our journey, whether you are a beekeeper or not! Lolly & Poppy
