During & After a Honeybee Swarm (2024)

Though it’s a rare and truly beautiful sight, most beekeepers would prefer not to see half of their strongest colony and their successful queen leave their bee yard if that colony has decided to swarm.

Ahoneybee swarm is indeed a sign that your bees are healthy and expanding rapidly,too rapidly for the space they currently inhabit. If you can catch it in time, you may be able to prevent the swarm from happening, as wetouched on in another PerfectBee Snippet, “Why Honeybees Swarm”

But what if it’s too late? What are your options once a honeybee colony starts the swarming process?

What to Do if Your Colony Swarms

If you see signs that a swarm is imminent, like queen cells being built on the bottom of a frame, it may be too late to prevent the swarm from happening.

If that’s the case, your options are limited, but there are a couple available to you if you move fast, and all hope is not necessarily lost.

Catching a Swarm

If your colony has swarmed and left their beehive, but they are still close by searching for a new home, you may be able to capture the swarm and hive it into a new beehive.

To capture a swarm, it helps to have a few things on hand:

A box that bees can use as their new (temporary) home – Either a nuc box or single hive body with a top cover and bottom board can be used. Ensure they are filled with frames, preferably those that have some drawn combto entice the bees with the beeswax scent).
Swarms typically look for a new home that’s higher up than ground level, they often land high in trees. Placing your swarm catch box up high, possibly even in the crook of some tree branches, can help a swarm locate the box easier
If your hive hasn’t swarmed yet, but swarm season is approaching, set the trap up ahead of the swarm whenever possible – scout bees will explore their options before the swarm officially occurs.
A ladder & a ratchet strap – As mentioned above, swarms often land in trees, so you’ll want a ladder on hand to get the box up high and a strap (or platform) to keep it up in the tree.
Protective equipment – Even though swarms are incredibly docile and not likely to sting, it still may be possible. Even when capturing a swarm, staying protected is important.
Swarm Catch Lures – Placing a swarm lure inside of whatever box you are hoping to capture them in can help scout bees become interested in the space available inside your catch box
Lemongrass Oil – Using lemongrass oil may also work to attract scout bees. Lemongrass mimics many honeybee pheromones and will work in a pinch to lure a swarm into your catch box
A Queen Cage or Catching Tool – When capturing a swarm, it is crucial to ensure the queen is moved safely into the swarm box and/or to their new hive. The remainder of the swarm will follow the queen and her pheromones.
Empty equipment – If you plan to catch a swarm of bees using a nuc box or something smaller than your typical deep hive body, ensure you have empty hive equipment set up and ready. Depending on the size of the swarm and the conditions of nectar/pollen availability, you may need tohive them into a two-deep hive setup very quickly to ensure they have enough room.

Hiving a Swarm of Honeybees

Installing a swarm of bees into a new hive is fairly straightforward. If you were able to get the queen separated in a queen cage or catching tool, you can place her inside the new hive and watch as the bees make their way inside to her. You’ll also see other bees start fanning the pheromones around so that everyone can find their way inside and get back to their queen.

If you weren’t able to separate the queen, you can shake the entire colony of bees into the box, like you would if installing a package of bees. The queen should fall with the remainder of the colony and the same process as above will take place until all bees have marched into their new space.

A Caution on Catching Swarms NOT from your Apiary!

As you progress throughout your beekeeping career, especially if you are a part of a local beekeeping club, you may be the one that people think of and call if they see a honeybee swarm. You may even decide to sign up to be added to a “Swarm Catchers” list so that you get contacted to collect possible honeybee swarms.

Though catching a swarm has the obvious benefit of gaining “Free Bees!”, there are a few things to keep in mind:

Swarms are most likely to occur during a time when you’re already busy with caring for the bees that are already in your bee yard!
Bringing a swarm from an unknown source into your own bee yard has the potential to bring pests (like varroa mites) and possible diseases in with it
Swarms from unknown sources should be quarantined away from your current colonies until you learn the health and temperament of the new colony
Swarms are often high up in trees, ensure you have the necessary equipment on hand (see the above section) and take precautions to carefully capture the swarm
