How beekeepers catch a swarm

Beekeepers usually catch a honey bee swarm by placing a box, bucket, or empty hive under the clustered bees, then shaking, snipping, or gently brushing the cluster into that container and moving the bees into a hive. This works because a swarm is a temporary resting cluster, not a settled nest, and it is often calmer than an established colony as long as it is not disturbed. (bees.caes.uga.edu)

Why a swarm can be caught

A honey bee swarm is how a colony reproduces. In spring, the old queen leaves with a large share of the workers, and the bees gather in a temporary cluster while scout bees look for a new home. That hanging cluster may be on a branch, fence, bench, shrub, mailbox, or part of a building. (extension.uga.edu)

That temporary stage is what makes swarm catching possible. The bees have not built comb yet, they are not defending honey stores or brood, and Extension guidance says swarms in this clustered stage are relatively gentle if left alone. Georgia and Tennessee Extension sources say a swarm often moves on within about 24 to 48 hours, which is why swarm calls tend to be time-sensitive. (extension.uga.edu)

For a beekeeper, the goal is simple: get the queen and as much of the cluster as possible into a container, then give the bees a hive box where they can settle. If the queen is in the box, the rest of the bees usually follow. (bees.caes.uga.edu)

How a beekeeper sizes up the call

Before driving over, an experienced beekeeper usually asks a short list of questions. This helps them decide whether it is really a swarm, whether it is safe to collect, and whether the job is a quick pickup or something more complicated. (mcminn.tennessee.edu)

1. Are these really honey bees? A beekeeper may ask what the cluster looks like, because yellowjackets and hornets are a different problem. If you are not sure, use the Swarm, hive or wasps? identifier. (mcminn.tennessee.edu)
2. How long have they been there? Tennessee Extension says that if the bees have been there for more than 2 days, it may no longer be a simple swarm. They may have started building comb and become more defensive. (mcminn.tennessee.edu)
3. How high up are they, and what are they on? A low cluster on a small branch is very different from bees under second-story eaves or near utility lines. Beekeepers may decline a call that is out of reach or unsafe. (mcminn.tennessee.edu)
4. Has anyone sprayed or disturbed them? Extension guidance warns callers not to spray the bees with water, soap, or pesticide and not to disturb the cluster. Spraying or harassing the swarm can make collection harder and can raise sting risk. (mcminn.tennessee.edu)
5. Do they have permission from the property owner? Tennessee Extension specifically advises getting permission from the landowner or homeowner before collecting a swarm. (mcminn.tennessee.edu)

This quick screening is also why some swarm calls end with "wait and watch" instead of "send a beekeeper now." If the cluster is safely away from people and pets, official Extension advice often says the best option is to leave it alone and let it move on by itself. For help finding local contacts, check the state-by-state directory. (extension.uga.edu)

What the beekeeper brings

For a true swarm call, the gear is often pretty basic. Tennessee Extension says a beekeeper may prepare a container or hive body, 1:1 sugar-water syrup in a squirt bottle, a smoker with fuel and matches, a strap to secure the box, a bee veil, and sometimes a ladder. (mcminn.tennessee.edu)

University of Georgia Extension describes one simple method for a safely accessible swarm: use a five-gallon plastic bucket with a perforated cover, mist the swarm with sugar syrup, place the bucket under the bees, then give the branch a sharp shake so the cluster drops in. Other beekeepers prefer an empty hive body or small nucleus box, especially if they want to install the bees directly into their new hive right away. (bees.caes.uga.edu)

Protective clothing still matters. Even though swarms are usually calmer than established colonies, Extension sources still say to treat them with caution and avoid unnecessary disturbance. (extension.uga.edu)

How the actual catch works

The easiest swarm catch is the classic low branch. Tennessee Extension says the beekeeper may lightly mist the cluster and the inside of the hive body or frames with 1:1 sugar-water syrup, then either snip the branch and lower it into the box or position the box below the cluster and shake the branch so the bees fall inside. If shaking is not possible, the bees can be gently brushed or scooped in with a gloved hand. (mcminn.tennessee.edu)

The key moment is getting the queen into the box. Tennessee Extension says the whole cluster, including the queen, should go into the empty hive body or nucleus box if possible. The beekeeper then looks for any missed cluster on the branch and adds those bees too. (mcminn.tennessee.edu)

After that, the beekeeper usually gives straggler bees time to join up. Tennessee Extension advises cracking the lid for a few minutes so late-arriving bees can find the new cluster. Depending on the situation, the box may be moved within minutes, or it may stay until evening or overnight if many bees are still flying around the original spot. Ventilation matters, so the entrance may be screened while the bees are transported. (mcminn.tennessee.edu)

If the swarm is near the beekeeper’s apiary, Georgia Extension says another approach is to remove the branch holding the swarm and shake the bees in front of an empty hive so they walk in and establish a colony there. Either way, the basic method is the same: gather the cluster, protect the queen, and give the bees a safe cavity to adopt as home. (bees.caes.uga.edu)

When a swarm is really a hive problem

Not every "swarm" call is a true swarm. If bees are going in and out of a hole in a wall, chimney, soffit, roofline, or other cavity, or if they have already started building exposed comb, that is closer to an established colony than a temporary cluster. That matters because the job may no longer be a quick pickup. Learn more in A swarm vs. an established hive: why it matters. (extension.uga.edu)

University of Maryland Extension says few beekeepers will retrieve honey bees nesting in a wall void. Removing bees from a structure can require a specialist, and if bees are killed but the nest is not removed, wax and honey can melt, odor can develop, and other pests may be attracted. If you are dealing with bees in a building, Bee cutout and hive removal cost explains why that work is different from a simple swarm pickup. (extension.umd.edu)

Rules and licensing can vary by state or city, especially for structural removals and pesticide use, so confirm the local requirements with the relevant agriculture, pest control, or building office when needed. Swarm pickup is also not always free: North Carolina and Georgia Extension sources note that not all beekeepers collect swarms, and some may charge a fee. (rowan.ces.ncsu.edu)

What you should do while waiting for the beekeeper

If you find a swarm, the most helpful thing is usually the simplest: keep a respectful distance and keep other people, children, and pets back. Do not throw anything at the swarm, do not spray it, and do not try to knock it down. If the cluster is in a safe spot, it may leave on its own within a day or two. For step-by-step homeowner guidance, see What to do when you see a honey bee swarm. (extension.uga.edu)

A helpful homeowner checklist:

• Note when you first saw the bees. (mcminn.tennessee.edu)
• Take a clear photo from a safe distance so the beekeeper can help confirm that they are honey bees. (mcminn.tennessee.edu)
• Tell the beekeeper how high the cluster is and what it is attached to. (mcminn.tennessee.edu)
• Make sure gates are unlocked and pets are secured before the beekeeper arrives. (mcminn.tennessee.edu)
• If the bees are entering a wall or roof cavity, say that up front so the beekeeper knows this may not be a simple swarm call. (extension.uga.edu)

Frequently asked questions

Do beekeepers always remove swarms for free?

No. Cooperative Extension sources say some beekeepers collect swarms for free, while others may charge a fee, especially if the location is difficult, far away, or not a simple pickup. Ask when you call. (rowan.ces.ncsu.edu)

Is it safe to catch a swarm without experience?

Usually not. Even though swarms are often calmer than established colonies, Extension guidance still says to treat them with caution, and CDC guidance warns that people with venom allergy can have anaphylaxis, which is a medical emergency. A local beekeeper is the safer choice. (extension.uga.edu)

What if the bees have been there for several days?

That may mean it is no longer a simple resting swarm. Tennessee Extension says that if the bees have been in place for more than 2 days, they may have started building comb and may behave more like an established colony. (mcminn.tennessee.edu)

What should I do if someone gets stung near a swarm?

CDC says to wash the area with soap and water, remove the stinger by wiping gauze over it or scraping with a fingernail, apply ice, and watch for signs of an allergic reaction. If the person has trouble breathing or other severe symptoms, get emergency care right away. More detail is in Bee sting first aid and when to get help. (cdc.gov)
