How to Catch a Bee Swarm: Step-by-Step Safety Guide

Quick Answer: A bee swarm hanging on a branch is usually docile and relatively easy to collect — wear protective gear, position your collection box beneath the cluster, give the branch a sharp shake, and the bees will fall in. Close the box, move it to your apiary, and install the swarm in a prepared hive before dark. Most of the work is preparation and timing, not physical effort.

What Is a Bee Swarm and Why Do Bees Swarm?

A swarm is a natural reproductive event in honey bee colonies. When a hive becomes overcrowded in spring or early summer, the old queen leaves with roughly half the worker bees to find a new home. Before leaving, scout bees have already been searching for potential nest sites.

The swarm typically leaves the parent hive in a noisy, swirling cloud and settles on a nearby tree branch, fence post, or structure within minutes. The bees cluster tightly around the queen in a football-shaped mass. They remain in this temporary resting spot while scout bees continue searching for a permanent cavity — a hollow tree, an empty hive box, or unfortunately sometimes a wall or attic.

Swarms are not aggressive. The bees have gorged on honey before leaving and have no brood, no honey stores, and no home to defend. They are among the most docile bees you will ever encounter. That said, a cloud of 20,000 free-flying bees is still a lot of bees, and a swarm is a resource opportunity you don’t want to waste.

When Is Swarm Season?

Swarm season in most of the United States runs from March through June, with peak activity in April and May. The exact timing depends on your climate zone:

• Southern states (Texas, Florida, California): Swarming can begin as early as February
• Mid-Atlantic and Midwest: Peak swarming in late April through May
• Northern states and Canada: Swarming typically starts in May and can extend into June

Bees swarm on warm, sunny days — usually between 10am and 2pm — often following several days of warm weather after a rain period. The colony needs enough population, enough food stores, and enough warm days for the bees to build up and trigger the swarming impulse.

Check your beekeeping calendar for region-specific timing, and make sure your hive equipment is ready before swarm season begins.

What You Need Before Catching a Swarm

Having the right gear assembled before you get a swarm call makes the difference between a smooth collection and a stressful scramble. Here is your swarm-catching kit:

Protective Gear (Essential)

Even though swarms are docile, wear full protection. A single bee that gets caught in your sleeve or veil can trigger defensive behavior in the rest of the cluster.

• Bee suit with veil — A full suit provides the most protection. A ventilated suit like the USKEEPERS 3-Layer Ultra Ventilated Bee Suit is a solid choice for warm-weather swarm catching since you will be standing outside for 30–60 minutes. For a more detailed breakdown, see our bee suit guide.
• Gloves — Leather beekeeping gloves or thick rubber gloves. Some experienced beekeepers skip gloves for swarm work, but beginners should always wear them.

Collection Equipment

• Collection box — A nuc box is ideal. Alternatively, a sturdy cardboard box, a five-gallon bucket, or a BeeCastle wooden nuc box works. The box needs a lid or cover and ventilation holes.
• Bee smoker — Light it before you approach. Smoke is not always needed for a calm swarm, but having it ready is good practice. See our bee smoker guide for usage tips.
• Branch cutters or pruning saw — If the swarm is on a branch, you will likely need to cut it.
• White sheet or tarp — Place this on the ground beneath the swarm to catch bees that fall and to create a path into your collection box.

Hive Setup at Home

Have a Langstroth hive set up and ready at your apiary before you go catch the swarm. The hive should have frames with foundation or drawn comb, an entrance reducer installed, and a feeder filled with sugar syrup. The faster you can install the swarm, the better their chances of staying.

How to Find a Swarm

Swarms find you more often than you find them. Here is how to get swarm calls:

• Register with local swarm lists — Contact your local beekeeping association and add your name to their swarm call list. Many associations have online forms or Facebook groups.
• Post on neighborhood apps — Nextdoor, local Facebook groups, and Craigslist are where most homeowners post about swarms.
• Let neighbors know — Tell people in your area that you are a beekeeper and will remove swarms for free.
• Set up swarm traps — Bait hives positioned in likely locations can catch swarms before anyone spots them. Swarm traps with lemongrass essential oil as an attractant are effective for drawing scout bees.
• Check your own hives — Walk your apiary during swarm season and look for queen cells. If you find capped queen cells, a swarm may have already left or is about to. For more on swarm prevention, see our guide on how to find the queen.

Respond to swarm calls fast. A resting swarm typically moves on within 24–72 hours.

Step-by-Step: How to Catch a Bee Swarm

This is the main process. Follow each step in order. Read through the entire process once before you go, so you are not figuring things out on-site with 20,000 bees watching.

Step 1: Assess the Situation from a Distance

Before you suit up, look at the swarm from 10–15 feet away. Note the following:

• Size — A swarm the size of a football is a small prime swarm. A swarm the size of a basketball or larger is a strong colony worth catching.
• Location — Branch at head height is ideal. Higher than 15 feet, inside a wall, underground, or in a structure is a job for a professional.
• Species — Confirm these are honey bees. Yellow jackets and wasps also form clusters. Honey bees are fuzzy with amber-to-dark coloring and distinctive pollen baskets on their legs.

If the swarm is in a wall, chimney, or any enclosed structure, do not attempt removal yourself. Call a professional beekeeper who does cutouts.

Step 2: Gear Up and Light the Smoker

Put on your full bee suit, zip every opening, and tuck your pants into your boots. Light your smoker and get good white smoke going. Lay out your white sheet on the ground directly beneath the swarm cluster, and position your collection box on the sheet with the open side up.

Step 3: Smoke the Swarm Lightly

Give the swarm two or three gentle puffs of smoke across the cluster. Wait 30 seconds. This is not to calm them — swarms are already calm — it masks alarm pheromones and gives you a moment to work. Heavy smoking is unnecessary and can actually agitate the bees.

Step 4: Shake the Branch

If the swarm is on a branch, position your collection box directly beneath the cluster. Grab the branch above the cluster with one hand and give it one sharp, downward shake. The entire cluster should drop into the box in a single mass.

If you cannot reach the branch, use a pole or loppers to cut the branch. Lower it slowly into the box. Do not saw or hack — a clean cut or one sharp shake is less disruptive.

Step 5: Check for the Queen

This is the most important step. Look at the bees in your collection box. Within 2–3 minutes, you should see bees orienting toward the box opening, fanning their Nasonov glands to release a pheromone signal that tells the rest of the colony “the queen is here, come this way.”

If bees are flying around confused or rapidly leaving the box, the queen may not be inside. Check the branch you shook — she sometimes clings to the bark and does not fall with the rest. If you spot her, gently brush her into the box.

Step 6: Collect Stragglers

Once the queen is confirmed inside, lean the collection box on its side with the opening near the sheet. Bees that fell on the sheet will walk up and into the box following the queen’s pheromone. Give this 20–30 minutes. Do not rush it.

Step 7: Secure and Transport

Once the majority of bees are inside, close the box. If using a nuc box, close the entrance with screening or a block of foam — the box needs ventilation but the bees should not escape. Transport the box to your apiary as soon as possible. Keep the box upright, in a cool shaded spot in your vehicle. Do not leave bees in a hot car.

Step 8: Install in the Hive

At your apiary, open the collection box and dump or brush the cluster of bees into the center of your prepared hive — directly onto the frames. They will spread out and begin exploring immediately. Close the hive, install an entrance reducer, and set up a feeder with 1:1 sugar syrup to help them draw comb.

Do not open the hive for at least 3 days. The bees need time to settle and begin building. Your first inspection should confirm the queen is present and the bees are drawing new comb.

What to Do After Catching a Swarm

The first week after hiving a swarm is critical. Here is what to focus on:

Feed immediately. A swarm leaves the parent hive with full honey stomachs but no stored food. They need to draw comb fast, which requires a lot of energy. Provide 1:1 sugar syrup in a feeder inside or on top of the hive. Keep feeding until the bees are drawing comb on 3–4 frames.

Inspect on day 3–5. Open the hive and look for the queen. You want to see eggs — tiny white grains standing upright at the bottom of cells. If you find eggs, the queen is present and laying. If you find no queen after 7 days, the colony cannot survive and you need to requeen or combine it with another hive.

Monitor for pests. New swarms are vulnerable to small hive beetles and wax moths because there is no established guard force. Keep the hive strong with reduced entrance, and check regularly for signs of infestation.

Watch the weather. A late-season swarm (June or later in northern areas) may not have enough time to build up for winter. If you catch a swarm after June 1 in a northern climate, feed aggressively and consider combining it with an existing colony if the population is small. For winter preparation, see our winterizing bees guide.

When NOT to Catch a Swarm

Some swarms should be left to a professional or left alone entirely:

• Swarms inside walls, chimneys, or structures — Cutting into walls is a construction job, not a swarm collection. If the colony has been inside for more than a few days, they have already begun building comb and will be harder to remove. Hire a beekeeper who specializes in structural removals.
• Swarms higher than 15–20 feet — Without a lift or ladder setup, do not attempt it. A fall is far more dangerous than any bee sting.
• Swarms on the ground — A swarm clustered on the ground may be a queenless colony or a colony that was sprayed with insecticide. Approach with extreme caution.
• Africanized bee territory — If you live in an area where Africanized honey bees are established (parts of Texas, Arizona, California, Florida, and several southern states), do not approach swarms without confirmed identification and professional equipment.
• If you are allergic — Anaphylaxis is a medical emergency. If you have had a systemic reaction to bee stings, do not attempt swarm catching.

Common Mistakes

Catching without having a hive ready. The swarm needs a home immediately. If you catch bees and then spend three days ordering a hive, they will abscond or die. Set up the destination hive before you leave to collect the swarm.

Shaking the swarm into a box with no ventilation. Bees generate heat fast in an enclosed space. A sealed cardboard box in summer temperatures can kill a swarm in under an hour. Always provide ventilation.

Opening the hive too soon after installation. Inspecting within the first 48 hours can disturb the queen and trigger absconding, where the entire colony leaves the hive. Wait at least 3 days.

Not feeding after installation. Swarms have no food stores in their new location. Without supplemental syrup, they may starve or abscond. Feed 1:1 sugar syrup until they have drawn comb on at least 4–5 frames.

Trying to catch a swarm from a wasp nest. Yellow jackets and paper wasps are far more aggressive than honey bees. If you are not sure whether the cluster is honey bees, look at the body shape — honey bees are fuzzy and robust; wasps are smooth with narrow waists.
