Let’s start by grounding this in real, hands-on experience from running a beehive supply business—no stiff, textbook fluff, just what I’ve learned from 12 years of working with backyard beekeepers, new homesteaders, and even the occasional urban landlord who stumbled on a swarm in their oak tree. Beehive
Last spring, I got a 7 a.m. call from a customer who’d installed three of our Langstroth hives the month before. “The bees are leaving!” he yelped, and I knew exactly what was happening—swarm season hits our area in late April, and by May, it’s like the entire apiary community’s got a swarm on their hands. A beehive swarm is the colony’s way of making a new family: the old queen takes half the worker bees and flies off to find a new home, leaving a new queen behind with the rest to keep the original hive going. It’s not a sign something’s “broken”—it’s just bees being bees. But when it’s your first time seeing it? It’s terrifying.
So, what should you do if a beehive swarms? Let’s break this down step by step, no jargon, no panic. First, hit pause. Swarming bees aren’t usually aggressive. They’re full of honey, focused on finding a new nest site, and their stingers are less likely to deploy because they’re not protecting a brood or a food source. I’ve stood 10 feet from a swarm cluster on a fence rail before, holding a coffee, and the only thing that happened was a bee landing on my sleeve to check if I had a sugar cube. That said, don’t test it—give ’em space. If the cluster is on a low branch, fence, or the side of a shed, that’s temporary. Bees don’t set up their forever home there; they just rest for a few hours (or a day, max) while scout bees check out spots.
Next, mark the spot. Don’t blast a hornet spray or call an exterminator—those chemicals will kill the bees, and swarms are actually great, free beekeeping stock. Our business supplies hives and starter colonies, but a swarm is a perfect, naturally mated group. Instead, grab a tape measure, snap a photo, and note exactly where they are. If they’re high up—say, 20 feet in a maple tree—don’t climb after them. That’s a job for a professional beekeeper or someone who’s got the gear for hive removal, because you don’t want to drop a ladder and get hurt, or agitate the bees into stinging.
Then, decide if you want to catch them. Catching a swarm is way easier than it sounds, especially if they’re in a low, accessible spot. All you need is a nuc box (that’s a small, 5-frame hive we sell here, perfect for new colonies), some lemongrass oil (bees go crazy for that scent—it signals a good home), and a sheet or tarp to catch any stragglers. Wait until the evening, when most bees are back in the cluster, then gently shake the branch into the nuc box. If you can’t reach the branch, put the open nuc box right under the cluster and tap the branch a few times—most bees will fall into the box, and the scout bees will follow. Cover the box, leave a small opening for ventilation, and move it 10 feet away from the original spot (bees fly straight, so moving it even a little keeps them from going back). By morning, you’ll have a small, happy swarm ready to become your new hive. If you don’t have a nuc box yet, that’s where we come in—we’ve got nuc kits stocked and ready to ship, so you don’t have to wait for supplies to catch a swarm.
But what if you don’t want to catch them? If the swarm is in a spot that’s dangerous—like near a playground, or inside a wall of your house—your only other option is to call a local beekeeper who does swarm removal, not extermination. Exterminators kill the bees, which is a waste of a beneficial pollinator, and bad for the environment. A good beekeeper will remove the swarm and often take it to their own apiary, or even sell it to someone who needs a starter colony. We keep a list of trusted local beekeepers on our website, but if you can’t find one, reach out to us and we’ll point you in the right direction.
Now, let’s talk about preventing swarms in the first place, because that’s way better than reacting to one. From our experience as a beehive supplier, swarms happen when a colony gets too crowded. If you’ve got our hives, make sure you’re adding supers (those big boxes where bees store honey) as they grow. A single Langstroth hive can hold 100,000 bees in peak season, and if there’s not enough room for them to build comb, they’ll swarm to make more space. We send our customers a free guide with their hive purchase, outlining when to add supers—usually once the top box is 80% full. Also, do a quick hive check every two weeks in spring. Look for queen cells—those little peanut-shaped things the bees build on the bottom of frames. If you see queen cells, that’s a sign they’re getting ready to swarm. You can either split the colony into two hives (we sell extra frames and queen cages for that) or remove some of the queen cells to calm them down.
I remember a customer last year who ignored our swarm prevention tips. He installed our two medium hives in April, and by mid-May, he had a swarm in his rose bush. He called us panicking, saying he didn’t know what to do, and we walked him through catching it with a nuc box we had in stock. Now that swarm is a thriving hive, and he’s got honey jars on his kitchen counter. It’s a win-win—for him, for the bees, and for the garden, too. Bees are the reason we have 75% of our food crops, so catching a swarm instead of killing it helps keep pollinator populations up, which is something we’re really passionate about here.
Wait, but what if the swarm is already gone? If you come home and the cluster is just a few stragglers left, that means the scout bees found a better spot, and the rest moved on. Don’t worry—those stragglers will find a new hive, or a new swarm will form from another colony. And if you found the original hive, make sure you keep an eye on it. The old queen left with the swarm, so the new queen in the original hive will take a week or so to mate and start laying eggs. You might see her flying around the hive in that time—she’s bigger than the worker bees, and slower. That’s normal, no need to panic.
Another common mistake new beekeepers make: leaving the swarm in the nuc box too long. Once you’ve caught a swarm, move them to a full hive box within a week. The nuc is temporary, and the bees need room to build comb and store honey. We sell complete hive kits with all the frames and supers you need, so you can transition your swarm smoothly without having to run to a store last minute.
I’ve had people ask me, “Should I use a swarm trap instead of catching a wild swarm?” Swarm traps are just boxes baited with lemongrass oil, and they work—if you put them up in early spring, scout bees will find them and bring the whole swarm. But if you’ve already got a swarm on your property, catching it directly is easier. Traps are good for attracting swarms to your yard, but they’re not a replacement for reacting to a swarm that’s already landed.
Let me circle back to the most important thing: swarms are not emergencies. I’ve had customers who called us at 2 a.m. because they saw a swarm in their tree, convinced it was going to attack their kids. By the time we got there, the swarm had moved on, and the only thing they were stinging was a dandelion. Bees don’t want to hurt you—they’re just looking for a new home. The worst thing you can do is call an exterminator; that’s how thousands of healthy bees die every year, when a swarm could be a new beekeeper’s favorite project.
If you’re a new beekeeper and you’ve never caught a swarm before, reach out. We don’t just sell hives—we’ve got a team of experienced beekeepers who are happy to walk you through the process over the phone, or even come help you if you’re local. We know starting with a swarm can feel intimidating, but it’s one of the best ways to build a strong, healthy hive. And if you don’t have a hive yet, our beginner kits come with everything you need—including the nuc box, lemongrass oil, and a step-by-step guide—to handle a swarm when it happens.
At the end of the day, swarming is just part of being a beekeeper. It’s a sign your colony is healthy and growing. The key is to stay calm, give them space, and if you want to keep them, have the right supplies on hand. We stock all the gear you need, from nuc boxes to supers to queen cages, so you don’t have to scramble when a swarm lands. If you’re thinking about starting a beehive, or you’ve already got a swarm and need help catching it, get in touch with our team to chat through what you need. We’re here to make beekeeping accessible, not overwhelming, and swarms are just another chance to help bees thrive.
