Spring in Arizona means desert blooms, rising temps, and—if you’re lucky enough (or unlucky, depending on how you see it)—a front-row seat to bee swarming season. Every year, thousands of homeowners across the Valley are startled to find a buzzing cloud of bees suddenly hanging out in their backyard, near a tree, or on the side of their home.
While it’s easy to panic, bee swarms are a normal part of nature—and more often than not, they’re not aggressive. But that doesn’t mean you should ignore them.
In this article, we’ll explain exactly what to do if you see a bee swarm in Arizona, how to stay safe, and the smartest way to get them off your property—without harming the bees or putting your family at risk.
What Is a Bee Swarm, and Why Is It Happening?
Bee swarms typically happen in the spring, when bee colonies grow too large and need to split. A swarm forms when the queen bee leaves the hive with a group of worker bees to start a new colony elsewhere. As they search for a new home, the swarm might temporarily rest in a tree, on a wall, or even under the eaves of your house.
This cloud of buzzing bees may look intimidating, but it’s actually a natural—and necessary—part of a healthy ecosystem. During this time, the bees are usually not aggressive because they’re not defending a hive full of honey or brood.
According to the University of Arizona Cooperative Extension, bee swarms are most common from March through June, especially following periods of rain that stimulate blooming flowers (and in turn, food for bees).
What to Do If You See a Bee Swarm in Arizona
If you suddenly find a swarm of bees on your property, here’s a step-by-step guide for what to do—and what not to do.
1. Stay Calm and Keep Your Distance
This is the golden rule. Don’t swat at the bees or try to spray them with water or chemicals. That could provoke a defensive reaction.
Instead, keep at least 15–20 feet away and monitor the swarm from a safe distance.
2. Do Not Attempt to Move or Kill the Swarm
Tempted to take matters into your own hands? Don’t. Bee swarms are often temporary and may move on within a few hours to a few days.
Spraying or disturbing the swarm can turn a non-aggressive group into a defensive one—and you don’t want to be on the receiving end of hundreds of stingers.
3. Secure Pets and Children Indoors
If the swarm is in your yard or near an entry point, keep pets and children inside until it moves on or is professionally removed.
Bees are especially sensitive to fast movements, loud noises, or curious poking—which small kids and pets are very good at.
4. Check for Signs of Nesting
If the bees are hanging around longer than 72 hours, they may be trying to establish a permanent hive in your home’s walls, attic, or chimney.
In this case, you need to act quickly before removal becomes more complicated and costly.
5. Call a Bee Removal Professional
If the bees haven’t left within a day or two, or if they’ve started building a hive, call a licensed pest control expert who specializes in bee removal.

Are Bee Swarms in Arizona Dangerous?
Most bee swarms are not aggressive, but that doesn’t mean they’re completely harmless. Arizona is home to Africanized honey bees (also called “killer bees”), a hybrid species known for their heightened defensive behavior.
These bees look nearly identical to European honey bees, but they’re more likely to attack when provoked, especially once they’ve built a hive.
So even if the swarm looks peaceful, it’s best to treat all bee swarms with caution and contact a professional for safe removal.
The Arizona Department of Agriculture encourages residents to avoid handling or disturbing bees and to report swarms or aggressive colonies to pest professionals trained in bee management.
How to Prevent Bee Swarms from Settling on Your Property
While you can’t prevent bees from flying over your yard, there are some steps you can take to make your property less attractive for nesting:
- Seal all cracks and gaps in your home’s exterior, including around vents, eaves, and chimneys
- Use screens or mesh to cover attic openings and wall vents
- Remove clutter like unused appliances, wood piles, or lawn furniture that bees may use for shelter
- Keep garbage cans sealed and clean to reduce food odors that attract foraging bees
