Africanized honey bees are widespread in Arizona, and swarm season in a normal year runs from mid-March to late October, with most swarms in May and June. If you find a swarm or a colony, stay back, keep people and pets inside, do not spray it, and call. Phoenix Pest Control answers 24/7 and connects you with a licensed local company.
Key takeaways
- Africanized honey bees are widespread in Arizona, so a swarm or colony on a Phoenix property is a real possibility rather than a freak event.
- In a normal year swarm season runs from mid-March to late October, with most swarms in May and June.
- ABC15 reported that removal calls in peak season can jump from 5 to 10 a day to 30 to 60, which is why scheduling gets tight in the spring.
- The safe response is the same for every case: stay back, bring people and pets indoors, do not spray or hose the bees, never seal a colony into a wall void, and call.
- A swarm resting in the open and a colony settled inside a structure are different jobs, and the equipment, the effort and the price differ between them.
- This page does not say who licenses or oversees bee removal in Arizona, because that could not be confirmed; ask any company how it works and what it will quote before it starts.
When is swarm season for Africanized bees in Phoenix?
In a normal year, swarm season runs from mid-March to late October, and most swarms come in May and June. Africanized honey bees are widespread in Arizona. ABC15 reported that peak-season removal calls can climb from 5 to 10 a day to 30 to 60, so expect busy schedules in late spring.
The window is wide. The first swarms appear in March, the busy stretch is May and June, and bees can still turn up in October. That means the safest assumption for most of the year is that a cluster of bees on your property is a possibility, not a surprise.
The phrase "in a normal year" matters. Seasons shift with the weather, and no source here gives a date that holds for every year. Use the months as a guide to how alert to be, not as a guarantee that a sighting in July or September is something else.
The jump from a handful of removal calls a day to dozens explains the one thing homeowners notice about the season: waiting. A swarm that is a minor job in January is a long phone queue in May. The phone line is answered 24/7, visits are set the same day when a technician is free, and no arrival time is promised. For a month-by-month view of everything else that is active, see the Phoenix pest calendar.
What is the difference between a swarm and a colony?
A swarm is a cluster of bees that has left a hive and is resting somewhere temporarily, such as a branch or fence. A colony is a group that has settled into a place, such as a wall void, soffit or meter box, and is building a nest there. The two call for different equipment and different pricing.
People use the words loosely, and the difference matters to the technician more than to you. A swarm in the open is a group in transit. A colony inside a structure is a group that has moved in, and removal can mean opening part of the building to reach it.
You cannot always tell which one you have from the yard. A ball of bees on a mesquite limb is easy. A line of bees entering a crack in stucco, or a hum coming from a wall, points to a colony. Either way, the bees are not yours to inspect up close, and the description you give by phone is what lets the technician decide what to bring.
A swarm that rests on a branch does not always stay there, and a colony that has settled does not leave on its own. Treat both as reasons to call, and describe the location, the height, whether bees are clustered or entering a gap and where people and pets are in relation to them.
| What you see | What it can suggest | First move |
|---|---|---|
| A ball of bees hanging from a branch, fence or chair | A swarm resting in the open | Move away, bring people and pets in, and call |
| A steady line of bees entering and leaving a hole in a wall, eave or meter box | A colony that has settled into a structure | Stay back, do not block the hole, and call |
| A low hum from a wall, soffit or chimney | A possible colony out of sight | Keep clear of that wall and call |
| Many bees circling one spot on the house in spring | Scouts, a forming swarm or an entrance nearby | Keep people away from that area and describe it by phone |
| Bees gathering at a pool edge, hose bib or drip line | Bees collecting water; a hive may be near | Avoid the spot and mention it when you call |
What should you do in the first few minutes?
Move away calmly, bring children and pets indoors, and close doors and windows. Keep everyone back from the cluster or the entrance, and tell neighbors and workers on the property. Then call and describe where the bees are. Do not go back for a better look or a photo.
The urge to get closer is the biggest risk with a swarm that looks docile. A hanging cluster can seem harmless, so people lean in, walk a dog past it or let a child look. Resist all of it, and make sure no one else wanders into the area, including a landscaper, a pool service or a delivery driver.
Think about who is nearby, not only about yourself. Pets left outside are exposed, and a dog on a leash can drag you toward the cluster. Bring animals in first, then adults and children, and shut the doors.
When you call, give the person on the line the facts they need: where the bees are, how high, whether they are clustered or entering the structure, and whether anyone has been stung or is allergic to stings. Say so right away if someone has been stung several times.
- Walk away from the bees without swatting at them, and go indoors.
- Bring children and pets inside and close doors and windows.
- Warn anyone about to walk or work near the spot.
- Note the exact location, height and whether the bees are entering something.
- Call, and tell the dispatcher about allergies or stings.
- Watch from a window if you want to confirm the location, not from the yard.
What should you never do to a swarm or colony?
Never spray it with a hose, wasp spray or insecticide, never knock it down or throw anything at it, never block or seal an entrance, and never go near it to look. Do not try to remove it yourself. Each of these makes agitated bees more dangerous, and sealing a colony into a wall leaves the problem inside.
The sealing mistake deserves its own explanation, because it feels responsible. You see bees going into a hole in the wall, so you fill it with caulk or foam. The bees do not vanish. They are now inside the structure with no planned way out, and the colony is still in your wall. Removal comes first, and the opening is closed afterward, when a technician has dealt with the bees and decided what repair is needed.
A hose or a can of wasp spray fails for a related reason. Neither is designed for a mass of bees, and both give the bees a reason to act on the nearest target, which is you. Smashing a cluster with a broom or a stick does the same. People who try this are the people who get stung many times, and a person who is stung many times needs medical care before anything else.
If you have already done one of these things, do not go back out to fix it. Go inside, keep others away, and tell the dispatcher what happened so the technician arrives expecting it.
What does a technician do, and what are the limits?
A technician assesses from a distance whether it is a swarm or a colony, wears protective gear, explains the plan and price, removes the bees, and then deals with the opening so another swarm is not drawn to the same spot. Limits: access may require opening part of a structure, and repairs are often a separate job.
The visit starts with the phone description. On arrival the technician looks at the situation before approaching: how many bees, how high, whether they are in the open or inside something, and who is nearby. That assessment decides which job this is. A swarm on a low branch is a different afternoon from a colony behind a soffit.
Removal uses suits and equipment made for the work. The technician explains the approach and the price before starting, and with a colony in a structure, says what has to be opened and what that involves. After the bees are gone, closing the gap matters, because the same spot can draw another group. That can overlap with exclusion and sealing, which is where the job of closing the entry belongs.
The limits are worth knowing in advance. No technician can promise that bees will never come back to a property in a region where they are widespread. Opening a wall and repairing it may be priced separately from the removal. And what each case costs is quoted on site, since no price range for bee removal in Phoenix has been sourced for this site. For the full service description, read the bee swarm removal page.
How do you tell a bee problem from a wasp or hornet problem?
You cannot reliably tell them apart from a distance, and you should not go closer to check. Describe what you see, where it is and how the insects behave, and let the person on the phone sort out which service applies. Wasp and hornet nests and honey bee colonies call for different approaches.
This guide does not offer a way to tell an Africanized bee from any other bee by sight. The sources behind it do not give one, and a field mark that only works from a short distance is not something to test in your own yard. What you can describe, safely, is behavior and place: a cluster or a trail, an open branch or a hole in a wall, a hum or silence, early morning or late afternoon.
That description is enough for a dispatcher to help sort the call. A nest hanging under an eave is a different job from a colony in a wall, and wasp and hornet removal covers the first. If you are unsure which you have, call and say so; that is a normal call to make.
How do you lower the chance of the next swarm?
Close small openings in walls, eaves and meter boxes, repair damaged stucco, and ask the technician to seal the entry after removal. You cannot make a property unattractive to every swarm, but you can reduce the number of gaps a colony can use. Do not seal a hole until any bees inside have been dealt with.
A swarm looks for a place to settle, and a gap in a wall, a hollow in an old fixture or an unused box on the property can look like a home. Walk the exterior once a year, before March, and note gaps around utility penetrations, vents, soffits and meter covers.
Think about timing. Sealing is something you do in the quiet months, or the step a technician takes after removal, not something you do during a sighting. Keep a short list of what you saw, such as bees at a hose bib or a trail at a corner, and share it when you call.
Before you hire anyone, ask a few direct questions. Does the company remove the bees or only treat them? Who closes the opening afterward? What is quoted before work starts, and what is quoted separately? Is there any limit on what can be done from the outside? A clear answer to each is better than a low number with no explanation.
Frequently asked questions
Does a swarm in my yard mean I will have a colony in my house?
No. A swarm is a group resting between places and may move on, while a colony has settled in. But a swarm can settle into a gap, so do not wait to see. Keep clear, call, and describe where the bees are and whether they are entering anything.
Is a swarm more dangerous than an established colony?
Neither is safe to approach. The sources behind this guide do not rank them for danger, and the advice is the same: keep people and pets away, do not spray, and call. What differs is the technician’s job and price, not the need to stay back.
What if the bees are on my neighbor’s property?
The same rules apply: stay back, keep your people and pets indoors, and do not approach to look. Tell your neighbor what you saw and where, since they may not know. You can also describe the location when you call, which helps whoever ends up handling it.
What should I do if my pet is stung?
Move the animal indoors away from the bees, and call a veterinarian promptly, because pets can react badly to several stings. Do not wait for symptoms to appear. For people, call Poison Help at 1-800-222-1222 about stings, and call 911 for trouble breathing or facial swelling.
Can I wait until the bees leave on their own?
A resting swarm sometimes moves on, but you cannot count on it, and a colony inside a structure stays. Waiting means someone may walk into the bees in the meantime. If a cluster is near a door, a play area or a path, call rather than watch.
Do I need to be home when the technician arrives?
Not always, but say so when you call. For a swarm in a yard, access to the area matters more than your presence. For a colony in a structure, the technician may need to see the spot and discuss what has to be opened, so being reachable by phone is useful.
