Discovering a bee swarm on your property can be alarming. Thousands of bees clustered together create an intimidating sight, but understanding bee swarm behavior and knowing how to respond safely is crucial. Across Washington, Idaho, Oregon, and Arizona, bee swarms are a natural part of honey bee reproduction, and professional removal protects both your family and these essential pollinators.
Understanding Bee Swarms
What Is a Bee Swarm?
A bee swarm is a natural reproductive process where a honey bee colony splits. When a hive becomes overcrowded or conditions are favorable, the old queen and approximately 50-60% of the worker bees leave to establish a new colony.
The Swarming Process:
- Preparation: Worker bees prepare the old queen to fly by reducing her feeding
- Departure: The queen and thousands of workers leave the hive simultaneously
- Temporary clustering: The swarm lands on a nearby object (tree branch, fence, building) while scout bees search for a permanent home
- Scout search: Scout bees explore potential nesting sites (hollow trees, wall voids, attics)
- Relocation: Once scouts agree on a location, the entire swarm moves to the new site
Swarm Characteristics
- Size: Can range from softball-sized to basketball-sized or larger (10,000-30,000 bees)
- Shape: Typically forms a dense, oval cluster
- Location: Often on tree branches, but can land on fences, mailboxes, vehicles, buildings
- Duration: Usually stays 24-48 hours, but can remain several days in poor weather
- Behavior: Generally docile (bees are full of honey and focused on protecting the queen)
Why Swarms Are Usually Docile
Swarming bees are typically less aggressive than bees defending an established hive because:
- They have no brood (baby bees) or honey stores to defend
- They've gorged on honey before leaving, making them lethargic
- Their primary focus is protecting the queen and finding a new home
- They're in a vulnerable state and prefer to avoid conflict
⚠️ Important Safety Note:
While swarms are generally docile, they can still sting if threatened. Never attempt to remove a swarm yourself. Disturbing the cluster can trigger defensive behavior, and even docile European honey bees can attack in large numbers.
In Arizona: Africanized honey bees (killer bees) are common and extremely aggressive. Swarms may appear identical to European honey bees but can attack with minimal provocation. Always assume swarms in Arizona are Africanized and call professionals immediately.
Bee Swarm vs. Established Hive
| Feature | Swarm | Established Hive |
|---|---|---|
| Duration | Temporary (24-48 hours) | Permanent until removed |
| Location | Exposed (tree branch, fence) | Enclosed (wall void, attic, tree hollow) |
| Visibility | Fully visible cluster | Bees entering/exiting small opening |
| Activity | Relatively calm, clustered | Constant traffic in/out |
| Comb | No comb present | Honeycomb built inside cavity |
| Removal | Easier, less invasive | Complex, may require structural work |
What to Do If You Find a Bee Swarm
Immediate Actions
- Keep your distance: Stay at least 10-20 feet away from the swarm
- Keep others away: Warn family members, neighbors, and pets
- Don't disturb the swarm: No loud noises, vibrations, or water spray
- Avoid the flight path: Bees may be flying to and from the swarm
- Call a professional immediately: Contact a bee removal specialist or pest control company
- Monitor from a distance: Note any changes in swarm behavior or location
What NOT to Do
- Don't spray with water or pesticides: Will agitate bees and trigger defensive behavior
- Don't try to knock down the swarm: Extremely dangerous
- Don't use smoke or fire: Can cause bees to attack
- Don't wait for the swarm to leave on its own: It may move into your home's structure
- Don't attempt DIY removal: Even with protective gear, untrained individuals risk serious injury
- Don't seal the swarm in: If on a building, don't block their exit
🚨 Emergency Situations:
Call 911 if:
- Someone is being attacked by bees
- Someone with bee sting allergies is stung
- Multiple people are stung (10+ stings)
- Bees are exhibiting aggressive behavior (chasing, attacking without provocation)
In Arizona: Africanized bees can pursue victims for 1/4 mile or more. If attacked, run in a straight line to enclosed shelter, covering your face. Do not jump in water-bees will wait for you to surface.
Professional Bee Swarm Removal
The Removal Process
Step 1: Assessment
- Identify bee species (European honey bee vs. Africanized in Arizona)
- Assess swarm size and location
- Determine accessibility and removal method
- Evaluate safety risks to people and pets
Step 2: Preparation
- Don full protective gear (bee suit, veil, gloves)
- Set up equipment (bee vacuum, collection box, smoker)
- Establish safety perimeter
- Prepare relocation hive or transport container
Step 3: Removal
Method 1: Bee Vacuum (Most Common)
- Use specialized low-suction bee vacuum to gently collect bees
- Vacuum bees into collection box with screened ventilation
- Ensure queen is captured (critical for successful relocation)
- Collect as many bees as possible
Method 2: Box Collection
- Position collection box directly under swarm
- Shake or brush swarm into box
- Secure box once queen and majority of bees are inside
- Allow stragglers to join swarm in box
Method 3: Cut and Remove (for swarms on branches)
- Carefully cut branch supporting swarm
- Lower branch into collection box
- Shake bees into box
- Seal and transport
Step 4: Cleanup
- Collect any remaining bees
- Remove any pheromone traces (prevents future swarms)
- Inspect area for stragglers
- Provide recommendations to prevent future swarms
Step 5: Relocation
- Transport swarm to safe location (beekeeper, rural area, bee sanctuary)
- Transfer bees to permanent hive box
- Provide food and water during transition
- Monitor for successful establishment
Why Professional Removal Is Essential

Common Species: Africanized honey bees (killer bees) are widespread
Behavior: Extremely aggressive, attack with minimal provocation, pursue victims long distances
Safety: Assume all swarms are Africanized-never approach
Removal: Requires specialized training and equipment; extermination may be necessary for public safety
Legal Requirements: Some Arizona municipalities require licensed professionals for bee removal
Bee Swarm Myths vs. Facts
❌ Myth: Swarms will leave on their own, so just wait.
✅ Fact: While swarms are temporary, they may move into your home's walls, attic, or chimney if not removed promptly. Once established, removal becomes far more complex and expensive.
❌ Myth: Spraying bees with water will make them leave.
✅ Fact: Water spray agitates bees and can trigger defensive behavior. It won't make them leave and may cause them to attack.
❌ Myth: All bee swarms are dangerous.
✅ Fact: European honey bee swarms are generally docile. However, Africanized bees (common in Arizona) are extremely aggressive. Always treat swarms as potentially dangerous and call professionals.
❌ Myth: Beekeepers will remove swarms for free.
✅ Fact: While some beekeepers collect swarms, many charge for the service, especially for difficult removals. Availability varies, and response time may not be immediate. Professional pest control companies offer guaranteed same-day service.
