Wasps and Bees in Arizona: Identification, Risks, and Safe Removal
Arizona hosts paper wasps, mud daubers, Africanized bees, and more. Learn which are dangerous and when to call a professional.
Common Arizona Wasps and Bees
Africanized Honey Bee
Apis mellifera scutellata hybrid
Appearance: Nearly identical to European honey bee. Golden-brown with dark bands, 1/2 inch, fuzzy body. Cannot be visually distinguished from domesticated bees without lab analysis
Where found: Wall voids, attic spaces, irrigation valve boxes, barbecue grills, overturned pots, vehicle engines, tree cavities, shed interiors -- any enclosed cavity
Danger level: High
Paper Wasp
Polistes spp.
Appearance: Slender body, narrow waist, long legs that dangle during flight. Brown to reddish-brown with yellow markings, 3/4 to 1 inch
Where found: Builds small, open-celled paper nests under eaves, patio covers, fence caps, grill covers, mailboxes, and play equipment
Danger level: Moderate
Mud Dauber
Sceliphron spp.
Appearance: Slender, black or dark blue with a very thin waist, 3/4 to 1 inch. Builds distinctive tube-shaped mud nests on walls, eaves, and ceilings
Where found: Under eaves, porch ceilings, garage walls, storage shed interiors
Danger level: Very low
Tarantula Hawk Wasp
Pepsis spp.
Appearance: Large (up to 2 inches), metallic blue-black body with bright orange wings. Unmistakable
Where found: Desert areas, yard perimeters, open lots near natural desert
Danger level: Low risk, extreme pain
Carpenter Bee
Xylocopa spp.
Appearance: Large (3/4 to 1 inch), resembles a bumblebee but with a smooth, shiny black abdomen (bumblebees have fuzzy abdomens)
Where found: Wood structures -- fence posts, pergolas, deck rails, fascia boards, patio covers
Danger level: Low for stings, moderate for property
Wasp and Bee Activity in the Phoenix Valley
March-June (peak for bees)
Africanized bee swarming season. Swarms cluster on structures while scouts search for nesting sites.
April-October (peak for wasps)
Paper wasp nests grow throughout the season, reaching dozens of wasps by late summer.
Monsoon season (July-September)
Bee colonies may move into wall voids seeking storm shelter. Wasp activity remains high.
Winter (November-February)
Paper wasp colonies die off; only queens survive. Bee colonies remain active with reduced foraging.
Arizona's Africanized bee population is well-established. Feral colonies can establish hives anywhere, including residential structures, with year-round activity.
How Dangerous Are Arizona Wasps and Bees?
Wasp and Bee Prevention Tips
- Inspect in early spring and remove small paper wasp nests before they grow.
- Seal nesting cavities: wall voids, eave gaps, open pipes, and uncapped fence posts.
- Cover and periodically check irrigation valve boxes -- bees commonly nest inside.
- Don't leave sweet food or drinks uncovered outdoors.
- Avoid swatting at bees or wasps -- move slowly and calmly away.
- Stay away from swarms; they usually move on in 1-3 days. Call a pro if they establish on your property.
- Seal carpenter bee bore holes and paint exposed wood -- they prefer untreated wood.
When to Call for Bee or Wasp Removal
- Any bee colony on or near your property (do NOT attempt removal yourself)
- Bees entering a wall void, attic, or enclosed space on your structure
- A bee swarm that has been on your property for more than 48 hours
- Paper wasp nests near doorways, walkways, play areas, or high-traffic zones
- Carpenter bee damage to wood structures
- Anyone in your household has a bee/wasp sting allergy
