A paper wasp is a social wasp in the genus Polistes. It builds an open, paper honeycomb nest, often under a protected overhang. It can sting, so the useful next step is to keep people and pets away from the nest while you decide if its location creates a sting risk.
Paper wasps are among the more visible wasps in the Sonoran Desert. They are social insects, so one nest may hold a queen early in the season, then workers later on. Those workers hunt caterpillars, gather material for paper nest growth, and collect water to cool the nest.
A paper wasp nest usually starts in a sheltered spot. Natural sites include rock cracks and thick plant growth, such as dead fan palm leaves. Around homes, the same kind of cover can be found under roof overhangs, patio covers, or other protected edges.
The nest itself is a strong clue. Paper wasps make a small paper comb with open hexagonal cells, suspended from a narrow stalk. If you can see the cells from below, you’re likely looking at a paper wasp nest rather than a bee hive.
Finding one wasp inside the house usually means it wandered in from outside. Finding repeated wasps near the same patio, door, or roofline points to a nearby nest. Give that area room.

- Smooth, shiny body

Health risk
Paper wasps can sting if the nest is disturbed or they feel threatened. Some people can have allergic reactions to wasp stings. If someone is stung, call Poison Help at 1-800-222-1222, or call 911 for severe symptoms. Don’t handle a live wasp or an active nest by hand.
In the Sonoran Desert, a mated queen starts a nest in spring. Colonies grow through late spring and summer, then the old queen and workers die by late fall, leaving the nest empty.
What's different in the Phoenix area
In the Phoenix area, paper wasps often use the same shaded, tucked-away spots they would use in the desert. Dead fan palm skirts, roof overhangs, and small protected gaps can mimic rock cracks or dense vegetation. In summer heat, workers may also be seen gathering water for nest cooling, so a few wasps near a pool or irrigation wet spot may lead back to a nest nearby.

What you can do today
Back up first
Move away from the nest before taking photos or looking closer. Keep kids and pets out of that spot until you know where the nest is attached.
Look from a safe distance
Check eaves, patio covers, shed ceilings, and outdoor fixtures without reaching toward them. Use your phone zoom instead of getting close.
Watch the flight path
Stand well away and note where wasps keep returning. A steady line to one overhang usually marks the nest site.
Don’t knock it down active
Hitting or scraping an active nest can bring stings. Avoid shaking gates, shutters, or patio beams that hold a nest.
Use Poison Help after stings
If someone is stung, call Poison Help at 1-800-222-1222, or call 911 for severe symptoms.
When to call a pest control company
Call a local pest control company when the nest is near a door, play area, patio seating, pool path, mailbox, or any place people must pass close to it. A technician will look for the nest attachment point, the number of active wasps, nearby shelter sites, and whether more than one nest is present. This is also the safer route if the nest is overhead or hard to see clearly.

Common questions about paper wasps in Phoenix
Is a paper wasp nest the same as a bee hive?
No. Paper wasps build an open paper comb with visible hexagonal cells. Honey bees are stockier insects and their colonies are built very differently.
Will the same paper wasp nest stay active all year?
In the Sonoran Desert, the old queen and workers die by late fall, and the nest is abandoned. New mated queens overwinter in protected places, then start the cycle again in spring.
Are paper wasps useful?
Yes, they hunt caterpillars and other small arthropods to feed their larvae. That doesn’t make a nest safe near a doorway or play space.
Can I remove a paper wasp nest myself?
Don’t remove an active nest by hand or by striking it. If it’s close to people, hard to reach, or has steady wasp activity, call a local pest control company.
Why are paper wasps around my patio?
They may be nesting under a protected overhang, or they may be collecting water for cooling. Watch from a distance to see where they return.
