Native bees in Arizona — plant the bloom, then leave them somewhere to nest.
The Sonoran Desert supports an unusually rich native bee fauna, and most of those bees are solitary and non-aggressive — nothing like the defensive colony behavior people picture. They also do not live in hives. If a yard has flowers but no nesting habitat, it is a rest stop, not a home. Habitat is the half that almost every pollinator guide skips.

01
Bloom that spans the year
- Spring is easy in the desert; summer and late fall are where most yards go blank.
- Spring: brittlebush, globe mallow, penstemon, palo verde, and desert marigold.
- Summer: desert willow, salvias, Mexican honeysuckle, and the bean-family trees.
- Fall: Mexican bush sage, chuparosa, aster relatives, and rebloom on the salvias.
- Plant in drifts rather than one-of-everything — a solitary bee works a patch, not a specimen.
- Keep single-flowered forms. Doubled ornamental hybrids often carry little accessible pollen.
02
Ground nesting — most native bees do this
- The majority of native bee species nest in bare, undisturbed soil, not in boxes.
- Leave open patches of bare, sunny, well-drained ground somewhere in the yard.
- Landscape fabric and wall-to-wall gravel eliminate ground nesting habitat completely.
- Avoid tilling or scraping the same bare patch every season.
- Small dirt mounds with a pencil-width hole are nests, not pests — leave them alone.

Cavity nesting and bee hotels
- Leafcutter and mason bees use hollow stems and beetle holes in dead wood.
- Leaving standing dead stems and a piece of untreated dead wood does more than most purchased hotels.
- If you use a bee hotel, it must be cleanable — dirty, permanent tube blocks concentrate parasites and disease.
- Mount it in morning sun, sheltered from afternoon heat and rain, and take it down for cleaning between seasons.
- Round leaf-edge cuts on your roses or redbud mean leafcutter bees are working. That is a success, not damage.
04
Water, chemicals, and timing
- Shallow water with landing surfaces — pebbles, gravel, a sloped saucer — refreshed every day or two.
- Never apply insecticide to an open bloom, and treat in the evening when bees are not foraging.
- Systemic neonicotinoid products move into pollen and nectar; skip them on pollinator plants.
- Delay hard cutbacks of stems until spring so overwintering bees can emerge.
- A yard that tolerates some chewed foliage is a yard that keeps predators and pollinators alive.
05
Honey bees, swarms, and safety
- Africanized honey bees are established in Arizona, and colony removal is not a DIY job.
- A cluster hanging on a branch is usually a resting swarm; an established colony inside a wall, water meter box, or irrigation valve box is the one that needs professional removal.
- Do not spray, seal, or disturb an established colony — call a licensed removal service.
- Seal wall voids, water meter boxes, and equipment cavities as prevention rather than treatment.
- Solitary native bees are a different situation entirely; they have no colony to defend and rarely sting.
FAQ
Common questions.
Most native bees are solitary and have no colony to defend, so they are unlikely to sting and many species cannot deliver a meaningful sting at all. The defensive stinging behavior people fear comes from honey bee colonies, which is a separate concern handled by professional removal.
They help cavity-nesting species when they are maintained. An uncleaned hotel left up year after year concentrates parasites and disease and can do more harm than good. Choose a cleanable design, mount it in morning sun, and remember that most native bees nest in the ground and need bare soil instead.
Because the majority of native bee species nest in undisturbed soil. Wall-to-wall gravel over landscape fabric leaves them nowhere to go. A few sunny, well-drained bare patches tucked into the planting design costs nothing and supports the bees your flowers are attracting.
Keep people and pets away and call a licensed bee removal service. Arizona has established Africanized honey bees, so removal of an established colony — inside a wall, a water meter box, or an irrigation valve box — is not a do-it-yourself project, and spraying or sealing it usually makes the situation worse.
That is a leafcutter bee, and it is a good sign. She uses those leaf discs to line her nest cells. The plant is not harmed in any meaningful way, and the same bee is pollinating the rest of your garden.
