On a warm morning in Chandler, a trail of tiny ants marching across the sidewalk is as normal as a hummingbird at the feeder. Whether those ants remain outside or head for your kitchen depends on the species, the moisture around your house and how many ways they can find in. A short list of species accounts for nearly every ant call in the city.
The usual ant species
Argentine ants are small, brown and tireless. They form super-colonies that can span entire blocks, following sprinkler lines and shaded foundations and often moving indoors in summer for water. Harvester ants are big red or brown ants that clear bare patches around their nest entrances in gravel, desert landscaping and vacant lots; they are common near the Gila River Indian Community boundary and open desert parcels. Fire ants occur here too and defend mounds with a painful sting. Pavement ants nest in slab cracks and sidewalks, and tiny pharaoh or ghost ants can establish themselves inside buildings, especially apartments, where they are hard to eradicate without professional baits.
Why Chandler is so ant-friendly
Almost every yard in Chandler is irrigated, and that moisture lets ants thrive in an otherwise dry environment. Lakes in Ocotillo and Sun Lakes, drip systems under rock mulch, leaking hose bibs and pool decks all provide water. Citrus trees and oleanders host aphids and scale insects whose honeydew feeds ants and encourages them to nest nearby. In the hottest months, ant trails shift toward kitchens and bathrooms. After monsoon storms, flooded colonies move to higher ground, which can mean your patio or garage.
How providers deal with them
- Identify the species by examining the ants and following trails to the entry points.
- Use slow-acting baits for Argentine, pharaoh and similar trailing ants so workers carry the product back to queens.
- Apply a perimeter treatment around the foundation, block walls and landscape edges.
- Treat harvester and fire ant mounds directly or with granular baits.
- Advise on fixing irrigation leaks, removing debris and sealing cracks.
Patience matters. Baits can take days or weeks to collapse a colony, and a sudden increase in ant activity at first can mean the bait is working.
What you can do now
- Wipe trails with soapy water and avoid spraying near baits.
- Keep sugary foods, pet bowls and compost sealed.
- Pull rock and mulch back from the stucco.
- Trim plants that touch the wall or roof.
- Fix leaking spigots, drip emitters and pool equipment.

Ant questions in Chandler
Why do ants keep coming back after I spray?
Sprays kill what they touch but not the queens. Baits and barrier treatments reach the colony.
Are fire ants common in Arizona?
Fire ants do occur in the Valley, especially in irrigated areas, and their stings can be painful.
Why do I see ants after it rains?
Wet soil forces colonies to relocate, and structures offer dry shelter.
Do ants damage stucco or tile?
They rarely damage materials but can nest in voids and bring contamination to kitchens.
