As the desert heat starts to climb and flowers bloom across Maricopa County, ant colonies become increasingly active. Spring marks the beginning of a busy season for homeowners. You may notice trails of ants in their kitchens, bathrooms, or around outdoor patios. The combination of warmer weather, spring rains, and new food sources drives ants to forage. To reproduce and sometimes invade homes in search of sustenance and shelter.
This comprehensive guide explores why ant activity surges in spring. How to identify common species. What you can do to prevent infestations, and when to call in professional help.
Why Ant Activity Increases in Spring
Warming Temperatures Trigger Foraging
Spring temperatures across Arizona range from the mid-60s to high 90s. This warmth stimulates ant metabolism and signals their colonies to begin foraging. Ant scouts venture further to find food, creating trails that lead them indoors.
Spring Rains Disrupt Outdoor Nests
Rainfall during early spring months can flood ant nests, especially those near the surface. This forces colonies to relocate, sometimes migrating toward drier, protected spaces inside homes.
Ants Seek Moisture and Food Indoors
The dry desert climate means moisture is a valuable resource. Kitchens, bathrooms, and laundry rooms often provide both water and food, making them prime targets for spring ant invasions.
Common Spring Ants in Maricopa County
Odorous House Ants
These small, brownish-black ants give off a musty odor when crushed. They are particularly active in spring and are drawn to sweet foods and moisture sources like sinks and leaky pipes.
Pavement Ants
Typically nesting under driveways, sidewalks, and patios, pavement ants can infiltrate homes through cracks in the foundation. They prefer greasy and sweet foods and can be found trailing along baseboards.
Argentine Ants
Known for forming super-colonies, Argentine ants are highly aggressive and difficult to eliminate. They often appear in kitchens and bathrooms in large numbers, especially during damp spring months.
Fire Ants
Though less common in urban parts of Maricopa County, fire ants are dangerous due to their painful stings. They may build mounds in open lawns or dry soil near foundations.
Harvester Ants
More common in outdoor areas, harvester ants collect seeds and are known for creating visible, flat mounds in yards. They typically don’t invade homes but can pose a threat in outdoor living spaces.
Where You’ll Find Ants in the Spring
- Kitchens and Pantries: Ants often follow food crumbs, sticky spills, or sugary residues. Scout ants leave pheromone trails leading others directly to these sources.
- Bathrooms and Sinks: Moisture-rich areas like sinks, tubs, and behind toilets attract ants looking for water, especially odorous house ants.
- Baseboards and Wall Cracks: Small cracks and entry points along walls, baseboards, or window seals make it easy for ants to sneak into homes.
- Patios, Foundations, and Driveways: Outdoor nesting ants like pavement or harvester ants may begin their colonies near home foundations, eventually making their way inside.
How to Prevent Spring Ant Infestations

Use caulk or weather-stripping to seal:
- Window and door gaps

- Rinse recycling and keep bins clean.

Apply Natural or Chemical Barriers
- Spray citrus oil, vinegar, or peppermint oil as deterrents.
- Use perimeter pesticide sprays labeled for ant control.

“Springtime in Glendale is beautiful, but I used to dread the ants that came with it! Last year, they invaded our picnic, and it was such a hassle. This year, I decided to be proactive.
