Fresno lies in the heart of California's San Joaquin Valley, one of the most productive farming regions in the country. Summers are long, hot and dry; winters are cool, with dense tule fog; and the canals and irrigation ditches that crisscross the region provide water for orchards, vineyards and backyards. Pests benefit from both the farmland and the city. Rats and ants move between fields and neighborhoods, while termites find ready homes in older wood-frame houses in the Tower District, Fig Garden and Sunnyside.

Common pests across the Fresno area
- Argentine ants, which form huge, interconnected colonies and invade kitchens in dry weather.
- Roof rats and Norway rats, which use fruit trees, palms, fences and canal banks.
- Western drywood termites and subterranean termites, which attack framing, eaves and furniture.
- German, American and Oriental cockroaches, depending on the building and its moisture.
- Black widow spiders, wasps and yellowjackets around yards and outbuildings.
- Bed bugs, which circulate through rentals and hotels.
How the Central Valley climate shapes pest activity
Triple-digit summer days dry out the landscape and push ants, roaches and rodents toward irrigated yards and indoor water. Mild, wet winters in the Valley bring a different set of problems: tule fog and rain soak the ground, causing ants to move indoors and rats to seek attics. Because there is no hard freeze, many pests remain active through winter. Harvest time and orchard activity can also push rats into nearby neighborhoods, particularly on the edges of town in northeast Fresno and Clovis-adjacent areas.
Housing and landscape considerations
Fresno has many 1920s to 1950s bungalows and ranch homes, often with crawl spaces, raised foundations and attic vents. Stucco is widespread. Fruit trees such as citrus, figs and persimmons are common in backyards, as are mature palms. These features supply food and shelter for rats. Large lots in older districts often include sheds, fences and garden beds that can hide pests. Termite swarms and Argentine ant trails are frequent signs for homeowners in spring and summer.
A standard service visit
- Inspection of the yard, fences, trees, roofline, attic and crawl space.
- Exterior treatment to create a barrier against ants, spiders and roaches.
- Rodent trapping and exclusion if signs are present.
- Termite checks of eaves, attic framing and subfloor areas.
- Recommendations for pruning, irrigation and storage.
Prevention
Clear fallen fruit from yards every week. Trim tree limbs from the roof. Fix leaking sprinklers and hose bibs. Seal gaps around plumbing and vents. Store pet food indoors and use lidded trash cans.

Fresno pest FAQs
Why do ants invade during dry weather?
Argentine ants look for water and food indoors when the outdoors dries out.
Are rats in fruit trees a sign of an attic infestation?
They can be. Roof rats often move between trees and attics, so check both.
Do I need a termite inspection for a stucco house?
Yes. Stucco can conceal damage, and drywood termites can infest eaves and attic wood.
How often should I schedule service?
That depends on pest pressure. Many households use seasonal visits.
