Pest Control in West Covina, CA
Straightforward, guaranteed pest control for West Covina and the east San Gabriel Valley.
West Covina is classic post-war San Gabriel Valley: mile after mile of 1950s–1970s tract homes with slab foundations, mature landscaping, and original wood eaves — a combination that produces the valley's two most reliable pest calls, Argentine ants and subterranean termites. Up in South Hills and near the Galster Wilderness Park, homes pick up hillside rodent and spider pressure on top of that.
Fly Guys Pest Control serves all of West Covina, from Woodside Village to the restaurant rows along the 10. We diagnose before we treat, use family- and pet-safe products, and back every job with a 100% satisfaction guarantee — with same-day service available on most emergencies.
What 70 Years of Tract Housing Means for Pests
Slab-on-grade construction was the standard when most of West Covina was built, and it gives subterranean termites a direct route: they enter through hairline slab cracks and plumbing penetrations, invisible until a swarm or a soft baseboard gives them away. The same era's yards are now fully mature — thick ground cover, established sprinkler systems — which supports some of the largest Argentine ant colonies in the valley. When summer heat or winter rain hits, those colonies move indoors in force.
The commercial corridors tell a different story. The dense restaurant clusters around West Covina's shopping centers deal with German cockroaches and flies at commercial intensity, and we service them on recurring schedules with the documentation health inspections require. Hillside neighborhoods in South Hills get the rodent-and-spider profile of homes against open space, and we treat those with exclusion-first plans.

Frequently Asked Questions
Why do ants keep coming back no matter what I spray?
Because store sprays kill the visible trail, not the colony — and Argentine ant colonies in mature West Covina yards can span multiple properties. We use non-repellent products the workers carry back to the nest, which eliminates the colony instead of scattering it.
How would I know if my slab home has termites?
Often you wouldn’t — subterranean termites enter through the slab and work inside walls. Mud tubes on the foundation, soft baseboards, or a spring swarm are the visible signs, but an inspection is the only reliable check. Ours is free.
