Ant Control & Extermination in Southern California
Ant trails come back because the colony is still there. We treat the colony, then the perimeter they use to get in.
Most ant calls in Southern California are Argentine ants: tiny, dark-brown, and organized into huge interconnected colonies that move indoors in long trails whenever the weather turns hot, dry, or wet. Odorous house ants, carpenter ants, and in some yards fire ants add to the mix. Spraying the trail you can see kills a few hundred foragers and scatters the rest — the colony just sends more, often by a new route.
Fly Guys Pest Control identifies the species first, because baits that work on one ant are ignored by another. We then use slow-acting baits the foragers carry back to the queens, pair them with a non-repellent perimeter treatment at the entry points, and point out the moisture, food, and landscaping conditions that keep inviting them in.
Signs You Need Ant Control
Trails along counters
Steady lines of ants running along baseboards, countertops, or window frames toward food or water.
Ants after rain or heat
Sudden indoor invasions right after a heat wave or a storm — colonies moving in to escape the weather.
Soil mounds
Small piles of loose dirt in lawn edges, pavement cracks, or planters where a nest has an outlet.
Wood shavings
Fine sawdust-like debris near wood trim or eaves can point to carpenter ants excavating galleries.
Ants in the bathroom
Ants around sinks, tubs, and wall plates are after water and often nesting inside the wall void.
Stings in the yard
Painful, blistering stings around mounds in sunny areas of the lawn are a warning sign of fire ants.
Our Ant Control Process
Species ID & inspection
We find the trails, the entry points, and the nest sites outside, and identify which ant you are dealing with.
Colony baiting
Species-matched baits placed on active trails so foragers carry them back and the colony itself declines.
Perimeter treatment
A non-repellent treatment along the foundation and entry points, so ants crossing it carry it back rather than detouring.
Prevention advice
We flag the leaks, food sources, and plants touching the house that keep drawing ants back, so the result lasts.
Frequently Asked Questions
Why do the ants keep coming back after I spray?
Store-bought sprays kill the ants you can see and repel the rest, which often splits the colony and pushes the trail somewhere new. Lasting control means reaching the queens with bait the workers carry home, which is what we do.
How long until the ants are gone?
Most trails drop off sharply within a few days of baiting, and colonies decline over the following one to two weeks as the bait works its way through. Seeing ants on the bait at first is a good sign, not a bad one.
Do you treat carpenter ants and fire ants?
Yes. Carpenter ants need their nest located and treated directly, and fire ant mounds are treated in the yard. Both are different from treating the common Argentine ant, which is why we identify the species first.
Is ant treatment safe around kids and pets?
Baits go in enclosed stations or tight cracks away from reach, and perimeter products are applied outdoors along the foundation. Your technician will tell you if any area should be kept clear while it dries.
Can ants be handled as part of regular service?
Yes. Ants are covered by our recurring general pest control, which is the easiest way to keep seasonal invasions from restarting. Call (909) 736-4750 to talk through options.
