Ant Elimination
Ant Control in Mountain View, CA
101 Exterminators does ant control in Mountain View by going after the colony instead of the trail you can see, SPCB Lic. #9119, Santa Clara County since 2005. Argentine ants (Linepithema humile) run this city, and on the slab-on-grade tracts and Eichlers that make up much of Mountain View they come in at the edge of the concrete, not through a door.
Warning Signs
Signs You Need Ants Service in Mountain View
Species identification, followed by bait placement for slow-acting colony elimination. For carpenter ants — which nest in moisture-damaged wood — we identify and treat the nest location directly. For fire ant mounds, we use targeted mound treatments plus a broadcast perimeter application. Exterior perimeter liquid treatments are applied to prevent re-entry, with interior gel bait placed in active foraging areas.
Foraging trails along baseboards, windowsills, counters, or appliances — especially in kitchen
Live ants in kitchen cabinets, under the sink, near pet food, or around any sugar/food source
Sawdust-like frass near wood — indicates carpenter ant activity inside wood
Visible mounds in lawn or soil beds — fire ant indicator
Large (6–12mm) black ants with bent antennae in bathrooms or attic — carpenter ants
Repeated ant activity despite over-the-counter spray treatments — indicates spray-avoidance in colonies
How It Works
Our Ants Process in Mountain View
Every job follows the same methodical approach — no shortcuts, no guesswork. Here is what to expect when you work with us in Mountain View.
Species Identification
Misidentifying ant species leads to failed treatments. We identify the species present — Argentine, carpenter, fire, pavement, odorous house — before selecting treatment methodology.
Nesting Site Assessment
Carpenter ants nest in wood. Argentine ant colonies can extend across an entire block. Fire ants create visible mounds. Each species nests differently and requires us to find the colony before treating.
Targeted Bait & Barrier Treatment
Slow-acting gel baits are placed in foraging trails — workers carry the bait back to the queen, eliminating the colony from within. Exterior perimeter liquid is applied to prevent new entry.
Follow-Up & Assessment
We return to confirm colony suppression, replenish bait if needed, and treat any secondary colonies that become active as the primary colony is eliminated.
Why 101 Exterminators
Ants You Can Count On in Mountain View
Species-Specific Treatment
Argentine ants, carpenter ants, and fire ants each require a different product and approach. Generic "ant spray" does not work equally for all species.
Bait-Based Colony Elimination
Slow-acting bait reaches the queen through worker activity. This is the only way to achieve lasting colony elimination without returning every few weeks.
Exterior Barrier Prevents Re-Entry
A liquid residual barrier on the perimeter prevents new foragers from adjacent colonies from entering — critical in Argentine ant supercolony territory.
Interior-Safe Methods
Gel bait placement in cracks and crevices does not require broadcast interior spraying. Food and dishware do not need to be removed for interior bait treatments.
Common Questions
Ant Control FAQs for Mountain View
Why do ants come back a few days after I spray them in my Mountain View kitchen?
Because the spray killed foragers, not the colony. Argentine ant supercolonies across Santa Clara County hold many queens in many nests, and repellent products can split those nests into new satellites, which makes the problem bigger. Slow-acting bait works the other way: workers carry it back and feed the brood and queens before it acts. Expect the trail to look busier for a day or two after baiting, that is the bait moving.
Ants are coming out of the baseboard in my Monta Loma Eichler: where is the nest?
Almost certainly outside, in soil against the slab or under the adjoining hardscape. Eichlers are slab-on-grade with radiant tubing in the concrete, so ants appearing at a baseboard have usually traveled the slab edge and come up through an expansion joint or a plumbing penetration rather than nesting inside the wall. Finding that exterior trail, whether that is an atrium bed, a planter strip or a driveway seam, is what makes the treatment hold.
Do ants get worse in Mountain View when it rains?
The first heavy storms of the season are the biggest single ant push of the year here. Argentine ants nest shallow, rain floods those nests, and they move up and inland, often into a kitchen or bathroom the same week. The dry stretch in mid-summer produces the second wave, when they come in for moisture. Treating ahead of the November rains works better than reacting to a trail in December.
