Ant Elimination
Colony Elimination, Not Just Ant Removal
Argentine Ants · Carpenter Ants · Fire Ants · All Species
Spraying the ants you see accomplishes little — the colony behind them remains intact and sends out new foragers within days. Effective ant control requires eliminating the colony, which means identifying the species, understanding where it is nesting, and applying the right product in a way that reaches the queen. 101 Exterminators' ant program begins with species identification, because what works for Argentine ants is different from what works for carpenter ants or fire ants.
How We Work
Our Process
Every service follows a structured protocol designed to deliver effective, lasting results — not a temporary fix.
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.
What Sets Us Apart
Why Choose 101 Exterminators
20+ years of service across four Central California counties. CA licensed, insured, and backed by a genuine satisfaction guarantee.
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
Frequently Asked Questions
Why do I have so many more ants in spring and fall?
Argentine ant colonies in Central California follow moisture-driven migration patterns. In spring, colonies expand as new queens are produced. In fall, as outdoor moisture decreases before winter rains, colonies move toward structures in search of water and food. These are the two peak invasion periods, typically March–May and September–November.
How long does ant treatment take to work?
Slow-acting gel bait takes 3–7 days to achieve significant colony suppression as workers transport it to the queen. You may see increased ant activity for 1–2 days as they find and consume the bait. Liquid perimeter barriers begin working immediately. Full colony elimination in a large Argentine ant supercolony can take 2–4 weeks.
Are carpenter ants dangerous to my home?
Carpenter ants do not eat wood — they excavate it to create galleries for nesting. Over years, a large colony can cause meaningful structural damage to moisture-softened wood. Their presence usually indicates an underlying moisture problem (roof leak, plumbing leak, poor drainage) that should be addressed alongside the ant treatment.
