Argentine ants, odorous house ants, and pavement ants are a year-round nuisance across the Central Valley.
About ants in the Central Valley
Ants are the #1 pest call we receive across Visalia, Fresno, Madera, and Clovis. Argentine ants in particular form massive super-colonies with many queens, which is why a problem in one room of your home is almost always tied to a much larger network of nests outside. Identifying the species correctly is the difference between a one-time fix and a problem that keeps cycling back.
Why it's a problem
Ant colonies can contain thousands of workers and dozens of queens. Store-bought sprays usually make things worse — they kill foragers but trigger the colony to 'bud,' splitting into satellite nests that pop up in walls, electrical boxes, and slab cracks. Beyond the nuisance, ants contaminate food, attract other pests, and some species (like fire ants) bite.
What homeowners can try first
Real tactics that can help with light pressure — and the honest limits of each.
- Wipe down trails with soapy water or vinegar.Limit: Removes the scent trail temporarily, but workers re-mark within hours.
- Seal obvious entry points around door sweeps and weep holes.Limit: Helps, but ants exploit cracks too small to see — full exclusion needs an inspection.
- Use bait stations (gel or granular) instead of sprays.Limit: Baits work, but only if matched to the species — sugar baits fail on protein-feeding colonies.
- Clear vegetation touching the house and fix moisture issues.Limit: Reduces pressure, but established colonies in the soil won't leave on their own.

The professional process for ants
Every pest has a different biology — and a different process. Here's how we handle ants specifically.
- 01
Inspection & species ID
We confirm the species — Argentine, odorous, pavement, or carpenter — because the treatment strategy is completely different for each.
- 02
Non-repellent perimeter treatment
We apply non-repellent products that workers carry back to the colony before they realize anything's wrong.
- 03
Targeted interior baiting
Inside, we use food-matched gel baits placed away from kids, pets, and surfaces.
- 04
Exclusion & follow-up
We seal common entry routes, recommend simple yard adjustments, and follow up to confirm the colony is gone — not just the foragers.
Treatment methods — and what Invictus actually offers
Pest control companies use a wide range of methods, and not every company offers every one. Here's exactly what's standard in the industry, and where Invictus fits in.
- Invictus offers this
Non-repellent perimeter treatment
Modern non-repellent insecticides applied to the foundation, weep holes, and harborage. Workers pick it up and share it through the colony.
- Invictus offers this
Targeted gel & granular baiting
Species-matched baits placed in cracks and known trails. Slow-acting on purpose so workers feed the queen.
- Invictus offers this
Integrated Pest Management (IPM) & exclusion
Sealing entry points, moisture correction, and habitat reduction so the pressure goes down long-term.
- Not a service we perform
Indoor broadcast spraying
Old-school sprays applied across baseboards and counters. Repels rather than eliminates — and often splits the colony.
We avoid this approach. It's what makes most DIY ant problems worse.
- We refer to a specialist
Carpenter ant structural treatment
Drilling and treating active galleries in structural wood.
We diagnose carpenter ant activity and refer to a structural pest specialist when wood-destroying treatment is required.
