Ant Control & Extermination Guide (2026 Treatment Protocols)
Ants are the #1 pest problem reported by U.S. homeowners. Eliminating a colony requires targeting the egg-laying queen rather than killing surface workers.
Colony eradication protocols and non-repellent transfer chemistry conform to research published by UC IPM Extension and the U.S. EPA.
Common Household Ant Species Identification
| Species | Physical Traits | Nesting Sites | Primary Hazard / Food Preference |
|---|---|---|---|
| Carpenter Ant (Camponotus) | Large (1/4 to 1/2 inch), black or reddish-black | Moist structural wood, window sills, hollow doors | Structural timber damage; feeds on sweets & insects |
| Red Imported Fire Ant (Solenopsis invicta) | Small (1/16 to 1/4 inch), dark reddish-brown | Mounded soil in lawns, electrical junction boxes | Painful venomous stings; agricultural & lawn hazard |
| Odorous House Ant (Tapinoma sessile) | Tiny (1/16 to 1/8 inch), dark brown/black | Wall voids, under carpets, beneath rocks | Emits rotten coconut odor when crushed; sugar preference |
3-Phase Ant Colony Extermination Protocol
- 1. Non-Repellent Liquid Perimeter Barrier (Taurus SC / Termidor): Applied to exterior foundation walls. Foraging ants walk across active ingredient without detecting it, transferring chemistry back to nest mates and the queen.
- 2. Slow-Acting Granular & Gel Baiting: Placing carbohydrate- and protein-based gel matrixes along active trailing paths. Workers carry toxicant directly to queen larvae.
- 3. Moisture Reduction & Vegetation Clearance: Trimming tree branches touching rooflines and caulking utility pipe penetrations.

Frequently Asked Questions
Over-the-counter contact sprays contain synthetic pyrethroids that act as repellents. Sprayed ants trigger a budding response, causing the colony to split into multiple satellite queens and spreading the infestation deeper into wall cavities.
Unlike termites which eat wood cellulose, Carpenter ants excavate smooth galleries inside damp structural wood to nest, weakening support beams and framing over time.
