2–10 million workers. 13 oz of wood per day. Builds above-ground carton nests inside walls — does not need soil contact once established. Requires dual-front operation: remove carton AND treat ground colony.
Live in the soil, forage upward. Require soil contact for moisture — the trench-and-barrier treatment severs their access. Termidor SC non-repellent transfer effect eliminates the colony over 5–6 weeks.
Live entirely inside the wood they eat. Enter through exposed joints, gaps in fascia, and attic vents. Smaller colonies (thousands, not millions) but extremely difficult to reach without foam injection or fumigation.
This contract gives you the exact protocol professional pest controllers use — household items when they work, professional-grade chemicals when they don't.
Formosans build carton nests inside walls — compressed wood pulp, soil, and feces that retain their own moisture. Chemical treatment alone won't eliminate a colony with an active carton. You must physically remove it first.
Scan all walls with a moisture meter. Readings above 20% with no plumbing explanation = suspected carton. Mark every location. Tap walls — carton-packed voids sound different than empty ones.
Cut drywall at marked locations. N95 respirator required — carton dust carries mold and frass. Remove the entire carton into sealed trash bags. Dispose immediately. Leave zero remnant material — they rebuild inside what's left.
Inject Termidor Foam into all mud tubes and drill holes 4" apart into damaged wood — inject 5 seconds per hole or until foam exits. Do not remove damaged wood yet. Let foam work 5–6 weeks.
Trench 6"×6" around full perimeter. Mix 3.2 oz Taurus SC per 4 gal water per 10 linear feet. Apply and backfill. Trench and treat separately around every pier and block in crawl spaces.
