Termite Treatment Coverage Area Calculator
Calculate the total coverage area required for termite treatment based on your property dimensions, treatment method, and structure type. Results include perimeter linear footage, soil treatment volume, and estimated product quantities.
Formulas Used
Perimeter: P = 2 × (Length + Width)
Footprint Area: A = Length × Width
Liquid Barrier — Trench Volume (cu ft):
Vtrench = P × 0.5 ft × (Foundation Depth ÷ 12)
Liquid Barrier — Perimeter Gallons:
Gperim = (P ÷ 10) × 4 gal × (Foundation Depth ÷ 12)
Rate: 4 gallons per 10 linear feet per foot of depth (standard label rate)
Liquid Barrier — Sub-Slab / Crawlspace Gallons:
Gsub = A ÷ 10 (1 gallon per 10 sq ft)
Total Liquid Required:
Gtotal = Gperim + Gsub + Ginterior walls
Bait Stations:
N = ⌈P ÷ 10⌉ + ⌈Interior Walls ÷ 10⌉ (minimum 10 stations)
Foam Injection:
Foz = (P + Interior Walls) × 2 oz/lin ft
Assumptions & References
- Liquid barrier application rate of 4 gallons per 10 linear feet per foot of depth is based on standard termiticide label directions (e.g., Termidor SC, Premise 75) per the National Pest Management Association (NPMA) guidelines.
- Trench dimensions of 6 inches wide are per standard industry practice for soil barrier treatments.
- Sub-slab rod injection rate of 1 gallon per 10 sq ft follows EPA-registered product label recommendations for slab and crawlspace structures.
- Bait station spacing of one station per 10 linear feet is per Sentricon® and Advance® Termite Bait System installation guidelines; minimum 10 stations per structure.
- Foam injection rate of 2 oz per linear foot is a conservative estimate based on typical professional application; actual usage depends on void size and foam expansion ratio (typically 30:1).
- Results are estimates only. Always consult a licensed pest control professional and follow all EPA-registered product label instructions and local regulations.
