How to Use This Calculator
- Enter the total foundation footprint area in square feet.
- Set the slab type: monolithic, post-tension, or stem wall with crawl space.
- Input the local termite pressure level (low, moderate, high, very high) per NPCA map.
- Review the Termiticide Volume Required and the Coverage Rate per 10 linear feet.
- Use the Post-Treatment Inspection Interval to schedule the first verification visit.
How the result changes with Foundation area (ft²)
| Foundation area (ft²) | Total solution (gallons) | Concentrate needed (fl oz) | Total treatment cost ($) |
|---|---|---|---|
| 5,090 | 562 | 449.9 | $2,355.27 |
| 17,565 | 1,810 | 1,447.9 | $7,170.62 |
| 32,535 | 3,307 | 2,645.5 | $12,949.04 |
| 45,010 | 4,554 | 3,643.5 | $17,764.39 |
What each input means
- Foundation area (ft²)
- Total slab/foundation footprint area.
- Foundation perimeter (ft)
- Total linear feet of foundation perimeter for trench treatment.
- Slab thickness (inches)
- Concrete slab thickness. Determines trench depth for vertical barrier.
- Product (0=Termidor, 1=Premise, 2=Altriset)
- 0 = Termidor SC (fipronil), 1 = Premise 75 (imidacloprid), 2 = Altriset (chlorantraniliprole).
- Soil type (0=Sand, 1=Loam, 2=Clay)
- Sandy soil needs more solution (less retention). Clay needs less.
- Method (0=Horizontal, 1=Horiz+Vertical)
- 0 = Under-slab horizontal only. 1 = Horizontal + perimeter trench (recommended).
What each result means
- Total solution (gallons)
- Total diluted termiticide solution needed.
- Horizontal application (gal)
- Solution for under-slab horizontal treatment.
- Vertical trench (gal)
- Solution for perimeter trench treatment.
- Concentrate needed (fl oz)
- Fluid ounces of concentrated termiticide product.
- Chemical cost ($)
- Cost of termiticide concentrate.
- Labor hours
- Estimated technician hours.
- Labor cost ($)
- Labor at $65/hour.
- Total treatment cost ($)
- Chemical + labor + equipment cost.
- Cost per ft² ($)
- Total cost per square foot of foundation.
How this is calculated
Worked example, using the default values
- Identify Input Parameters4 parametersFoundation area (ft²) = 1500, Foundation perimeter (ft) = 160, Slab thickness (inches) = 4, Product (0=Termidor, 1=Premise, 2=Altriset) = 0 = 6 input(s) provided
- Calculate Total solutionTotal solution = horizontalGallons + verticalGallons203 = 203
- Calculate Concentrate neededConcentrate needed = totalDilutedGallons * product.ratePerGal162.7 = 162.7
- Calculate Total treatment costTotal treatment cost = concentrateCost + laborCost + equipmentCost969.53 = $969.53
