#### Formulas Used

Adjusted Cost Per Visit:

Adjusted Cost = Base Cost × Size Multiplier × Property Type Multiplier × Location Multiplier × Contract Discount

Size Multiplier:

Size Multiplier = (Property Size ÷ 1,500)0.6

The exponent 0.6 reflects economies of scale — larger properties cost more but not proportionally.

Annual Maintenance Cost:

Annual Cost = Adjusted Cost Per Visit × Recommended Visits Per Year

Initial Treatment Cost (active infestations only):

Initial Cost = Base Cost × Size Multiplier × Property Multiplier × Location Multiplier × Severity Factor Severity Factors: Low = 1.5×, Moderate = 2.0×, Severe = 3.0×

Total First-Year Cost:

Total First Year = Initial Treatment Cost + Annual Maintenance Cost

#### Assumptions & References

Base costs per visit are national U.S. averages sourced from HomeAdvisor / Angi (2023–2024): General insects ~$120, Termites ~$575, Rodents ~$200, Bed Bugs ~$400, Mosquitoes ~$150, Wildlife ~$350.
The 1,500 sq ft baseline represents the U.S. median single-family home size used by most pest control pricing guides.
The power-law size scaling (exponent 0.6) reflects industry practice where larger properties receive volume discounts but still cost more overall.
Visit frequency recommendations align with National Pest Management Association (NPMA) guidelines and EPA Integrated Pest Management (IPM) principles.
Annual contract discount of 15% is a typical industry average; actual discounts range from 10–25% depending on provider.
Commercial properties are estimated at 1.4× residential rates due to regulatory compliance, larger treatment areas, and liability considerations.
Rural locations receive a 10% discount reflecting lower labor/travel overhead in less dense areas; urban areas carry a 10% premium.
All costs are in USD and represent estimates only. Actual quotes will vary by region, provider, and specific conditions.
