How to Use This Calculator

Select your Region (southeastern US, Pacific Northwest, etc.) since pest pressure varies significantly by climate.
Enter Home Age — older homes with more gaps and wood deterioration are more susceptible to pest entry.
Toggle Crawl Space and Wood Siding to flag the high-risk construction features that attract termites and ants.
Review Inspections per Year and Annual Cost to budget for a professional pest management agreement.
Check Termite Risk and Pest Pressure outputs to understand whether preventive treatment is warranted.
Use Prevention Budget to plan the annual spending on sealing, baiting, or chemical barriers for your risk level.

What each input means

Region: 0 = Northeast, 1 = Southeast, 2 = Midwest, 3 = Southwest, 4 = Northwest.
Home Age: Age of the home in years. Older homes have more entry points and higher pest vulnerability.
Has Crawl Space: 0 = No (slab foundation), 1 = Yes (crawl space or pier/beam). Crawl spaces increase pest risk.
Has Wood Siding: 0 = No (vinyl, brick, stucco), 1 = Yes. Wood siding attracts termites and carpenter ants.

What each result means

Inspections Per Year: Recommended number of professional pest inspections annually.
Annual Inspection Cost: Estimated yearly cost for professional pest inspections.
Termite Risk: Termite risk score from 1 (low) to 5 (very high) based on region and home factors.
Pest Pressure Code: Overall pest pressure: 0 = Low, 1 = Moderate, 2 = High, 3 = Very High.
Total Prevention Budget: Recommended annual budget for inspections plus preventive treatments.
