How Often Should You Treat For Termites
Track termite inspections, evidence and warranty dates without inventing an automatic pesticide reapplication interval. Inputs stay in your browser.
The planner schedules professional inspection and contract checkpoints. It never turns treatment age into an automatic pesticide application date; evidence, barrier condition and the exact EPA-approved label control retreatment. Review note: Professional inspection checkpoint reached.
Context matters.
- EPA termiticide labeling says retreatment for subterranean termites is allowed only with clear reinfestation, barrier disruption or evidence of barrier breakdown; annual retreatment is prohibited without that evidence.
- EPA's minimum efficacy policy and five-year warranty context do not create a universal five-year reapplication date. Product, termite pressure, soil and site conditions vary.
- Do not use this page to choose a pesticide, dilution, dose or application method. Follow the current label, state requirements and a licensed pest-management professional.
Sources & scope
The calculation guide and this source trail show what the result means, where the rule came from and when it was last reviewed. This is source-and-calculation QA, not a claim of medical, legal, tax or other professional review; time-sensitive decisions still belong with the linked authority.
A visible path from input to answer.
Track termite inspections, evidence and warranty dates without inventing an automatic pesticide reapplication interval. The page keeps the calculation scope and its limits beside the result so the output can be checked, copied or revisited.
- Read the record. The calculator uses Last termite treatment / installation, Check date, Last professional termite inspection, Treatment system on the record and Inspection interval from contract / professional plan (months) and 5 additional fields supplied in the form.
- Apply the scope. It applies the United States — EPA termiticide labeling; exact product label, state law and licensed inspection control reference and the explicit date, unit and counting conventions shown in the result.
- Expose the checkpoints. Intermediate rows, warnings and timeline events stay visible; the emphasized row identifies the primary checkpoint when one exists.

Calculation purpose: Track termite inspections, evidence and warranty dates without inventing an automatic pesticide reapplication interval. This is a conditional reference output; the linked source and the situation-specific facts control the decision.
Calendar inputs use plain year-month-day semantics. Leap days, month ends, date-pair order and unsupported dates are checked before the result is shown.

What to know before using the result.
Should a termite barrier be reapplied every year?
No. EPA termiticide labeling says annual retreatment is prohibited unless there is clear evidence of reinfestation or barrier disruption. Inspection and the exact label control the decision.
Does a five-year efficacy reference create a five-year retreatment date?
No. EPA uses efficacy evidence in product registration, but retreatment timing still varies by product, termite pressure, soil, barrier condition and evidence. CalcSpan therefore creates inspection and warranty checkpoints, not an automatic application date.
What should I do if I see live termites or new tubes?
Arrange prompt identification and inspection by a licensed pest-management professional. Do not use the calculator to select a pesticide, dose or application method.
