How Often Should You Treat For Termites
without the guesswork.
Termite Pest Treatment Reapplication Interval — Track termite inspections, evidence and warranty dates without inventing an automatic pesticide reapplication interval. Includes a practical guide and embedded calculator. 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.
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.

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.
