Pattern Grammar (LTRS): a simple way to log termite clues

LTRS = Location, Timing, Recurrence, Spread. Patterns tell a clearer story than any single clue. This page helps you capture patterns—without scraping or guessing.

Location (L)

• Check seams: slab-to-sill, foundation cracks, siding transitions.
• Interiors: baseboards, window/door frames, plumbing penetrations.
• Attic/crawl: joists, vents, prior repair areas.

Timing (T)

• After warm, humid weather (swarmers drop wings).
• After rain or leaks (moisture changes).
• Night vs daytime HVAC cycles.

Recurrence (R)

• Do tubes or pellets return after gentle cleanup?
• How quickly—hours, days, weeks?
• Note dates/times in your log.

Spread (S)

• Growing length/number of signs?
• New rooms or materials affected?
• Any movement from exterior → interior?

If multiple LTRS factors stack up, a licensed inspection is the next step. We don't identify pests or review photos.
