What to know

A permittee who treats for subterranean termites signs a written contract guaranteeing retreatment if the pest returns within one year; it transfers to a later owner and is copied within thirty days of a written request. Each contract covers one unit, guarantees at least one year with an inspection before it expires, includes inspection diagrams, covers termites, powder post beetles and old house borers, and adds an approved addendum for monitoring stations; spot treatments guarantee the treated area a year, and contracts (or a no-contract report) are due by the tenth of each month. Know supplemental versus spot treatment, new-construction treatment up to 12 months after completion, hydraulic injection and subterranean termite traits. WDIRs are only for sale or refinance, come from termite licensees or certified WDIR technicians, carry a 90-day free-treatment guarantee and can't extend treatment time in comments. Records are kept three years and shown within 48 hours. Vehicles carry spill kits and the business name in 2-inch letters, and tank hoses need an air gap or backflow preventer. Termite work uses commission-approved products, trenches at least six inches deep, volume figured on one foot of depth, slab holes no more than 18 inches apart, one-hour pre-treat notice, a poster on unfinished pre-treats and perimeter treatment within 12 months. Fumigation needs 24-hour written notice, POISON signs, two trained people at release and full-building evacuation. Store containers securely, dispose within 90 days, reuse rinsate and report spills over 1 gallon within 24 hours.
