Do not panic. Termites work slowly; the structure will not be extensively damaged or collapse overnight. Based on normal feeding activity it takes 3 to 8 years to cause appreciable damage.
Take your time to make a sound decision. Do not let anyone force a quick decision. Ask for the plan of work showing where termites are active and how they will be treated, and for written information on chemical treatment, repair of woodwork, warranties, copies of insecticide labels and other pertinent information.
Checking for yourself: probe wood with a screwdriver, ice pick or knife, starting in the basement or crawl space with a bright flashlight. Mud tubes are solid evidence of termite activity. Also check sills, joists, support posts, wood under porches, cracks in block or brick, and scrap wood, stumps and fence posts near the house.
Beware of:
- a "secret formula" only one company has: generally all companies have access to the same chemicals, and the big difference is in the service
- pest control operators with no business address and no listed phone number
- operators with no liability insurance
