What to do first is usually straightforward. If you have drywood termites, the infestation is usually limited (sometimes to a single piece of furniture, sometimes to the whole house). For subterranean termites, management should first aim to either exclude the termites (such as by repairing a physical barrier) or kill off the offending colony. Colonies can most often be killed by nest destruction, nest poisoning, by baiting or by judicial use of a non-repellent termiticide into the soil where they are active. Repellent soil poisons are best (not used, or) saved for new construction when you can be sure of a complete barrier. In the ideal world, your pest management technician will do a full timber pest inspection of the building and grounds and present you with a written report and (separately) a management plan (hopefully with a range of options). Again, ideally, remedial soil poison barriers would not be used (i) unless necessary and (ii) until the offending colony had been controlled. Repairs (unless for safety) should not be made until the colony is controlled as early disturbance can make management difficult by breaking up or concealing the termite activity. If baiting or usin a non-repellent termiticide for colony control, you want to keep them feeding at full tilt until they have consumed enough poison to kill the whole colony. . . .
