Will termites go away on their own?

No, termites will not go away on their own and will continue to feed on wood and expand their colonies if left untreated, causing increasing structural damage over months and years that can become very expensive to repair. Subterranean termites live in large underground colonies that can contain several million members and have a queen that can live for many years producing thousands of eggs, so they have no reason to leave as long as there is wood, moisture, and warmth, which most homes provide. Unlike some seasonal pests like wasps that die in winter, subterranean termites remain active year-round in heated homes and in warm climates, and even in cold climates they retreat deeper underground in winter and return in spring to continue feeding. Drywood termites live entirely inside the wood they infest and will remain until the wood is consumed or treated. Termites do not have natural predators inside homes that would eliminate them, and they are protected from drying out by mud tubes. If you ignore termites, they will not disappear but will cause progressive damage including hollowing out studs, floor joists, and support beams from the inside out, leading to sagging floors, hollow-sounding walls, and potential structural failure after 3 to 8 years of active feeding. The only way to make termites go away is active treatment including professional liquid termiticide barriers, bait systems costing $1,000 to $3,000, fixing moisture issues, removing wood-to-soil contact, and ongoing monitoring. So termites require intervention and will not go away on their own.
