Mundoolun sits in the Albert River valley, bounded by the Albert River to the east and the Birnam Range to the west. The name is said to come from a Wangerriburra word for death adder, reflecting the area's deep Aboriginal history before pastoral settlement. William Humphries took up the Mundoolun run in 1842, and by 1847 the Collins family (who had bought part of the property in 1844) held it in full. The Collins family went on to build St John's Church at Mundoolun in 1900-02 from local sandstone and cedar, a heritage-listed building with an adjoining cemetery that still stands today.

That pastoral history left genuinely old timber scattered through the valley, not just the heritage church, but homestead buildings, fence lines and sheds that have stood for a century or more, many of them close to the Albert River or tucked against the Birnam Range. Both of those features add termite pressure: river proximity keeps soil moisture up, and the dense vegetation along the range gives colonies cover and food sources close to the boundary of built-up properties. More recently, a rural-residential subdivision has opened off Mundoolun Road, bringing newer homes into the same valley.

For pest control purposes, Mundoolun is really two populations of buildings in one valley: century-old structures that need careful, respectful inspection, and newer rural-residential homes that need standard but thorough termite protection. We treat them differently rather than running the same script on both.
