Conducive conditions
Site or building conditions that attract or sustain timber pests. Things like timber-to-ground contact, blocked vents, dampness, dense vegetation.
Termites need moisture and timber. Conducive conditions are anything on your property that provides both: timber sleepers in garden beds against the house, leaking taps near footings, decking with poor air gap, sub-floor ventilation blocked by raised garden beds, mulch piled against external walls.
Reducing conducive conditions is the cheapest and most effective form of termite prevention. Often free if it's just moving garden beds back from walls, clearing sub-floor vents, or fixing leaking taps.
Inspectors will list conducive conditions in the AS 4349.3 timber pest report, even when no active termites are found. They're the early warning system.
Coptotermes acinaciformis
The dominant subterranean termite species in metropolitan Adelaide. Highly destructive, builds large underground colonies.
Sub-floor ventilation
Air circulation under timber-framed floors. Inadequate ventilation causes timber decay, fungal growth, and termite-friendly conditions.
