One visit covering the lot: roof void and subfloor first, because that is where problems start and where a surface spray never reaches, then a band around the perimeter through weep holes, eaves, window frames, the bottom course of brick and where paths meet the slab.
Coastal conditions change how long it holds. Salt air and wind-driven rain strip a residual off exposed western and southern walls faster than they do inland, so the sheltered elevations hold longer than the weather side. On a peninsula house expect three to six months depending on exposure. Same pests back inside that window, so are we. Call +61 3 9003 4456 for a fixed price first.
