Ground treatment: if breeding sites are easily accessible, ground crews can treat the area manually. Breeding sites around townships like pits and drains are always treated by ground based methods.
Aerial treatment: we have a permit from the Commonwealth Government (EPBC 2005/2132) that allows aerial treatments for mosquito larvae to take place in RAMSAR protected wetlands on the Bellarine Peninsula between 15 August and 15 March each year.
This involves dropping pellets from a helicopter into remote water bodies. Treating mosquito breeding sites by aerial methods is effective in reaching areas that are difficult to access.
Aerial treatments only take place in the wetlands, they do not occur over townships.
