Asian Tiger Mosquito

Preventing Asian tiger mosquito establishment on the mainland relies on both national biosecurity controls and property-level habitat removal. At the border, imported used tyres — a well-documented pathway for this species worldwide — require certified methyl bromide fumigation before shipment, and cargo moving between the Torres Strait and the mainland is inspected under the government's ongoing containment program, described by CSIRO. Around the home, the priority is eliminating stagnant water where larvae develop: empty and scrub plant saucers, bird baths, buckets and other small containers weekly, since Aedes albopictus eggs resist drying and can hatch once water returns. Cover water storage containers with insect-proof mesh, clear gutters and downpipes of leaf litter, and either empty neglected ornamental ponds and pools or treat them with larvicide. This mirrors the source-reduction work that underpinned Australia's Torres Strait containment program, which combined household inspections with insecticide treatment of containers that could not be emptied. Any suspected daytime-biting, black-and-white striped mosquito found outside the Torres Strait should be reported to the relevant state health department immediately, since Aedes albopictus can transmit dengue and other arboviruses and climate modelling shows most of the north, east and south-east coasts as far south as Victoria are suitable for it to establish, as reported by the Australian Government Department of Health.
