Risk Background

The mosquito, Aedes albopictus, is a vector of several exotic indigenous arboviruses affecting both animals and humans.

Tyres that have been contaminated with water may provide a pathway for exotic mosquito larvae and eggs. Even after the water has evaporated, eggs of some mosquito species can remain viable for months. Tyres that contain water or have previously held water (evident through watermarks) must receive a treatment to mitigate all mosquito life stages that may be present (e.g. eggs, larvae, pupae and/or adults).

Tyres with contamination of biosecurity concern may have soil borne diseases or seeds and must be cleaned and treated to remove the biosecurity risk.

A combination of treatments may be required to address the identified risks associated with this commodity.
