Territorians are being warned to be cautious about disease carrying mosquitoes during the upcoming peak breeding period from October to January, with adult mosquitos expected to be flying from Friday as part of an anticipated spike in numbers this year.

The current high tide is expected to trigger extensive salt marsh mosquito breeding this week, NT Health said, adding salt marsh mosquitos are “aggressive biters” that can transmit diseases such as Ross River virus and the Barmah Forest virus disease.

NT Health said it has been actively surveying to detect mosquitoes and recently carried out “control operations” in the urban areas of Darwin and in the wetlands surrounding the northern suburbs between October 9 and 13.

To minimise the chance of being bitten by mosquitoes, individuals should take several precautions, such as wearing protective, light-coloured clothing, including long sleeves and long trousers, along with ankle protection, like socks, especially in areas where mosquito bites are likely.

Using a protective repellent that contains DEET, picaridin, or oil of lemon eucalyptus (OLE) can enhance protection when outdoors in regions with active mosquito populations.

It is also advisable to avoid exposure to coastal swamps and mangrove areas, as these locations are often breeding grounds for mosquitoes. Furthermore, utilising mosquito coils, lanterns, and barrier sprays in outdoor areas and near homes can help prevent mosquitoes from entering living spaces.

NT Health said it is also vital to ensure that infants, children, and animals are adequately protected from mosquito bites.

The NT hosts over 100 species of mosquitoes, some of which can carry diseases that affect humans, pets, and livestock.

Among the illnesses transmitted by mosquitoes are the Ross River virus, which may lead to symptoms such as fatigue and muscle pain, as well as more severe diseases, including Murray Valley encephalitis and Japanese encephalitis virus, both of which can pose life-threatening risks.
