The mangrove biting midge, Culicoides ornatus, causes widespread pest problems in mangrove areas along the NT coast. The midges that are found around mangroves only fly in high numbers about 1.6km from mangrove areas. Biting midges do not transmit disease to humans in Australia, but they cause an itchy bite that can sometimes become infected.

The northern salt marsh mosquito, Aedes vigilax, is the most important pest mosquito in the Top End because of its aggressive biting habits during the day and night. It can carry and transmit Ross River virus and Barmah Forest virus disease in the NT. You need to protect yourself to avoid being bitten. The highest risk period for these diseases is from December to March. Get the salt marsh mosquito pest calendar from the Department of Health Research and Publications Online digital repository.
