Within Australia there are more than 300 different species of mosquito but only a small number cause nuisance biting problems or spread disease-causing pathogens.
The two most common mosquito-borne diseases in our local area are Ross River Virus and Barmah Forest Virus. These diseases are not fatal but can cause symptoms including joint pain, muscle tiredness, fatigue, fever, and rash that may last from days to months. Mosquitoes within Ballina Shire do not transmit dengue or malaria.
Only the female mosquito will bite humans. The female mosquito needs the protein in a blood meal to help develop their eggs. Mammals including wallabies, birds, dogs, cats, snakes, and other native wildlife are other blood sources. While taking blood they can pass on disease-causing viruses and parasites. Exposure to large numbers of mosquitoes may increase the chance of being infected with a mosquito-borne disease.
Ross River virus and Barmah Forest virus are infections that are spread to humans through mosquito bites. Mosquitoes are not “born” infected with either virus, they must acquire the viruses from an infected animal. The viruses occur throughout most regions of Australia. Human infections tend to occur more often in regions with a warm, humid climate that are close to bodies of water where mosquitoes breed.
Ross River virus and Barmah Forest virus have the same symptoms including fatigue, rashes and muscle aches and pains. There is no specific treatment; however plenty of rest, moderate exercise and healthy eating may help reduce the recovery time.
There are over 400 chemical compounds on human skin that could play a role in attracting mosquitoes.
There's always one in a crowd, a person mosquitoes seem to target more than others. What is it about these unlucky few that make them so attractive to mosquitoes? Or is it the reaction people experience which make them think they are being targeted by mosquitoes? Visit the Conversation website - why mosquitoes seem to bite some people more
Council’s Environmental Health Officers are actively involved in mosquito monitoring during the warmer months and data collected is provided to NSW Health to assist in minimising mosquito borne risk.
The program involves the trapping of mosquitoes at a number of sites within the Ballina Shire. The mosquitoes are then sent to Westmead Hospital where they are identified, counted and species identified with arboviruses (Arthropod-borne viruses) isolated from mosquitoes when present. Results of the trapping and further information on the program is available on the The Arbovirus website - NSW Arbovirus Surveillance & Mosquito Monitoring Program.
Additionally, Council work with planning consultants, entomologists and landscape architects to ensure new development is designed to minimise the exposure of residents to mosquitoes. Council’s Development Control Plan has controls for new developments to help minimise the impacts of mosquitoes. This includes things like:
This issue is also considered at rezoning stage.
Council continues to engage experts to review the provisions in Council’s Development Control Plan so they can be improved to further minimise mosquito impacts. These reviews inform Council of best practice and leading science to minimise nuisance and public health risks associated with mosquitoes.
Biting midges, commonly known as sandflies, are small insects that belong to the family of flies Ceratopogonidae. Some species of biting midge are known to suck blood from humans and animals. Biting midges can cause a nuisance in coastal lagoon environments, estuaries, mangrove swamps, canals and tidal plains but they are not known to transmit diseases to humans.
Biting midges can cause acute discomfort and irritation due to their feeding technique but are not known to transmit any diseases to humans.
Each bite can leave inflammation on the skin which fills with damaged skin tissue and anticoagulants (transferred in the biting midge’s saliva). These bites can trigger an allergic reaction in sensitive people.
General symptoms of the bite sites are swelling, redness, itching and severe irritation (severe irritation can lead to bacterial infection). Acute allergic reactions may require medical attention. Some local residents will build up immunity to biting midge bites over a period of time.
These insects play an important part in the ecosystem being a food source to native fish species. They can be a public health nuisance when housing developments are located close to biting midge breeding environments.
Biting midge life cycles start in environmentally sensitive ecosystems, using larvicide and pesticides can be harmful to the ecosystem, including native fish species. Biting midge larvae exist in substrates such as mud, moist soil, and other organic environments making it difficult to treat them. There are no approved larvicides for the control of biting midges.
Ballina Shire Council does not undertake a biting midge control program due to these reasons.
