Mosquitoes: A Common Pest in Ballina Shire
Australia is home to over 300 mosquito species, but only a few are problematic. In Ballina Shire, these pests cause more than a mere nuisance; they pose health risks by spreading diseases like Ross River fever and Barmah Forest virus.
Mosquito-Borne Diseases: Understanding the Risk
In Ballina Shire, the two prevalent mosquito-borne illnesses are Ross River fever and Barmah Forest virus. These infections, while not life-threatening, can lead to symptoms such as joint pain, fatigue, fever, and rash. These symptoms can persist for days to months. Thankfully, dengue and malaria are not transmitted by Ballina Shire’s mosquito population.
To learn more about these diseases, visit the NSW Health website for Ross River fever and Barmah Forest virus.
Why Do Mosquitoes Bite?
Interestingly, it’s only female mosquitoes that bite humans and other mammals. This is because they need the protein found in human blood to produce eggs. Other sources of blood for these insects include native animals like wallabies, birds, and cats.
When mosquitoes bite, they can transmit disease-causing viruses and parasites. Exposure to high mosquito populations increases the risk of mosquito-borne infections.
Ross River Fever and Barmah Forest Virus: Similar, But Not the Same
Ross River fever and Barmah Forest virus are infections transmitted through mosquito bites. These diseases are widespread in Australian regions with warm, humid climates and proximity to bodies of water, where mosquitoes breed.
The symptoms of both diseases are almost identical—rashes, fatigue, and muscle aches. Unfortunately, there are no specific treatments available, but proper rest, hydration, and a healthy diet can help speed up the recovery process.
Why Do Mosquitoes Seem to Target Some People More Than Others?
Several factors can make some people more attractive to mosquitoes. Over 400 chemical compounds on human skin may play a role in attracting mosquitoes. These compounds can include carbon dioxide, lactic acid, and certain body odors.

How to Protect Yourself from Mosquito Bites
- When outdoors, cover as much skin as possible with loose, light-colored clothing and closed-toe footwear.
- Avoid outdoor activities during peak mosquito hours, dusk and dawn.
- Use insect repellents containing DEET, picaridin, or oil of lemon eucalyptus. Apply them evenly over all exposed skin.
- Indoors, use mosquito coils or vapor mats to keep mosquitoes at bay. Mosquito traps are not effective in reducing the mosquito population.
- Install insect screens on all windows and doors to prevent mosquitoes from entering your home.
Minimizing Mosquito Populations in Your Home
- Install insect screens on windows and doors.
- Regularly mow your lawn to keep vegetation under control.
- Empty bird baths, pet bowls, and water features weekly.
- Dispose of and clean pot plant bases regularly.
- Eliminate any containers that can hold water.
- Clear gutters of leaves and debris to ensure proper drainage.
- Keep swimming pools chlorinated, and operate the pump year-round.
- Screen access to water containers like wells and tanks.
- Stock fishponds with native fish that feed on mosquito eggs.
Ballina Shire Council’s Mosquito Control Efforts
While Ballina Shire Council does not implement mosquito spray programs, their Environmental Health Officers monitor mosquito populations and gather data for NSW Health to assist in minimizing the risk of mosquito-borne diseases.
The monitoring program includes trapping mosquitoes in various locations within Ballina Shire. The trapped mosquitoes are identified and counted at Westmead Hospital, and any arboviruses are isolated. For more details on the program, visit NSW Health’s Mosquito-borne Disease Surveillance.
Council also works with consultants, entomologists, and landscape architects to design new developments that minimize residents’ exposure to mosquitoes. This includes establishing buffer zones between mosquito habitats and developments and designing water holding devices to prevent mosquito breeding.

Understanding Biting Midges in Ballina Shire
Biting midges, also known as sandflies, are small insects belonging to the family Ceratopogonidae. Some species can pierce human skin and drink blood, causing a nuisance in coastal environments. However, these pests are not known to transmit human diseases.
- Biting midges are most active at dawn and dusk, in areas with minimal air movement, and shelter among vegetation.
- Females bite humans while males feed on nectar.
- They lay eggs on mud, moist soil, decaying vegetation, and other organic substrates.
- A biting midge can grow up to 4mm long, and its life cycle ranges from 3 to 10 weeks.
Biting midge bites cause acute discomfort, often leading to inflammation, redness, and itching. In some cases, the irritation can cause bacterial infections or allergic reactions requiring medical attention.
Preventing Biting Midge Bites
- Plan outdoor activities during the middle of the day, away from dawn and dusk.
- Cover exposed skin and use insect repellents containing DEET or picaridin.
- Minimize vegetation around your home to improve air circulation.
- Install fly screens with smaller mesh to keep biting midges out.
- Use mosquito coils or vaporizers indoors.
Environmental Impact of Biting Midge Control Methods
Biting midges breed in ecologically sensitive areas, making it challenging to control them without harming the environment. No approved larvicides or pesticides are available specifically for biting midges.
Ballina Shire Council does not conduct a biting midge control program due to potential harm to the ecosystem, particularly native fish species.
