Mosquitoes

The NSW Mid-North Coast is home to many species of mosquitoes. As well as being a nuisance, some mosquito species spread human disease causing pathogens such as Dengue fever, Ross River and Barmah Forest viruses, and Murray Valley encephalitis.

Some mosquito species that are capable of spreading these viruses breed in water-filled containers around your home such as buckets, old tyres, roof gutters and pot plant holders. Don’t let your home be a haven for disease spreading mosquitoes.

Council undertakes weekly monitoring of mosquito numbers and species with CO2 light traps between December and April as part of NSW Health’s arboviral surveillance and mosquito monitoring program. The collected mosquitoes are sent to Sydney for counting, species identification and virus detection.

Avoiding Mosquito Bites - NSW Health advice

  • Cover up.
    Minimising the amount of exposed skin to reduce the risk of mosquito bites. Wear loose, light-coloured clothing, long sleeves, pants, socks and shoes. Some mosquitoes will bite through clothing. Consider using clothing pre-treated with insecticides but remember that repellent must still be applied to exposed skin.
  • Apply mosquito repellant.
    Use a mosquito repellent on all exposed skin areas in accordance with the product directions. NSW Health advises the most effective mosquito repellents contain Diethyl Toluamide (DEET) or Picaridin. Repellents containing oil of lemon eucalyptus (OLE) (also known as Extract of Lemon Eucalyptus) or para menthane diol (PMD) also provide adequate protection.
  • Use appropriate insecticides
    Aerosol insecticide sprays, mosquito coils (used outdoors) and insecticide vapour dispensing units (used indoors) can help to clear rooms or areas of mosquitoes or repel mosquitoes from an area. These products should be used in addition to, not in place of, other measures such as appropriate clothing and skin repellents.
  • Avoid peak biting times.
    Take extra care during peak mosquito biting hours to reduce the risk of infection. Avoid the outdoors or take preventive actions (such as appropriate clothing and skin repellent). In NSW, most mosquitoes become active at dawn and dusk, and into the evening.
  • Reduce mosquito risk around the home.
    Stop adult mosquitoes entering the home by using flyscreens on windows and doors, and screening chimneys, vents and other entrances. Repair any damaged screens. Also consider using a surface insecticide spray in areas where mosquitoes like to rest. During the day, mosquitoes rest and hide in cool shady areas such as in and around the home before emerging at dusk to feed.

    Tips for the home.

    • Keep the yard clean removing all water-holding rubbish including tires and containers.
    • Keep the lawns mowed.
    • Flush and wipe out bird baths and water features once a week.
    • Fill pot plant bases with sand to avoid standing water.
    • Store anything that can hold water undercover or in a dry place and keep bins covered.
    • Flush out the leaves of water-holding plants such as bromeliads.
    • Keep drains and roof guttering clear.
    • Cover or securely screen the openings of septic tanks and rainwater tanks.

    Tips for the farm.

    • Keep dams and ground pools free of vegetation.
    • Check dam walls and irrigation bays for water leaks
    • Don't over irrigate to avoid water collecting in low lying areas.
