Mosquito Control

Spring/Summer 2020-2021

Spring is when people start to notice mosquitoes have become active again, and this year’s wet spring will provide for ideal mosquito breeding conditions.

This does not mean there is a cause for concern, but it pays to remain vigilant.

Mosquitoes can never be entirely eradicated, and while the City of Salisbury is committed to checking and treating common breeding grounds on public land, different species breed in different areas and all sorts of water bodies so it is important that you protect yourself from mosquitoes by covering up, using repellent and eliminating local breeding.

This year’s climate outlook and increased rainfall will have a direct impact on a range of areas including the level of mosquito activity. During spring and summer we expect to see an increased level of mosquito activity across all of City of Salisbury’s suburbs, especially those in close proximity to the coastal environments, brackish water catchments and local stormwater catchments.

Quick facts

  • Mosquitoes breed in calm water. One small pool of water may produce thousands of mosquitoes each week.
  • Only female mosquitoes bite. They bite to get your blood to be able to produce eggs and breed.
  • Mosquitoes can carry disease such as Ross River Virus.

Are you breeding your own mosquitoes?

What can we as a community do to control mosquitoes and stop them breeding? You can start in your own backyard by recognising and controlling breeding sites.

  • Throw away any unwanted containers which hold water (eg- old tyres, drums, pot plant bases etc).
  • Seal or cover all openings in rainwater tanks to stop mosquitoes from getting in.
  • Make sure roof gutters are not holding water. Clean gutters out regularly.
  • Continuously filter and chlorinate swimming pool water. Unchlorinated pools allow breeding.
  • Empty pot plant drip trays once a week or fill with sand.

Self protection

  • Check that fly screens around the home are fitted appropriately and do not have large holes.
  • Avoid outdoor activities at dawn and dusk when mosquitoes are most active.
  • When you are outside and mosquitoes are present, wear light coloured, loose long sleeved shirts and long, loose pants and apply an insect repellent.
  • A tropical strength insect repellent is the most effective protection for uncovered skin. Tropical strength repellents contain a chemical barrier which blocks the sensors of mosquitoes. Always follow the manufacturer's instructions when using any type of insect repellent.
  • Mosquito coils and citronella candles are also effective for discouraging unwelcome mosquito visitors at BBQ's or other outdoor activities.

Mosquito Management

The City of Salisbury recognises that undertaking a mosquito control program including the surveillance and control of mosquitoes, is a key strategy to manage and minimise the public health effects and nuisance issues associated with mosquitoes. The steps and acitons carried out by the City of Salisbury can be found in the City of Salisbury's Mosquito Management Plan.

City of Salisbury's Mosquito Management Plan

Mosquito control is focussed on the coastal environments of St Kilda and Globe Derby Park and adjancetn suburbs where mosquito activity can be high. St Kilda and Globe Derby Park in particular are adjacent to an extensive region of both mangrove and samphire swamps. This area provides an important environmental habitat, however also provides for significant mosquito breeding activity. The habitats for mosquitoes include a number of samphire swamp and intertidal zones which provide pools of water suited to mosquito breeding. In addition, Globe Derby Park is a low lying area and environmental factors provide ideal breeding grounds for mosquitoes.

Council's ongoing commitment to the management of mosquitoes includes the treatment of known breeding sites as well as monitoring adult mosquito numbers and environmental factors (eg rainfall) in order to best address the concern. In addition the mangrove and samphire swamp areas to the west of Globe Derby include private and Crown Land that are treated by SA Health as part of their annual mosquito control program.
