Mosquitoes
Mosquito action update: 17 February 2021
The City is aware of the continuing increased mosquito activity in the vicinity of the Swan River, in particular Ascot Island and Garvey Park. The main contributing factor to this increased mosquito activity has been a succession of high tides which result in creating extensive breeding habitats for mosquitoes. The standing water that remains after tidal waters subside creates an ideal environment for mosquitoes to lay their eggs.
Treatment to all known breeding sites throughout the City of Belmont is undertaken on a regular basis. Treatment is undertaken using target specific larvicides which prevent mosquito larvae from emerging in to adult mosquitoes. The practice of “fogging” is not target specific and is not undertaken due to the detrimental effects on other forms of wildlife.
Despite continual treatment mosquito breeding is only able to be reduced and not eliminated. The City continues to work proactively with neighbouring Local Governments and the State Health Department as this problem is being experienced across a number of local government areas.

Mosquitoes in the community
Mosquitoes can be a real pest when you are trying to enjoy the great outdoors. Not only can they be a nuisance, they can also transmit debilitating diseases such as Ross River Virus and Barmah Forrest Virus.
Mosquito numbers can vary dramatically from year to year. Temperatures, tides, the amount of rainfall and other factors can have a big impact on mosquito growth cycles.
Partnering for better health
To help reduce the number of mosquitoes in the warmer months, the City of Belmont treats its tidal flood plains and wetlands regularly. The City works closely with neighbouring local governments and the WA Department of Health to coordinate and plan its mosquito management.

How to prevent mosquito breeding around your home and business
Mosquitoes do not only breed in wetlands and the tidal flood plains. Some types of mosquito are able to breed in stormwater drains, gutters, pot plants, tyres and any other container around your home or business that is able to hold water.
To help prevent mosquitoes breeding near you, you can:
- Remove all stagnant water sources such as pot plant bases, blocked gutters and any unused containers;
- Empty pot plant drip trays once a week or fill them with sand;
- If you have a fishpond, keep it stocked with fish;
- If you have a swimming pool, make sure it is kept chlorinated, filtered and clean;
- Empty and clean pet drinking water bowls once a week;
- Ensure septic tanks are sealed and that vent pipes have a mosquito-proof cowl;
- Cover rainwater tank inlets and overflow pipes with flywire.
Protect yourself from mosquitoes
To protect yourself and your family from mosquitoes, you can:
- Keep your door and window flywire in good condition to keep out mosquitoes;
- Cut back any dense foliage and long grass that may harbour mosquitoes;
- Avoid being outdoors at dawn and in the early evening – or use personal insect repellent to protect your skin;
- Wear light-coloured, long loose-fitting clothing when outdoors.
