Fighting Mosquito-Borne Diseases

Mosquitoes are more than a summer nuisance in Melbourne. Reducing mosquito numbers around your home is one of the most effective ways to lower your risk of the diseases they can carry.

Which mosquito-borne diseases occur in Victoria?

The Victorian Department of Health reports that Ross River virus and Barmah Forest virus are the most common viruses mosquitoes transmit to humans in Victoria. Japanese encephalitis, Murray Valley encephalitis and West Nile/Kunjin virus are rare here but can cause severe disease.

There is no vaccine for most of these, which is why avoiding bites and reducing mosquito numbers is the practical defence.

Where do mosquitoes breed around your home?

Mosquitoes need still water to lay eggs, and very little of it. A clogged gutter, plant saucer, old tyre or blocked drain can become a breeding site within a week.

• Empty pot plant saucers, buckets and anything collecting rainwater weekly
• Keep gutters clear so water does not pool
• Screen rainwater tanks and downpipes
• Maintain pool and spa chlorine levels, and cover them when not in use
• Trim long grass and dense vegetation where adult mosquitoes rest by day

How else can you avoid mosquito bites?

Better Health Channel advises wearing long, loose-fitting, light-coloured clothing and using a repellent containing picaridin or DEET on all exposed skin. Like sunscreen, repellent only works where it is actually applied.

When should you get professional mosquito treatment?

If your property backs onto a creek, wetland or has persistent damp areas that are hard to eliminate, home measures alone often will not hold mosquito numbers down. Targeted treatment of resting and breeding sites is the next step.
