Flies and midges

There are different types of flies found in Western Australia, and many of them never bother us – in fact, many species of flies are useful for pollination and disposal of manure.

The flies that do pester us can be annoying and, in some cases, dangerous to our health by and damaging to important industries.

Preventing fly breeding

You can prevent flies breeding in and around your home by taking some basic steps:

• Make sure your rubbish and recycling bins are clean and closed at all times.
• Wrap all food scraps tightly and place them in the bin immediately.
• Keep poultry and pet areas clean at all times.
• Don't leave lawn clippings in heaps, rake them out thinly.
• Dig any manures and fertilisers well into the soil.

Fruit fly

The fruit fly or medfly is a serious horticultural pest in Western Australia, damaging crops and reducing income for our growers and farmers.

Under the Biosecurity and Agriculture Management Act 2007, fruit fly is a declared pest and is mandatory to control in some areas of WA, including Armadale, Kalamunda, Mundaring, Serpentine-Jarrahdale and Swan.  

In Bassendean, our proximity to the Swan Valley means we have a special responsibility to prevent the spread of fruit fly to businesses in the area.

Backyard growers should dispose of fly-infested or unwanted fruit, including fruit left on the tree.

Find out more about controlling fruit fly on the Department of Primary Industries and Regional Development’s website. 

Midges

Midges are small, gnat-like flies often found near wetlands.

Non-biting midges don’t carry disease but can cause a nuisance in residential areas.

Midges can swarm in large numbers. However, these mating swarms are usually short-lived and tend to disperse within a few days.

As midges do not carry disease, Health Services do not treat for them.
