There are two main types of midges:
- Biting midge (Sandflies)
- Non-biting midge (chironomids)
Biting Midge
Biting midge are attracted to human habitation and rest on screens, fences and vegetation while waiting to take a blood meal. As the biting midge is small and easily blown about by prevailing winds, they prefer dull still days with high humidity.
The biting midges present in the Fraser Coast region are particularly active during the warmer months, September through to April each year. Midges are very active during dawn and dusk.
The impact on human health and well-being is caused by allergens in the midge saliva which reacts on people with varying degrees of sensitivity and immunity.
What can I do?
There is more work and research to be undertaken in this area, however the following steps may assist in reducing your exposure to biting midge:
- Wear light coloured protective clothing when outdoors during midge activity period (usually early morning and late afternoon)
- Use insect repellents when outdoors
- Midges can enter through normal fly screens so install screens with a smaller mesh sizes to decrease their entry
- Mosquito coils or plug in insecticide tablet burners may be effective to deter biting midges
Non-biting midge
Non-biting midge are often a nuisance in residential areas near wetlands because they are strongly attracted to lights. They do not bite and as such, are not vectors of disease.
During summer, the insects seek cool shady places during the day and can leave behind stains on light-coloured surfaces. They can also clog vehicle radiators, headlights, and air-conditioning units.
Residents can reduce the effect of non-biting midge in the following ways:
- Use dark colours for outdoor surfaces
- Where possible, screen off light sources
