Mosquito coils and most insect repellants are effective a�ainst mid�es. Biting midges You can take a big step towards living with midges by making sure you are protected. Biting midges, often referred to as midges, prefer humid overcast conditions with minimal air movement. Anything you can do to reduce humidity and increase air movement will make your house and garden less attractive to midges. Closely mown lawns, sparse vegetation around your house and minimal surface water in the garden will decrease humidity and increase air movement, minimising resting places for midges. Also avoid gardening or watering in the afternoon and early morning. Biting midges can penetrate ordinary flyscreens. During peak infestations, midges have been known to enter houses looking for blood meals. Increase air movement in the house by using electric fans. Fans can effectively create an area unsuitable for biting midges as their activity reduces in wind speeds of over 6 to 8 kilometres an hour. Spraying residual (surface) insecticide on your flyscreens will help deter midges from entering your home. Burning mosquito coils inside can also reduce numbers. Most insect repellents are effective against midges and should be used whenever you are outside the house.

City of Gold Coast (the City) officers conduct regular monitoring and surveillance programs of the larval biting midge population throughout the tidal canal systems and waterways on the Gold Coast.

Mosquito coils and most insect repellants are effective a�ainst mid�es.

Biting midges You can take a big step towards living with midges by making sure you are protected. Biting midges, often referred to as midges, prefer humid overcast conditions with minimal air movement. Anything you can do to reduce humidity and increase air movement will make your house and garden less attractive to midges.

Closely mown lawns, sparse vegetation around your house and minimal surface water in the garden will decrease humidity and increase air movement, minimising resting places for midges. Also avoid gardening or watering in the afternoon and early morning.

Useful tipsPersonal reaction to bites varies from slight redness which disappears in half an hour or less, to severe inflammation. If you react rapidly and the swellings are small, you are reasonably immune so treatment may not be needed and the swelling and itch will soon go away.

For these less severe cases, the following tips may help reduce the effects of bites:

• A hot bath may provide temporary relief.

• Antihistamine creams or lotions from the chemist are quite effective, but do not apply them when the skin is broken.

• Some insect repellents also give relief to the bite, providing the individual’s skin is not sensitive to the repellent.

• If you react hours or days later to a bite, whether you felt the bite or not, your immunity is poor and you are likely to be more severely affected. If your reaction is very severe, consult your doctor.

Interesting facts about midges• Biting midges and sandflies are the same insect.

• Midges are present on all continents except Antarctica. Adults are about 1-2mm long, much smaller than the mosquito.

• The midge life cycle from egg to adult, is no more than eight weeks.

• Midges do not breed in grass, trees or other foliage, they only harbour in these areas.

• Midges are not known to be carriers of any human disease in Australia.

• In overcast humid weather, midges are known to bite day and night.

• Midge numbers will increase around the time of the full and new moons.

Only the female bites because she needs a blood meal to produce viable eggs. Midges are known as pool feeders because they use their proboscis like a saw to create a tiny hole in the skin (into which a pool of blood can flow). Saliva is injected into the pool to help the flow of blood. It is this saliva that causes the allergic reaction and itching.
