Mosquitoes

Mosquitoes are common flying insects. Most mosquito problems are caused by saltmarsh mosquitoes. More breeding occurs in freshwater after heavy rain. Regular high tides cause tidal marshes to flood, triggering mosquito breeding. 

 To prevent mosquitoes in and around the home, windows and doors should be screened. Empty all water-holding containers in the garden. These include pot plant saucers, tires, roof gutters, and tins. This will prevent breeding. Bed nets are an effective barrier at home or camping. Insect repellent and coils around the house can help keep mosquitoes at bay.

People vary in their sensitivity to mosquito bites. Most only have a mild reaction, but some have severe symptoms. If the bites are scratched, they may become infected, especially on the lower limbs. The classic “mozzie bite” is an itching, inflamed lump on the skin. Clean the bite with warm soapy water and dry the bite with a clean cloth. Application of a cool compress (i.e., icepack wrapped in cloth) can reduce inflammation. Seek medical advice if there is development of any other symptoms or signs of infection.

Local council may use fogging in outbreak areas to kill mosquitoes. This helps prevent diseases like Dengue, Ross River, and Barmah Forest. They are spread by mosquitoes and can only be confirmed with blood tests. 

Sand Flies

Sand Flies (biting midges) are so small (1.0mm – 3.0mm) that they often go unobserved by the individual being bitten. Sand flies are bad fliers. They get carried easily by wind. So, they are a common and annoying pest that comes in swarms.

Sand Flies are most active at sunrise and sunset. So, to stop sand flies in and around the home, window and doors should be screened. Trees and plants should be kept trimmed. Fans should be used in summer to blow them away. And, mosquito coils should be used outdoors. You can protect yourself from being bitten by wearing insect repellent. Also, by covering up at the times of day when bites are most common.

A bite from a small sand fly can be more painful than the bite of a large mosquito. Sand fly bites can also produce rashes and cause fevers depending on the tolerance to the bite. Apply an ice pack on the site of bite to prevent swelling, itching, and soothe the skin. Wash the site with soap and apply an anti-septic cream or lotion. Seek medical advice if there is development of any other symptoms or signs of infection.

Insect Repellents

Some insect repellents will contain warnings about age limitations for use on children. Yet, it is not recommended to use topical repellents on children under 3 months. Avoid topical repellents for babies when possible. Use physical barriers like netting for prams, cots, and play areas instead. Repellents have <10% DEET or picaridin. They are safe if used as directed on the label. Most importantly, children should not apply their own repellents. Carers should be careful not to use too much repellent. When putting repellent on children, apply it to the carer's hands first. Then, put it on the children's skin. You only need to apply a thin, even layer of repellent. Many see them as safer. But, remember that botanical repellents may still irritate skin. They should be applied according to the label.
