Mosquitoes found around the Georges River region are more than just nuisance-biting pests. Mosquito-borne pathogens, in particular Ross River virus, are regularly detected and there have been cases of human illness in the local area too. There is no mosquito control in the local wetlands so individuals need to take steps themselves to avoid mosquito bites. Long sleeved shirts, long pants and covered shoes will provide a physical barrier against mosquito but the use of topical insect repellents will be important too. There is a range of cheap, safe and effective repellents available in Australia. A repellents should be approved by the Australian Pesticides and Veterinary Medicines Authority (APVMA) who test for effectiveness and safety. There’s over 100 insect repellent formulations currently registered while dozens more unregistered repellents are commonly found for sale at various stores, markets and via online retailers. The best repellents contain either DEET or picaridin as these chemicals have been repeatedly demonstrated in testing to provide the longest lasting protection against a range of biting insects. Many reviews of the literature have shown that, considering the widespread international use of these repellents, there are very few adverse health impacts reported (keeping in mind that their use has probably saved many live from potentially fatal illnesses such as malaria or dengue).
There are other types of repellents available. The most common are plant-based products such as tea-tree, eucalyptus, lavender, cat mint and peppermint oils. These repellents vary in their effectiveness but generally provide less protection than DEET or picaridin and if you prefer to use these types of repellent, it is important to remember that they’ll will need to be reapplied more frequently to provide comparable protection. It isn’t all about choosing the right repellent, to prevent bites you’ve got to use it correctly. Regardless of formulation, there must be an even and complete cover of all exposed skin otherwise mosquitoes will find a way through. Reapplication is required after swimming or physical activity. Spraying repellent on clothes or giving a dab “here and there” isn’t going to provide protection. Although mosquito repellent patches and wrist bands have been registered they won’t “whole body” protection against mosquito bites. Using mosquito repellents is the best way to reduce the risks of mosquito-borne disease. If you’re out and about around the local wetlands and bushland areas, it is important to take measures to avoid mosquitoes so make sure you pack a tube of insect repellent in your bag this weekend.
