Intact flyscreens on all windows and doors will prevent mosquitoes entering. The main species that tend to enter houses are those that breed around houses. Thus it is important that any container that can hold water be emptied or removed. This is very difficult to determine. Currently there are different theories as to the level and amount of climate change.
Some models predict large changes in rainfall patterns, while other predict small changes.
We may expect with increases in rainfall there would be an increase in mosquito numbers and a subsequent increase in mosquito-borne diseases, however this may not be the case. The biology of mosquito-borne diseases is a very complex issue and involves the mosquito vector, reservoir hosts and even sociological factors. All we can be certain of, with global warming, is that there will be a change in the amount and distribution of disease, but to what extent, it is not known. There is some debate as to the presence of Lyme disease in Australia. Some workers believe that it is here.
