Ominous Amount of Mosquitos Haunting Sydney

--> It has been widely announced that last year (2014) was one of the hottest in history. In Australia, this follows in the wake of 2013, which was considered the hottest year ever recorded by the country.
 
The normal shape of pest inhabitance in the southern city of Sydney follows a typically seasonal pattern: in the summer, all the things people hate--mosquitoes, spiders etc –are blown south and reproduce for a short time before freezing to death in the colder winter months. Essentially, providing a restart to the pest populations of the city.

However, due to the unusually warm years, not enough of these bugs are disappearing.  This means an increasingly annoying—and from a public health standpoint—worrying number of aedes aegypti (also known as the yellow fever mosquito) and aedes vigilax (also known as the saltmarsh mosquito) establishing populations in the city of Sydney…and not buzzing off in the winter.

Public health workers fear that the increase in mosquitoes might herald a soon to be increase in disease. While yellow fever is not found in Australia, it is still not a good idea to have a large population of ready and potential reservoirs for the virus. Of concern however is the possibility of A. aegypti transmitting one of the equally deadly diseases that do occur in Australia: dengue fever, ross river fever or Murray valley encephalitis.  A. vigilax  is known to be responsible for a large number of Ross River fever cases.

If the warm weather keeps up, Sydney may need to take some action into its own hands to stamp out this dangerous vector. Time to get the buzz kill.
