Do you have a risk of mosquitos in your workplace?

Mosquitos are the deadliest animal and with Japanese encephalitis now in Australia it is important to reassess the risk in your workplace.


  • Mosquitoes cause at least a million deaths every year.
  • There are about 700 million cases of mosquito-borne diseases occur annually.
  • With over 3,500species of mosquitoes, there is an estimated number in the quadrillions of mosquitos.
  • Only female mosquitoes bite. Both males and females feed mainly on fruit and plant nectar, but females also need the protein in blood to help their eggs develop. 
  • The females “bite” with a long, pointed mouthpart called a proboscis. They use the serrated proboscis to pierce the skin and locate a capillary, then draw blood through one of two tubes. The bumps or “bites” that we see form on our skin are actually an allergic reaction to mosquitoes’ saliva. When the mosquito feeds on human blood, it injects saliva into our skin, and the itchy bump is the result of a mild immune system reaction to it.
  • Mosquitos are usually active from dusk to dawn and tend to like dark, damp areas near stagnant water.
  • A mosquito can drink up to three times its weight in blood, although it’s very difficult for someone to die from blood loss caused by a mosquito.
  • Mosquito-borne diseases and illnesses are caused by bacteria, viruses, or parasites transmitted by mosquitoes. They can transmit diseases without being affected themselves.
  • The instances of mosquito-borne diseases have skyrocketed in the past years

  • Tall grass
  • Standing (still) water
