Aedes mosquito, which is the mosquito species type that causes dengue cases in Singapore lay their eggs on the water surface. Mozzies undergo a complete life cycle, develop as an adult and lie on the water surface to rest before taking off to source for blood feed. They rely on their siphon tubes to breathe by hanging upside water direction along the water surface. All they need is a tiny coin size of stagnant water presence for mosquito breeding to take place.

Here are some examples of common mosquito breeding sites:

  • Cans, containers, pails and buckets left in the open
  • Air-conditioning trays
  • Rain gutters, gully traps and drains
  • Wood and leave piles that can trap water

In addition, they require moisture to survive and reproduce. The life cycle takes around 3 weeks to complete and is more active during cooler climates such as early morning and late evenings. One main factor that can cause midges infestation is rainfall, temperature and water quality changes. If you notice swarms and heaps of midges found on the cars or windows, it is the fact that they are light and blown by the wind.
