Mosquitoes are not just a nuisance when they leave itchy bites on our skin or disturb us when they fly close to our ears. They are also deadly and are responsible for spreading diseases such as dengue fever, zika, Chikungunya and malaria.  The three most common mosquitoes found in Singapore are:

  • Aedes spp. – They are appeared in black and white stripes. They breed in unpolluted stagnant water, normally rest outdoor. The peak biting time is at dusk and dawn.
  • Anopheles spp. – They have spots on their wings. Active at night. Adult females usually bite and oviposit at night.
  • Culex spp. – They are appeared in dull brown colour. They breed mainly in polluted stagnant water, normally rest indoor. They bite throughout the night.

The life cycle for most of the mosquito species are within 1-2 weeks. Thus, weekly mosquito control is always strongly recommended.

Management Strategies

Mosquito Breeding Ground Detection


Larvicide is applied in potential mosquito breeding grounds to prevent larvae from maturing into adult stages.
Thermal fogging produces a very large quantity of small chemical droplets. It is effective in killing mosquitoes at large open areas as well as locations obstructed by vegetation, storage, other buildings, and terrain.
ULV misting is used indoors to create a space filled with insecticide. The chemical droplets produced are fine, thus ensuring even coverage with low volumes.
Chemical is misted on the vegetation to create a barrier between mosquito resting areas and inhabited areas. Provide long residual protection against adult mosquitoes.

Preventive Measures

  • Clean drains and roof gutters regularly and ensure there is no clogging.
  • Seal septic tanks, pump chambers, and effluent disposal system properly to prevent mosquitoes from entering.
  • Empty water-bearing receptacles (e.g., dish rack tray, tray below the refrigerator, air-conditioner tray, etc.) regularly.
  • Dispose unwanted items that can collect water (e.g., tyres, tin cans, fallen dried leaves, etc.) in the lidded containers or store them under shelter away from rain.
  • Ensure canvas or plastic sheets are laid properly without creating an undulating surface or if possible, avoid using them.
  • Change water in the pet bowls daily.
  • Replace ornamental plants with those that do not collect water.
  • Perforate holes on plant axils to drain off the collected water.
  • Loosen up hardened soils in the flower pots regularly to allow water seep through the soil.
  • Empty water from flower pot plates or avoid using them.
Use mosquito nets.
