Mosquitoes

  • The mosquito has 4 stages in their life cycle, namely egg, larva, pupa and adult.
  • The adult is an active flying insect, while the larvae and pupae are aquatic and occur only in water.
  • A Complete life cycle will normally take from 7 - 10 days (variation depends on the species of mosquitoes and the environment conditions such as temperature, humidity and food).
  • Depending on the species, a female mosquito lays between 30 to 300 eggs at a time.
  • The adult mosquito can live for 3 weeks to a month.
  • Different species have different host preference, biting habits, resting habits and breeding habitats. These behaviours are important when considering the choice of control methods.
  • Mosquito species commonly found in Singapore include:

Aedes Anopheles Culex
Aedes aegypty Anopheles sundaicus Culex Tritaeniorhynchus
Aedes albopictus Anopheles maculatus Culex Gelidus
Culex Quinquefasciatus

Signs of infestation: flying adults, larvae/pupae in stagnant water.

Why Control Them?

  • Transmit diseases such as Dengue Fever, Zika, Malaria, Chikungunya, Yellow Fever, Filariasis and Japanese encephalitis
  • Cause nuisance, as they bite people
  • Reduce the outdoor recreation
  • Violation of laws (heavy fine, stop work order)

What we do:

  • Inspection for mosquito breeding habitats /potential mosquito breeding habitats.
  • Larviciding will be carried out on breeding habitats / potential breeding habitats.
  • Other chemical methods will be used as a complementary control measure, for example ULV or thermal fogging will be carried out when the adult mosquito population is detected.
  • Advise client on structural enhancement, removing of potential breeding habitats, where possible.
