The mosquito fogging will not harm you.

The mosquito fogging being conducted by the Vector Borne Disease Control Program (VBDCP) will not harm humans.

The aim of the mosquito fogging operations is to kill, or “knock-down”, any adult dengue mosquitoes that may be carrying the dengue virus. The mosquitoes become infected with the virus after biting and taking blood from someone is sick with dengue. To try and prevent the infected mosquito from biting another person and passing on the disease, the VBDCP is applying the mosquito fog in areas where a lot of dengue cases have been reported.

The insecticide used in the mosquito fogging is a synthetic pyrethroid that is very similar to the insecticides used in most domestic insect spray cans that are found on supermarket shelves. The ‘fog’ is created by blasting the mixture of insecticide and water into very fine droplets through the fogging machine. The amount of insecticide in the fog is very small, and is dispersed at quantities that can only kill something as small as a mosquito, so at the concentrations used there will be no adverse health effects on people who are occasionally exposed to the fog.

Things to do if fogging at your residential area

  • Close the closet / wardrobe
  • Cover food / kitchen utensils
  • Open the window / door
  • Wear a face mask

Temephos affects the central nervous system through inhibition of cholinesterase. In larvae, this results in death before reaching the adult stage.

Temephos is widely used and applied by both private and public pest control in areas of standing water


  1. Small amount water collect place, undisturbed (<10L capacity) such as gully trap, flowerpot holder, toilet bowl, pails, small containers, etc.
  • Apply 1 g TEMEBATE per application
  1. Medium size containers (>10-20L capacity) such as cistern, barrels, water tank, plastic pails, etc.
  • Apply 2 g of TEMEBATE per application
