Vectors are organisms that transmit diseases. In Singapore, there are five main vectors: mosquitoes, flies, rodents, cockroaches and fleas. As the majority of vector-borne diseases in Singapore are transmitted by mosquitoes, vector control mainly focuses on mosquitoe control.

Similar to earth control measures and noise control, contractors are required to submit a plan for their vector control ahead of the construction works which include but are not limited to the following:

  1. An in-house pest control team to carry out the vector surveillance and control work.
  2. External Pest Control Operator (PCO) to supplement the in-house vector surveillance and control.
  3. Source reduction and effective drainage as the main forms of mosquitoe control.
  4. In-house pest control team shall carry out search and destroy activities of any potential breeding grounds, especially after every rainfall, using the “zoning method”. This method divides the site into a maximum of seven zones and aims for a more effective vector surveillance and control by focusing on one zone per day.

  5. Apply larvicides or Anti-Mosquitoe (AM) oil to supplement source reduction.
  6. Thermal fogging is discouraged and shall only be carried out in accordance with the criteria stated in Code of Practice for Environmental Control Officer.

  7. Store food in rodent-proof storage containers/cabinets with at least 60cm clearance above ground.
  8. Remove food waste daily and clean the bins regularly.
