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:
- An in-house pest control team to carry out the vector surveillance and control work.
- External Pest Control Operator (PCO) to supplement the in-house vector surveillance and control.
- Source reduction and effective drainage as the main forms of mosquitoe control.
- 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.
- Apply larvicides or Anti-Mosquitoe (AM) oil to supplement source reduction.
- Thermal fogging is discouraged and shall only be carried out in accordance with the criteria stated in Code of Practice for Environmental Control Officer.
- Store food in rodent-proof storage containers/cabinets with at least 60cm clearance above ground.
- Remove food waste daily and clean the bins regularly.
