Other Preventive Measures

☐ Turn pails and watering cans over and store them under shelter.

☐ Loosen soil from potted plants to prevent the accumulation of stagnant water on the surface of the hardened soil.

☐ Do not block the flow of water in scupper drains along common corridors in HDB estates. Avoid placing potted plants and other paraphernalia over the scupper drains.

☐ Cover rarely used gully traps. Replace the gully trap with non-perforated ones and install anti mosquito valve.

☐ Cover bamboo pole holders after use. Rainwater can potentially accumulate in these bamboo pole holders if they are uncovered and create a habitat.

☐ Trays or receptacles should not be placed beneath or on top of any air-conditioning unit as they may create conditions favourable for mosquito breeding. If there is a need for installation of such trays to address other issues, premises owners should ensure that they install HDB’s patented air-conditioner trays. Regular checks and maintenance of the tray is still necessary to ensure there are no chokages at the drainage point that could result in water ponding.

☐ Remove water in plant pot plates. Clean and scrub the plate thoroughly to remove mosquito eggs. Avoid the use of plant pot plates, if possible.

☐ Change water in flower vases. Clean and scrub the inner sides of vases. Wash roots of flowers and plants thoroughly as mosquito eggs can stick to them easily.

☐ Clear fallen leaves and stagnant water in your scupper drains and garden. These leaves could collect water or cause blockages to the drains, thus resulting in the buildup of stagnant water.

☐ Clear any stagnant water in your air cooler unit.

☐ Add prescribed amounts of sand granular insecticide into vases, gully traps and roof gutters, even if they are dry. 

☐ Clear away fallen leaves in roof gutters and apron drains. If structurally feasible, remove the roof gutters.
