Staying Vigilant Against Mosquito Breeding
We thank Mr Xu Zhenqun for his letter, “Stagnant water from fallen palm leaves breeds mosquito larvae” (May 15).
The National Environment Agency (NEA) takes all mosquito-related reports seriously as part of our comprehensive vector control strategy. Upon receiving feedback on the fallen palm leaves near Block 265 at Bukit Batok East Avenue 4, our officers investigated the site and found no mosquito breeding in the area.
Source reduction is a key strategy for dengue control and eliminating stagnant water remains the most effective way to prevent mosquito breeding. Common breeding habitats for Aedes mosquitoes include domestic containers, flowerpot plates, ornamental containers, discarded receptacles, and planter boxes. NEA works closely with relevant stakeholders, such as Town Councils, to conduct regular checks and ensure that public areas are kept free from mosquito conditions.
As we are currently in the traditional dengue peak season from May to October, vigilance against mosquito breeding is especially critical. We urge residents to practise the B-L-O-C-K (Break, Lift, Overturn, Change, Keep) steps regularly to prevent mosquito breeding, and take personal protective measures through the S-A-W (Spray, Apply, Wear) steps.
Everyone is encouraged to sign up for notifications on NEA’s myENV app to be alerted on dengue clusters. Together, we can protect our communities from the threat of dengue.
