Environmental health teams will increase inspections in residential areas where dengue case numbers have climbed in recent weeks.
Officers are focusing on roof gutters, flower pot trays, and other common breeding sites. Fines may be issued where repeated lapses are found.
Residents are encouraged to practise the five-step Mozzie Wipeout routine and report stagnant water in common areas to their town council.
The National Environment Agency said case clusters in the past fortnight have been concentrated in landed housing estates and older condominium blocks where roof gutters and plant saucers are common breeding sites. Officers will distribute educational leaflets and conduct door-to-door checks in affected neighbourhoods.
Community volunteers have been enlisted to help identify vacant units and construction sites where water may accumulate unnoticed. Town councils said they will trim overgrown vegetation near drains to improve visibility during inspections.
Health officials reminded residents that early symptoms of dengue include sudden fever, joint pain, and rash. Those feeling unwell should seek medical attention promptly and use mosquito repellent during daylight hours when Aedes mosquitoes are most active.
