ABSTRACT
As Aedes mosquitoes increasingly exploit cryptic and unconventional aquatic habitats, traditional vector control methods face unprecedented challenges. This study details the entomological investigations and intervention strategies implemented during a prolonged 45-day dengue hotspot (13 cumulative cases) at Perumahan PGA, spanning from October to November 2025. A multi-pronged vector management approach was executed Surveillance included entomological investigations (E), sticky cvitrap deployment, virus detection in mosquitoes (VDIM) via NS1 antigen kits, and post-spraying bioassays. Active interventions involved intensive larviciding with Vectabac WG in subterranean manholes and the deployment of 300 Aedes-tech Mosquito Home Systems (AMHS) across the affected residential blocks. An El of 98 houses revealed significant cryptic breeding of Aedes aegypti and Aedes albopictus in overlooked indoor sites, specifically sink pipes and toilet bowls, as well as in closed concrete drains VDIM analysis successfully identified dengue-positive adult Ae. aegypti circulating within the hotspot. While chemical spraying achieved up to 100% mortality in adult mosquito bioassays, ovitrap surveilance indicated resilient breeding activity (up to 37% positivity in Block D) sustained by inaccessible vacant properties and unmaintained roof gutters. Unconventional indoor cryptic breeding sites heavily sustain localised urban dengue outbreaks. Eradicating such hotspots necessitates a strategic shift towards targeting hidden habitats using persistent biological larviciding, innovative auto-dissemination traps such as AMHS, and strict community management of indoor water traps.
