Aberdeen typhoon shelter and Ap Lei Chau
The shelter area has fishing boats moored close to older waterfront buildings and seafood-processing stalls, with high humidity and frequent movement of goods and clutter — plenty of room for cockroaches and rodents to establish. Ap Lei Chau's dense residential blocks commonly see shared drainage systems act as pest routes. Mosquitoes have a number here too: the Aberdeen and Ap Lei Chau mosquito-trap index reached 14.7% in July, a clear rise from June's 9.2% — standing water in older waterfront blocks (back-lane drains, rooftop clutter) is the main source.
