A prolonged monsoon and tarpaulin sheets over terraces and roofs have brought the mosquito menace back to Shivaji Park, with breeding grounds forming in the accumulated water on top of the plastic sheets, residents have claimed. They have said that this has increased the chances of the spread of dengue and has forced people to shut the windows of their homes.

While the Brihanmumbai Municipal Corporation (BMC) officials claim that the complaint is not a new one and has been acted upon, residents said several flat owners continue to keep the tarpaulin sheets, that help prevent leakages, on top of buildings. The dengue-carrying mosquito species, Aedes aegypti, has a radius of about 2 km. And, these tarpaulin sheets, in which rain water collects sometimes, act as a breeding ground for the insects.
