Pre-monsoon showers have already begun in Thane, but the civic body seems unprepared for the heavy rains expected to lash the city by the third week of June. The Thane Municipal Corporation sprays medicines across the city every year to prevent the spread of mosquitoes that causes filaria, malaria and other diseases.

The TMC, which was supposed to complete the spraying projects before monsoon, has not even issued the tender to start the work even though the previous contract expired 10 months back, alleges social activist Kedar Dighe.
