The slum areas have been affected due to heavy rains that have led to the collection of water in small areas. Hence, in order to deal with the issue of mosquito breeding, the Kolkata Municipality in Bidhannagar has started deploying a drone to fly around and locate mosquito larvae, dirt, and stagnant water. The civic workers often fail to reach the rooftops of high-rise buildings, where temporary water patches, empty plastic teacups, and water containers serve as potential mosquito breeding grounds. The roofs are under the control of the builders, who do not give access to the civic staff. Drones will help them identify the areas that have become mosquito breeding grounds. Over the years, the breeding season of the mosquitoes has changed. This has caused serious problems to the civic bodies in carrying out anti-larvae drives.

The district magistrate has provided to deploy drones in North 24-Parganas, where there has been anoutbreak of dengue in some pockets. Many people living in Ashoknagar, Habra, Barrackpore and Naihati are suffering from dengue.
The exercise started from Bali Math in Duttabad area of Salt Lake in the presence of Mayor Krishna Chakraborty and several health officials. Chakraborty said, “It is raining heavily here and water accumulates from place to place which makes it difficult to monitor and detect mosquito breeding sites.”
Moreover, according to the municipality, using smoke and oil (to clear mosquito larvae) faces many problems.
