In Vizianagaram, a new method is being used to control the spread of mosquitoes. Chemical balls are being prepared and placed in open drainages and canals. The chemicals in the balls spread their fumes in the atmosphere, restricting mosquitoes. These balls that are made out of pieces of cloth and sawdust and dipped in chemicals, are being used all over the district.
