With the rainy season barely two months away, the BMC has begun work on tackling the mosquito menace, which is responsible for several monsoon-related illnesses.  

The municipal body has drawn up a plan to eradicate mosquito-breeding spots in slums, residential buildings, and under-construction sites. This time, a BMC source said, guppy fish will be released at 66,959 water spots to reduce mosquito larvae. Using guppies is a tried-and-tested method to tackle the menace. They are left in stagnant water puddles where mosquitoes breed; the fish then eat the mosquito eggs and larvae, leading to reduced mosquito population.
