The Chennai Corporation has stepped up its drive against mosquitoes in the city as residents in various areas have complained that the menace has intensified.
R.B. Saravanan, a resident of Nungambakkam, said the number of mosquitoes has been on the rise in the past few days. Residents of many other areas also complained of the nuisance caused by mosquitoes.
The civic body has employed over 1,300 workers for its special drive to control mosquitoes along water bodies, said a senior official of the Corporation. T. Nagar, Park Town, Anna Nagar, Korukkupet and Kodambakkam are some of the areas that require special attention, the official said.
Workers have started removing vegetation in the water bodies and are spraying larvicidal oil. The mosquito control operations are being carried out along the Cooum and the Adyar rivers and Buckingham, Captain Cotton, Otteri, Virugambakkam and Mambalam canals.
A total of 350 handheld fogging devices and 236 small fogging machines are being used. A stretch of 110 km waterways is being cleared of hyacinth by workers on nine catamarans and six fibre boats.
The entire length of the stormwater drains is also being covered. The mosquito density increased in many areas a week ago but the density has since started declining, the official said.
