Dhaka North City Corporation (DNCC) is going to use a new insecticide for water bodies to kill mosquito breeding grounds on pilot basis.
According to officials, the new insecticide poses low risk to the environment compared to the present one being used. Named Novaluron, the tablet is manufactured by a company from England.
DNCC Deputy Chief Health Officer Lt Col Md Golam Mostofa Sarwar said, "These tablets will be disseminated at watery areas, which are mosquito breeding hotspots. Once used, the insecticide will be active for three months. A gram of the tablet can be used for 10 litres of water."
According to the official, even if mosquito eggs are laid and they hatch, the insects will not be able to fly due to the insecticide's effect.
"However, the tablet is not harmful for humans," he said, adding that currently, DNCC has 500 kilogrammes of tablets at their disposal, and more testing is required to fully implement the insecticide.
DNCC spotted 629 breeding grounds in areas under the corporation, and the tablets will be introduced from tomorrow, starting from Uttara Zone-6, and will continue for 10 days on pilot basis.
As breeding season of Culex mosquitoes starts from November, DNCC has started to work ahead to keep mosquitoes in check.
Currently, the corporation is using the liquid insecticide Temephos for killing larvae, and Malathion for adult mosquitoes.
