The Allegheny County Health Department will start treating storm water catch basins in Pittsburgh Monday with pesticide to combat mosquito breeding.
The pesticide, which is nontoxic to humans, pets and aquatic life, does not kill mosquitoes directly, but stops their maturation process. The mosquito eggs become stuck in a larvae stage and are eaten by other organisms.
Dr. Ronald Voorhees, acting director of the health department, said treating the water catch basins makes a serious impact on the mosquito population.
