(KGTV) -- Summer is nearly here, and the County is preparing for pests. On Wednesday, the first rounds of larvicide will be dropped on 48 rivers, streams ponds and waterways.
In previous years, crews sprayed neighborhoods by hand to fight mosquito-borne illnesses like Zika and West Nile viruses. This year, the County will use a helicopter to drop the batches or solid, granular larvicide on the waterways that cannot be treated by hand.
The drops will take place about once each month of mosquito season (April to October). Mosquito larvae that ingest the larvicide will be killed, but the larvicide is not harmful to people or pets.
