Right now, Yolo County has two human cases of the virus but in the mosquito population it’s at epidemic levels and County Health Director Doctor Bette Hinton says they need to stop the spread now.
"We’re concerned that we don’t get a human epidemic instead of just a mosquito epidemic."
But spraying insecticide over urban areas doesn’t sit well with residents like Julie Partansky – a former mayor of Davis and member of “Stop West Nile Spraying Now.”
"Can you spray yourself out of this situation? All that stuff, it’s made to kill, it’s not a benign substance and do we really want all of that material sprayed over our city."
Mosquito control officials say aerial spraying is the best way to stop the spread of West Nile virus. Spraying is set to start at sundown.
