A rising number of adult mosquitoes has prompted the San Joaquin County Mosquito and Vector Control District to prepare to spray pesticides this week.
The agency will use MGK pyrocide 7396 or Evergreen 60-6 against concentrations of mosquitoes from 3:30 to 6 a.m. Thursday and Friday.
West Ripon and southwest Manteca are expected to be sprayed. The pesticides are applied with a fine mist that immediately kills adult mosquitoes.
