Manteca mosquito spraying starts today
Placeholder Image

They’re back.

The warming weather and extensive rainfall has made the South County ground zero for breeding mosquitoes.

The perfect conditions for mosquito breeding means the sometime deadly West Nile Virus will have more opportunity to spread.

In a bid to reduce the public health risk the San Joaquin County Mosquito & Vector Control District is preparing to conduct adult mosquito control operations today and Saturday.

Ground spraying for adult mosquito control using MGK Pyrocide 7396 or Evergreen 60-6 is scheduled today between 5 a.m. and 9 a.m., or Saturday, April 30, between 5 and 9 a.m.

The spray areas are:

• South Manteca/Wetherbee Lake Area: North to Wetherbee Lake, south to Williamson Road, east to S. Woodward Ave, and west to S. Oak St.

• South Rural Manteca: North to Division Road, south to the San Joaquin River, west to the Stanislaus River,  and east to Airport Way

• San Joaquin River Club: On the Westside of the Airport Way bridge.

People can access spray information and spray schedules by calling the District at (209) 982-4675 or toll-free at 1-800-300-4675 during business hours from 7 a.m. to noon and 12:30 p.m. to 3:30 a.m., Monday through Friday or by visiting the District’s website online at

Spraying for adult mosquitoes is done near sunset or sunrise with trucks and airplanes when mosquitoes are most active. The district will be using sprayers that apply a very fine mist of material that kills adult mosquitoes on contact.
