San Joaquin County Mosquito and Vector Control District spraying Lodi

LODI -- Mosquito-control efforts are scheduled as early as Saturday evening (Aug. 4) in nearly all of Lodi’s residential areas, San Joaquin County Mosquito & Vector Control District officials announced Thursday.

Gov. Arnold Schwarzenegger declared a state of emergency Thursday in San Joaquin, Colusa and Kern counties because of the large number of cases this year of West Nile virus, a disease carried by mosquitoes.

All of Lodi, with the exception of areas east of Highway 99, are scheduled for spraying – weather permitting -- as are Stockton, Manteca, and northwest San Joaquin County. The spraying will continue at least through Wednesday. The district is using pyrethrins and piperonyl butoxide, insecticides found in products to eliminate head lice but low in toxicity to fish, birds and bees.

The public is advised to avoid direct contact with the spray, but no other safety precautions are necessary, according to the district. Control measures are performed near sunset or sunrise, when mosquitoes are most active.

To obtain additional information on West Nile virus including local mosquito control activities, call the district’s information line at (209) 469-8200 or at

So far in 2007, there have been two reported West Nile virus cases in San Joaquin County residents, one resulting in a fatality. The disease has been found in 22 dead birds and five sentinel chickens and one squirrel.
