The CSD sprays for mosquitoes through our Vector Control District – the only one in Calaveras County. We have placed larvacide for 10 of the 11 varieties of mosquitoes that live in our district and that should control those mosquitoes. The 11th variety requires spraying and this spraying, as in years past, is typically done on Thursday nights (when surveillance or nuisance reports warrant) throughout the summer to help control these pests.

We use a spray that is non-harmful to humans and pets but you should close your windows and doors when you hear the sprayer approach.

Should you need assistance, want additional spraying for a special event, or have questions contact Greg Hebard, the CSD Site Manager, at 785.0100.
