Mosquito Prevention

Tulare County has three (3) vector control districts that cover most of the county. We may see an increase in mosquito activity this season due to the increased areas of standing water from the March 2023 flooding.

There are areas of the county that are not covered by a vector control district. Refer to each induvial website for coverage area information. If your area is not covered you may need to contact a private pest control company for abatement services at your cost.
