Mosquito season is local, but West Nile tracking is statewide

California's West Nile Virus site gives residents a statewide place to check activity, report dead birds, and connect the issue back to local mosquito control.

Mosquito season feels local because it is local. A backyard bucket can matter. So can an old pool, a creek edge, a wet spring, or a warm week. West Nile tracking adds a state map to that local issue.

California’s West Nile Virus site is the state place to check activity and report dead birds. Local mosquito or vector control districts handle much of the ground work. That can include inspections, traps, and neighborhood help.

The home habit is small. Dump standing water. Fix screens. Use repellent when mosquitoes are active. Report dead birds through the official site. If bites are heavy around a property, contact the local vector control district instead of guessing where they are breeding.
