Aedes aegypti Surveillance
Aedes aegypti mosquitoes are not native to San Mateo County, so the District’s goal is to completely eradicate them from our county. This is a difficult task, but to date the District has been able to keep the Aedes aegypti population very small and prevent these mosquitoes from spreading beyond the site of their initial introduction in Menlo Park.
A detection (as designated by a colored star on the Aedes aegypti maps below) means that one or more Aedes aegypti adults, larvae, or eggs was found at that site. The accompanying tables describe what was found at each detection - eggs, larvae, or adults.
The year-to-date surveillance report describes the number of each type of trap used and the number and species of mosquito collected in each trap.
