Service Requests in March 2020

This table contains the number of each type of service request in March 2020 compared to the five-year average in March. Total service requests are lower this March compared to the five-year average. This variance is largely because the District pared back operations, including service requests, in observance of the county and state-wide shelter-in-place orders issued in mid-March.

March 2020 CO2 Trap Results

The following table and graph show the average number of mosquitoes collected per CO2 trap per night during the month of March compared to the five-year average for the six most common mosquito species in San Mateo County. Counts for all species are averaging below five per trap night, which is consistent with the five-year average. The numbers are expected to remain low until after spring rains.

Mosquito Larval Collections from March 2020

Surveillance for mosquito larvae is a priority in late winter and early spring, as seasonal water sources fill with rain water. A technician uses a dipper to take a sample of the water and visually inspects it for mosquito larvae. If larvae are present, the technician transports the sample to the laboratory for counts and identification. This March, 109 larval samples were submitted to the laboratory. The most frequently occurring species in larval samples was Culiseta incidens, the cool weather mosquito, present in 48 of the 109 samples.

Service Requests in February 2020

This table contains the number of each type of service request in February 2020 compared to the four-year average in February. Total service requests are somewhat higher this February than the four-year average. This variance is largely because of slightly higher numbers of mosquito, yellow jacket, and mosquito fish requests, perhaps because of early spring-like temperatures. The “Other” category of requests in February included as variety of service calls, including complaints about crane flies, broken pipes, ticks, bees and flies.
