At this District, each mosquito control technician is assigned a geographic zone within the county. Currently our service area is split into 9 zones. During February the District rotated the majority of technicians into a different zone. In the picture above, technician Walter Bruj is treating a 12.5 acre marsh in East Palo Alto, which is one of the cities in his new zone. Due to the sheer size of the breeding area, technicians use an Argo all-terrain vehicle for this type of treatment. This type of treatment usually takes about an hour and a half to complete. In February, most areas of San Mateo County had over 7 inches of rain which has greatly increased the amount of area that staff are inspecting and treating weekly.
