Parts of northeast Menlo Park, Redwood City and unincorporated county zones will be sprayed tonight for mosquitoes (Sept. 2) to curb the spread of the West Nile virus, according to the San Mateo County Mosquito and Vector Control District.
Mosquitoes carrying the virus were detected within the 94063 zip code on Aug. 28, and a bird tested positive on Aug. 27, district officials said. The area to be treated with insecticide tonight is roughly bordered by U.S. 101, Kentfield Avenue and Jefferson Drive.
Trucks will start fogging at 9 p.m. on Tuesday night and finish by 5 a.m. tomorrow. The treatment may be repeated if the virus is found in mosquitoes collected after tonight's spraying, according to the district. The fogging will only take place when wind speeds are below 10 miles per hour, according to district officials, to ensure that the chemicals remain within the targeted area. The district has been using Zenivex as the insecticide.
Mosquitoes transmit the virus through biting. Although the primary hosts are birds, it can also infect people, horses and other animals. Any standing pools of water should be drained to help prevent mosquitoes from proliferating, and people should use repellent and make sure door screens fit tightly, the district advised.
Contact the district at 344-8592 for more information or to request fogging in your area.
