Due to the detection of West Nile virus activity and elevated mosquito
abundance Northwest Mosquito and Vector Control District (NWMVCD)
will conduct an adult mosquito spray treatment on August 24th, 2022,
followed by a wide area larvicide application on August 25th, 2022.
West Nile virus is transmitted to humans through an infected
adult mosquito bite. The spray application will be conducted between the
hours of 3:00 am to 6:00 am at the following location: the residential
neighborhood located in the City of Riverside, South of Magnolia Blvd. and
North of the 91 Freeway, situated between Van Buren Blvd. and Harrison St.
Please see attached images for exact spray route.
The District will be treating this area with DeltaGard (EPA Reg.
432-1534) on August 24th, 2022 and Vectobac WDG (EPA Reg. 73049-56) on
August 25th, 2022. Both control products are approved for use in mosquito
control by the US EPA. We have been working hard to use Integrated Vector
Management practices in these areas and the majority of our control efforts
focus on preventing mosquito breeding and killing mosquito larvae before
they become flying adults. However, due to West Nile virus activity and
elevated mosquito abundance detected, adult mosquito control followed by
wide area larval control treatments via truck mounted ground fogger will be
employed to control the current mosquito population in this area. Signs were
posted on August 22nd., 2022 in the spray area to inform the public of our
activities. Information regarding the treatment will be posted on our
website at www.northwestmvcd.org. If there are any questions or concerns,
please contact NWMVCD at 951-340-9792.
