Due to the detection of West Nile virus activity and elevated mosquito
abundance, the District will conduct an adult mosquito spray treatment on
August 5th., 2021, followed by a wide area larvicide application on August
6th., 2021. 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 Aqua-Reslin (EPA Reg.
432-796) on August 5th., 2021 and Vectobac WDG (EPA Reg. 73049-56) on August
6th., 2021. Both control products are approved for use in mosquito control
by the US EPA. We have been working hard to use Integrated Pest 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 will be
posted on August 3rd., 2021 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 the District at 951-340-9792.
