    Adulticiding

    UPDATE (9/15/17): Due to continued mosquito-borne virus activity in the East Valley, the District will conduct aerial ultra-low volume (ULV) applications to lower the mosquito abundance and reduce the risk of disease transmission to humans by infected adult mosquitoes. Applications took place September 11-12, 9 p.m. to midnight and applications are scheduled 8-11 p.m., September 17-18, weather permitting. See the map below for details.

    Control of Adult Mosquitoes
    In the case of an increase in the number of mosquitoes in a particular area, or detection of an arthropod-borne virus in mosquitoes, wild birds, sentinel chickens or humans, the District may decide to conduct ground or aerial ultra low volume (ULV) adulticiding activities.

    Ground ULV is carried out usually in urban areas with special equipment mounted on the truck to control adult mosquitoes. Aerial ULV is usually carried out in rural areas by helicopter or small airplane. The adulticides are applied at very low dosages. The low dosages, plus natural degradation by UV light and water, ensure minimal risk. The District uses a pyrethroid-based products for ground and aerial ULV adulticiding. Pyrethroids are a synthetic insecticide, modeled after a botanical insecticide produced primarily from the flowers of Tanacetum cinerariaefolium, which is a species of chrysanthemum plant family, which acts as the plant’s own insecticide to keep insects away.

    At the time of adulticiding the District will post the information on its website as well as in the area. For questions, please contact 760-342-8287 or or email cvmosquito@cvmvcd.org. To be notified via email of any adulticiding activities, please click here.

    If you would like to request that ground adult control applications are not made to your property, please click here and the District will try to accommodate the request without jeopardizing public health.
