Mosquito Control Activities
Current Activities - Truck-Mounted Ultra-Low Volume (ULV) Applications
UPDATED APPLICATION DATES AND TIMES: In an effort to reduce the number of mosquitoes, interrupt virus transmission, and protect the public from mosquito-borne diseases, the District started ultra-low volume adult mosquito control applications in residential areas where mosquitoes infected with West Nile virus (WNV) were trapped. In Coachella, the application area is within Avenue 52, Tyler Street, Avenue 54, and Calle Empalme. In Indio, the truck-mounted application area is within Terra Lago Parkway, Harrison Street, Avenue 44, Aztec Street, and Vista del Oro, excluding agricultural areas and water bodies. The additional applications were delayed because of weather conditions and will be rescheduled for Thursday and Friday, May 23 and 24 between 3:00 and 6:00 a.m. Application dates and times may change due to weather. See route maps below.
Signs will be posted along the route informing residents of the control efforts. All control products used by the District are registered by the Environmental Protection Agency for the purpose of controlling mosquitoes and protecting public health. The products are applied according to label instructions by trained and certified technicians. Although mosquito control pesticides and the techniques used pose low risks, the District recommends that people who want to avoid exposure as a best practice, stay inside or away from the application area during and for 30 minutes following the application. For more information during treatment, please call (760) 541-2057. During regular office hours Mon-Fri, 7:30 a.m.-4:30 p,m, the public may call (760) 342-8287.
General Information - 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, 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 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 firstname.lastname@example.org. To be notified via email of any adulticiding activities, please sign up for notifications here.
