Zika Mosquitoes in Inland Empire

Colton, CA

Aedes aegypti mosquitoes, carriers of the Zika virus, were found in Colton. One mosquito was discovered on June 15 and two were identified last October. To date, none have tested positive for the Zika Virus. In the meantime, Aedes aegypti mosquitoes were discovered in greater numbers in the Coachella Valley on May 9.  To date, none of these mosquitoes tested positive for the virus either; however, Vector Control has conducted truck-mounted and in some instances, aerial spraying, in an area that includes approximately 1700 homes. Late last week, Vector Control expanded its spraying efforts to include an additional 580 acres in Coachella Valley to eliminate what it called “a medium to large infestation." Treatment efforts are expected to continue through the summer.

The District is spraying a chemical called Pyrethrum, a botanical insecticide produced primarily from the flowers of Tanacetum Cinerariaefolium, a species of the chrysanthemum plant family.  Although experts claim the chemical presents low health risks, Vector Control suggests some people may prefer to stay inside or away from application areas for 30 minutes after spraying is conducted.
