Mosquito spraying taking place near the Willowick Golf Course this week

The Orange County Mosquito and Vector Control District will be conducting an Ultra-Low Volume (ULV) adulticide treatment to address the increase in mosquito abundance and risk of mosquito-borne disease in the City of Santa Ana.

The treatment will occur in an area bordered by W. 5th St., W. 11th St., N. Jackson St., and Harbor Blvd. If numbers persist or disease is present, treatments will continue throughout the biting season.

Reducing the population of adult mosquitoes with public health pesticides (adulticides) that are registered by the US Environmental Protection Agency (US EPA) will be done if necessary to prevent human illness or suppress a heavy nuisance infestation of mosquitoes. The decision to use mosquito control applications either by truck-mounted, backpack or aircraft application equipment will be based on surveillance information or the documentation of West Nile virus or other mosquito-borne disease activity at a level that indicates a threat to human health. Either Ultra-Low Volume (ULV) adulticide treatments or Wide Area Larvicide (WALS) treatments will be conducted in concentrated areas most at risk for disease occurrence or where travel-related mosquito-borne disease cases have been identified.
