The Orange County Mosquito and Vector Control District plans to spray from 3 a.m. to 5 a.m. on Saturday, Monday and Wednesday between Edinger Avenue to Occidental Street and from Lowell Street to Van Ness Avenue. The poison will be applied via truck-mounted equipment, according to a news release. The products used are not harmful to people or pets and will not harm the finishes on cars or homes, according to the Vector Control District’s website. The targeted mosquitoes – small, black mosquitoes with white stripes – are not native to the region and are considered “aggressive day-biting mosquitoes.” They can transmit viruses like dengue, yellow fever and Zika. They also can transmit heartworm to dogs and cats.
