The District was formed in 1947, originally as the Orange County Mosquito Abatement District, in accordance with local authority provided by the Mosquito Abatement Act of 1915 and further supported by the California Health and Safety Codes. The District was responsible for protecting the growing population of Orange County from mosquitoes and mosquito-borne diseases. In 1975, the Orange County Board of Supervisors conducted an efficiency study that concluded that the District could effectively assume the responsibility for comprehensive vector control. Consequently, fly and rat control, formerly part of the Orange County Health Department, was transferred to the District. At that time the name of the District was changed to the Orange County Vector Control District. In 2004, the District reestablished a Red Imported Fire Ant program after the State stopped funding the program they had established in 2000. In 2015 the name of the District was changed to the Orange County Mosquito and Vector Control District. Operation of the District is overseen by a Board of Trustees comprised of 35 members, each appointed by their city of residence (34) with one member representing the County. Trustees are appointed for terms of two or four years. The current budget approved by the Board of Trustees supports District activities in providing vector control services to County residents. Funding also supports education programs on vectors that are presented by staff at school and civic group meetings. The District also has printed material available to the public upon request that describes what citizens can do to keep their homes and property free of rats, flies, and mosquitoes, Red Imported Fire Ant, and pests that may be found around the yard and inside the home. What is a Special District? Special districts are created and funded by a community’s residents to provide new or enhanced local services and infrastructure. Local residents own special districts and govern them through locally elected or appointed board members. California Special Districts are passionate about providing high-quality services and resources in the most efficient and effective manner.

Mosquitoes Rats Flies Red Imported Fire Ants Diseases Vectors Carry Sterile Insect Technique Informational Brochures Control Products FAQs Flies There are about 160,000 known species of flies. They are found everywhere in the world — even in Antarctica. Flies have only two wings and belong to the order of insects called Diptera, which means “two wings.” Many flies are beneficial; several are involved in plant pollination, others are predators or parasites of other insects. Flies that reproduce in animal excrement, food waste, and garbage are called filth flies. Two common species are house flies and bottle flies. Filth flies are a nuisance as well as carriers of organisms that cause diseases in humans and domestic animals. The Common House Fly The common house fly ( Musca domestica ) is a nuisance as well as a carrier of diseases to humans and domestic animals. In two weeks, one fly may lay more than 1,000 eggs in animal excrement, garbage, kitchen refuse, piled lawn clippings, and other decomposing plant and animal matter. In warm weather, the life cycle (egg to adult) usually takes eight days. Warm or protected environments may permit fly production year-round. In urban areas, the larval (maggot) sources of house flies can usually be found within the distance of a city block from where the adult fly was captured. Although adult flies may sometimes travel several miles from the source. Besides the grayish-black house fly, several other kinds of flies are found in the home. Control of these is the same as for the house fly, although the elimination of larval sources varies between species. Flies and Public Health Because many species feed on decaying organic matter and animal waste (including human waste), flies have been implicated in the transmission of several bacterial and protozoan pathogens including: E. coli, Salmonella, Shigella, Staphylococcus, Streptococcus, Giardia, and Trichomonas . In addition, they have been known to transmit parasitic roundworms and tapeworms. How to avoid a fly infestation There are effective methods and specific chemical products available for controlling flies. When purchasing a pesticide, it is important that the product label specifically includes "for the control of flies" on the label. Also, be sure to note the active ingredient in the product being purchased and follow all instructions to the letter!

Junior Inspectors Sterile Insect Technique (SIT) Aedes Mosquitoes, a.k.a Ankle Biters West Nile Virus Homepage Do-It-Yourself Solutions for Mosquito Issues Did you know? Many mosquitoes breed in small water sources in residential backyards, and they do not fly far from the source. Eliminating these small water sources can reduce the number of mosquitoes on your property. Search around your property for any standing water (indoors and out) and discard unused containers. Be sure to scrub unused containers thoroughly to remove mosquito eggs. Watch the “Meet Your New Neighbor” series of videos to learn about mosquitoes and how to eliminate them from your property. These three videos will provide information on: How to prevent mosquito breeding: Protecting yourself and family from mosquitoes: Treating for mosquitoes when necessary: Download and review the checklist to conduct a self-inspection on your property. Make sure to inspect your front yard, side, backyard, and inside the home. Use this checklist for guidance DIY Pesticide Options DIY Breeding Source Checklist What to expect: Eliminating water sources will not provide immediate results; adult mosquitoes die off in approximately 10 days, but eliminating water sources reduces the number of larvae and pupae that will eventually emerge into biting adults. Prevent mosquitoes from entering your home by keeping doors and windows closed. If windows and doors must be kept open, ensure your window and door screens are free of holes or tears. Wear an EPA-approved insect repellent to keep mosquitoes from biting you and your family. Other ways to help: Become a neighborhood advocate and sign up to pass out brochures and repellent wipes or share the links and information with your neighbors as these mosquitoes could impact your community.

Diseases Vectors Carry Sterile Insect Technique Informational Brochures Control Products FAQs Information Bulletins The Orange County Mosquito and Vector Control District is frequently asked to assist a resident with a problem caused by a pest not controlled by the District. We limit our activities to those species determined to be vectors by the California Health and Safety Code. The District currently has control programs for mosquitoes, rats and Red Imported Fire Ants. Our staff is not trained or equipped to perform control activities on vectors and/or pests like Africanized honey bees, opossums, gophers and raccoons. However, we do have information sheets on these and other pests available. These information sheets contain suggestions for both exclusion and control of various other vectors and pests that can be performed by the homeowner. Often times the best control method is to eliminate conditions that attract the pests. This strategy is our first step in controlling vectors, and it works well with nearly all pests.
