A vector is any animal or insect that is capable of transmitting disease or is a public health nuisance. The GLACVCD controls mosquito, black fly and midge populations. Mosquitoes are of the highest concern for the District because they transmit diseases to humans.
The district is funded through ad valorem (property) taxes and benefit assessments.
No, we are an independent special district governed by a 36-member Board of Trustees.
Yes. West Nile virus is now endemic to Los Angeles County and remains a serious public health threat. It is important to continue taking proactive measures to prevent mosquito breeding around your home and prevent mosquito bites.
One in five people infected with West Nile virus will develop symptoms, which include fever, headache and body aches, nausea, a skin rash, and/or swollen lymph nodes. These symptoms can last several weeks to months. In severe cases, WNV neurological symptoms may occur as a result of encephalitis, meningitis, and meningoencephalitis. Severe symptoms may include high fever, headache, neck stiffness, disorientation, coma, tremors, paralysis, and possibly death. The time between the mosquito bite and the onset of illness ranges from 5 to 15 days in humans. If you start exhibiting signs of illness after a mosquito bite, contact your physician.
We cannot prevent West Nile virus from entering the area; however, reducing the mosquito population and educating the public on ways to prevent mosquito bites reduces the chance of WNV transmission and infection. The GLACVCD Scientific-Technical Services Department routinely surveys for mosquito-borne diseases such as West Nile virus, St. Louis encephalitis, and Western equine encephalomyelitis. Adult mosquitoes are routinely trapped and tested for these viruses. Sentinel chicken flocks are strategically placed and are tested for infection. In addition, wild bird surveillance provides an opportunity to test important reservoir hosts for infection. Vector Control Specialists survey the District regularly for sites where mosquitoes may breed and eliminate or control these as necessary.
The District posts warning signs in public places such as parks when recent surveillance in the area indicates the presence of disease activity such as West Nile virus. Signs are generally posted up to approximately ½ mile from the surveillance trap site to accommodate for the flight range of local mosquitoes. The black and red signs indicate that West Nile virus activity has been confirmed in the area and caution residents to take protective measures against mosquito bites. The signs also provide the District’s contact information for questions. People who work, live, and recreate in the area should be particularly careful when outdoors between dusk and dawn, as this is the time when the mosquitoes are most active and are most likely to bite. Use of mosquito repellent and long sleeved shirts and pants are the best defense against mosquito bites.
Yes. The Department of Community Affairs offers community presentations and various classroom education programs. The popular Mobile Education Unit offers a mobile, hands-on science lesson for 5th graders which complies with California educational standards. To book a presentation, contact Levy Sun, Public Information Officer at (562) 944-9656.
We ask that you provide us with the source type and exact location of the source, including street address, cross streets, and whether this is private or public property. We request contact information including contact phone number for any follow-up calls.
Yes. You can remain anonymous when reporting a source on a neighbor’s property. We do ask, however, that a contact number be made available for any follow-up calls, but this number will not be shared.
Any stagnant water source can be a potential mosquito breeding site. Stagnant water with algae, debris, and other organic materials is an ideal habitat for mosquito larvae. Since mosquitoes lay their eggs on the surface of the water, check for any mosquito eggs, egg rafts, or larvae.
Weather conditions play an important role in the mosquito life cycle. In warm summer months, a puddle of stagnant water can become an ideal breeding source in several days.
Treat the accumulated water with chlorine and other approved chemicals to prevent mosquito breeding. Notify the Greater Los Angeles County Vector Control District and we can place the pool on our routine treatment route. Upon request, the District will also deliver free mosquitofish to residents for placement in backyard swimming pools, ponds, and fountains as a form of biological control for mosquito breeding.
Our field specialists only treat the pool to prevent mosquito breeding using mosquitofish or chemical control methods. The treatment does not change the color of the water or clean the pool. Residents should contact a professional pool maintenance service to bring the pool up to working order.
All property owners with mosquito breeding sources are subject to legal abatement procedures under the State Health and Safety Code (SHSC Section 2060-67). Failure to comply with a legal public nuisance abatement procedure may result in civil penalties that range from $100 per day, including a misdemeanor offense (municipality ordinance), to $1,000 per day (SHSC Section 2061(b)(5)).000 et.seq.)
Your best defense against West Nile virus is to take proactive measures to prevent mosquito bites. Eliminate any potential mosquito breeding sources around your home by dumping and draining standing water. Avoid outdoor activities between dusk and dawn during the warm mosquito season since mosquitoes are most active during this time. When you are outdoors during this time, wear loose-fitting pants and long-sleeve shirts to decrease exposure to mosquitoes. Use approved mosquito repellents containing CDC appproved insect repellent containing the ingredients DEET or Picaridin. Be sure to read and follow the manufacturer’s directions for use.
