Don’t let mosquitoes spoil Independence Day!

Since we live in the desert and have very limited rainfall, the majority of mosquito breeding sites in the Antelope Valley are man-made, created by people when they over water their lawns or neglect their swimming pools. Photo courtesy: AVMVCD

LANCASTER – Fourth of July brings families and friends together to celebrate, have backyard BBQs and enjoy other outdoor activities.  Unfortunately mosquitoes will be out and about as well.

The Antelope Valley Mosquito & Vector Control District (AVMVCD) would like to encourage residents to enjoy the outdoors, while staying safe from mosquito bites and the diseases they can transmit.

“We advise residents to follow the ‘3 D’s of mosquito control’,” said District Entomologist Karen Mellor.  “That means Drain all standing water, Dusk and dawn is when mosquitoes are most active, and when we need to Defend ourselves by using insect repellent while outdoors.”

The AVMVCD has noticed an increase in mosquito activity in some areas. An unkempt swimming pool can create thousands of mosquitoes that will infest an entire neighborhood.  Therefore the district has been conducting door-to-door inspections of houses with pools.  “Our technician will help the resident identify the problem and will treat the water, if mosquito larvae are present,” Mellor said.  “The product will work for a month or so and give the home owner time to either clean or drain their pool and thereby eliminate mosquito breeding.”

The West Nile Virus activity in California has been higher than last year. To date there was one human case in Kern County, as well as 223 birds, 282 mosquito samples, and 2 chickens in 18 counties that have tested positive for WNV.

Residents are encouraged to continue reporting any dead birds to the California West Nile Virus Hotline at 1-877-WNV-BIRD (1-877-968-2473) or online at  Not all birds will be tested, but the data of dead bird clusters is vital in tracking and controlling the virus.

West Nile Virus is transmitted by the bite of an infected mosquito.  Although most people that are infected do not show any symptoms, West Nile Virus is a potentially debilitating disease.  Even ‘mild’ cases of West Nile Fever can cause patients enormous pain and discomfort for months.

District officials urge residents to take individual responsibility, and remember the 3 D’s protect yourself and your family from West Nile Virus:

  • DRAIN all standing water – Empty out small containers at least once a week, keep pools and spas chlorinated or drained, and repair all water leaks.  Conserve water and prevent mosquito breeding.
  • DUSK and DAWN – are peak activity times for mosquitoes.
  • DEFEND yourself – wear long sleeved shirts and pants and use mosquito repellents containing DEET, Picaridin, Oil of Lemon Eucalyptus, or IR3535 when outdoors during mosquito activity. Always follow instructions on the product label. Keep tight fitting screens on doors and windows to prevent mosquitoes from entering homes.

Also remember to:

  • Get FREE mosquito-eating fish (Gambusia affinis) for fish ponds, pools, and horse troughs.
  • Vaccinate your horses properly.
  • Report stagnant pools and other backyard sources to the AVMVCD.
