Residents are urged to rid their yards of water-holding containers to eliminate invasive Aedes mosquitoes

This week, District staff will conduct additional mosquito trapping in the area and technicians will start a door-to-door campaign searching for containers that can hold standing water in people’s yards where this mosquito species commonly lays eggs. Technicians will also educate residents on how to prevent breeding and carry out control activities as needed.

The door-to-door campaign will be carried out within the area bordered by Deep Canyon Road, Fairway Dr., Toro Peak Road, and Vintage Dr. The location where Aedes aegypti was detected in Indian Wells is close to the border of Palm Desert where the District is already conducting a door-to-door campaign. Residents living in this area will receive notices Tuesday, November 7, to alert them about the presence of the mosquito and the upcoming control strategies. Door-to-door inspections are scheduled to begin in Indian Wells on Thursday, November 9.

Invasive Aedes mosquitoes are small (about ¼ inch), black and white, and feed almost exclusively on humans, biting aggressively all day long. To eliminate this mosquito people need to eliminate all possible standing water sources where mosquitoes lay eggs. The public plays a critical role in helping to control the spread of this mosquito population. Aedes aegypti was first detected in the Coachella Valley in the City of Coachella in May 2016 and has since been detected in Cathedral City, Indio, La Quinta, Palm Springs, Palm Desert, and the unincorporated community of Mecca.

The District recommends that people making plans to travel to areas with active transmission of chikungunya, dengue, and Zika viruses protect themselves from mosquito bites by applying repellents containing EPA-registered ingredients, and wear long sleeve shirts, long pants, socks and shoes. Individuals infected with these viruses may experience symptoms, such as fever, headache, joint pain, muscle aches, seizures, rashes, and in rare cases, death. Should people experience any of these symptoms after returning from an area where mosquito-borne diseases are transmitted, the District urges them to protect themselves from mosquito bites locally and to contact their health care provider. Residents can check mosquito-borne disease activity ahead of their travels by visiting

How residents can help reduce mosquitoes:?

  • Drain Standing Water. Mosquitoes lay eggs in and near standing water. Limit the number of places for mosquitoes to breed by draining/discarding items that hold water, such as old tires, buckets, and empty flower pots. Check rain gutters and drains. Empty water from saucers under pots and water-holding plants such as bromeliads, and regularly change the water in root plant cuttings (both indoors and outdoors). Change water and scrub wading pools, birdbaths, and pet bowls at least weekly.

How residents can protect themselves from mosquito bites:?

  • Apply Insect Repellent. Use a repellent with DEET (N, N-diethyl-m-toluamide), picaridin (KBR 3023), oil of lemon eucalyptus [p-methane 3, 8-diol (PMD)] or IR3535 according to the instructions on the product label. DEET products should not be used on infants under two months of age and should be used in concentrations of 30% or less on older children. Lemon eucalyptus oil should not be used on children under three years of age. ?
  • Install or Repair Screens. Keep mosquitoes out with tight-fitting screens on all windows and doors. ?
  • Be Aware of the Peak Hours for Mosquitoes. Be aware of day-time biting mosquitoes and report them to the District, as these could be Aedes aegypti. Also be aware of mosquitoes that can transmit West Nile and Saint Louis encephalitis viruses. These mosquitoes typically bite at dawn and dusk. ?
  • Clothing Can Help Reduce Mosquito Bites. Wear long-sleeves, long pants, and socks when outdoors to help keep mosquitoes away from skin.
