Mosquito control application scheduled in Murrieta on Wednesday morning


Due to recent positive West Nile virus mosquito test sample results, the Riverside County Vector Control Program has scheduled an ultra-low volume ground application using truck-mounted sprayers to reduce the number of adult mosquitoes.

The application of EPA approved mosquito control product Zenivex (EPA Reg No 2724-807) is scheduled for Wednesday (Sept. 16) from 5 a.m. until 7 a.m.

The treatment will occur in Murrieta. The area, across from Calvary Murrieta Christian School, is 4.5 acres. This location is bordered by Jackson Avenue to the northeast, California Oaks Road to the east, and Monroe Avenue to the southwest. 

The product used is registered by the Environmental Protection Agency (EPA) for the purpose of controlling mosquitoes and protecting public health. The product is applied according to label instructions by trained and certified technicians. Although the product poses very low to no risk, some people may prefer to avoid exposure. To minimize exposure, residents and pets should remain indoors and keep windows closed during and for 15 minutes following ground application. The amount of material sprayed is three ounces per acre, which ensures that humans, animals and crops are safe.  Signs will be posted Monday (Sept. 14) along the route informing residents of the control efforts. 

In addition, vector control staff are intensifying mosquito surveillance, searching out breeding sites, and conducting larval control where appropriate.

Protect yourself 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 percent or less on older children. Lemon eucalyptus oil should not be used on children under three years of age.
  • Be aware of peak mosquito hours. Dawn and dusk are peak biting times for many mosquitoes. If mosquitoes are biting during the daytime hours, please mention that when calling the Environmental Health office as it will help identify the species of mosquito in the area.
  • Clothing can help reduce mosquito bites. Wear long sleeves, long pants, and socks when outdoors to help keep mosquitoes away from the skin.
  • Mosquito-proof your home. Drain standing water. Mosquitoes lay their eggs in standing water. Limit the number of places for mosquitoes to breed by draining or discarding items that hold water. Check rain gutters and drains. Empty and scrub out any unused flowerpots and wading pools. Change water in birdbaths, livestock troughs, and pet bowls at least weekly, scrubbing thoroughly before refilling.
  • Install or repair screens. Keep mosquitoes outside by having tightly-fitting screens on all of your windows and doors.
