Mosquito Control Applications Scheduled for Perris on Thursday

Riverside County News Release

Due to the extremely high activity of West Nile virus, the Riverside County Vector Control Program has scheduled ultra-low volume (ULV) ground applications, using truck mounted sprayers. This treatment is aimed at reducing the risk of disease transmission to humans and animals by reducing the number of adult mosquitoes in a neighborhood.  The treatment will occur at the highlighted areas in the city of Perris shown on the map below.

The application of EPA approved mosquito control product Zenivex (EPA Reg No 2724-807)  is scheduled for Thursday between 5:30 a.m. and 7 a.m.

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

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

We would like to remind residents to look for and eliminate areas of standing water on their property following the recent rains.

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% 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 you are experiencing mosquito bites during the day- please mention that when you call our office as it helps us to identify what species of mosquito might be in your area.
  • Clothing Can Help Reduce Mosquito Bites. Wear long-sleeves, long pants, and socks when outdoors to help keep mosquitoes away from 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/discarding items that hold water. Check rain gutters and drains. Empty unused flowerpots and wading pools. Change water in birdbaths, livestock troughs and pet bowls at least weekly.
  • Install or Repair Screens. Keep mosquitoes outside by having tightly-fitting screens on all of your windows and doors.
