Here at WBR Mosquito Control, our mission is to protect the citizens of West Baton Rouge Parish from the threat of mosquito-borne disease and to combat nuisance mosquito problems to improve the quality of life for everyone in our community. To achieve our mission, we operate on an IMP (integrated pest management) basis, meaning that we employ multiple science-based principles to control mosquitoes. These principles include; mosquito surveillance, disease testing, larval mosquito control, adult mosquito control, source reduction, resistance testing, and public education. Below, are details on how we use these methods in our day-to-day operations.  

  1. Ground ULV Spraying
  2. Ground Larviciding
  3. Source Reduction
  4. Mosquito Trapping and Testing
  5. Community Outreach
  6. Free Pesticide Products

On-Road ULV Applications

Ground-based Ultra-Low Volume (ULV) spray truck operations comprise the bulk of our pesticide-based tactics for the control of mosquitoes in WBR Parish. When and if we spray is based primarily on the weekly results of our disease and mosquito population surveillance program.

The pesticide products we use in our spray trucks are primarily water-based pyrethroid-type adulticides. All of the products we use at WBR Mosquito Control are approved by the Environmental Protection Agency, The Louisiana Department of Agriculture and Forestry, and The Louisiana Department of Environmental Quality for the control of insect pests. 

Our spray trucks typically spray either 1 to 4 hours after sunset or 1 to 4 hours before sunrise during mosquito season (March/April through October/November). There are multiple reasons for this including, it is scientifically proven that these are the two peak activity periods for mosquitoes, most beneficial insects (honey bees) are not impacted by the pesticide product, and weather conditions that can degrade the effectiveness of the spray (direct sunlight, wind, evaporation, lack of temperature inversion) are not present as they would be during daylight hours. 

Our spray trucks are all outfitted with GPS tracking and computerized spray machine control technology. Our spray trucks are calibrated to spray from 2 to 20mph. The spray machine control will not allow the trucks to spray while stationary and also will not allow the trucks to spray if the truck is traveling over 20mph. If you are concerned that one of our drivers has missed your street or area, call our office, give us a date and time and we can look the spray mission up on our computer to confirm whether our driver executed their spray mission properly.  

We would ask that when you see our trucks out spraying, please go inside for about 30 minutes. Our drivers are instructed to turn off the spray machine if people are standing by the road, walking, jogging, or bicycle riding towards them. They are instructed to travel approximately 100ft past the person or persons in proximity to the spray truck and then resume spraying. Although the products we use are safe for humans, pets, and plants when applied correctly, still they are pesticides and we do not recommend you run behind, play, or stand in the spray. Some of the products we use can be hazardous to some species of fish such as koi and goldfish if sprayed in direct proximity to them. For more information on spray truck policy and procedures, the pesticide products used, or to inquire about your area being sprayed or not, call our office at 225-214-5900.

Off-Road ULV Applications

Off road vehicle ULV sprayingOff-road ULV spraying is accomplished by the use of our Kawasaki SXS vehicles. These vehicles allow us to access areas that we could not safely or easily take a spray truck into.

We often use these vehicles to treat areas such as parish parks, areas behind the levee system, parish schools, and any other area that needs to be treated where we cannot take a spray truck into.

GIS Weekly Spray Zone MapGIS spray zone map image

Our GIS spray zone map is a tool to inform the public of when and where ULV spray truck operations are scheduled to take place. The map is divided into north, central, and southern "spray zones". These zones contain one or more mosquito trap locations which, when found to have large mosquito numbers or disease-positive samples activate spraying and other control measures within that particular zone. You can access the map on the home page of this website, by checking out our weekly updates on our WBR Mosquito Control FaceBook Page, or by clicking here. We also have a short how-to video on how the map works and how to use its functions. You can access that video here.
