City of Laramie Mosquito Control has scheduled the aerial application of Dibrom for control of adult mosquitoes in rural areas adjacent to the City on Tuesday evening, July 8th beginning at 7 pm. This application is targeted to control both nuisance and vector mosquitoes, including Culex tarsalis, which can transmit West Nile virus (WNv). Currently vector mosquito numbers are low in the City but are increasing in rural areas. Migration of these vector mosquitoes into the City is likely if left uncontrolled. The aerial application will be conducted during the evening hours to coordinate with the peak of mosquito activity and to reduce the likelihood of contact with citizens’ work and recreational activities. The aircraft contracted to provide the application service is equipped with special night operations equipment and much of the application will take place after dark.
Three areas are scheduled for treatment: southwest of the city limits along Highway 230 and the Big Laramie River drainage from the city limits southwest approximately 9 miles; west of the city limits between the Big Laramie River on the south, Interstate 80 on the north and the Laramie Regional Airport on the west; the third area is north of the city limits between Welsh Lane and 45th Street including the area of the City Wastewater Treatment Plant and the City Landfill.
Dibrom will be applied at the ultra-low volume rate of 1/2 ounce per acre. No application will be made within the city limits. The application will be rescheduled to take place on Wednesday morning, July 9th at 4:30 am or Thursday evening, July 10th at 7 pm if bad weather prevents the Tuesday, July 8th application.
Presently no cases of West Nile virus (WNv) have been confirmed in Albany County and the City of Laramie currently rates the risk of infection at level 1 (Low Risk).
