City of Laramie Mosquito Control Fogging Concluded
The rating of the Risk of West Nile virus (WNv) infection continues to be rated at LEVEL 1 (LOW RISK) based on the Centers for Disease Control (CDC) guidelines for a phased response to WNv surveillance data. Currently four samples have tested positive for WNv in Albany County. 

Surveillance traps located throughout the Laramie Valley are showing low counts of vector mosquitoes. Although the trap numbers have dipped below the treatment threshold there is still a slight risk of infection through mosquito bites and citizens are reminded to continue to use precautions, especially from dusk to 10pm, when vector mosquitoes are most active. 

On August 22nd, fogging for the control of adult mosquitoes was suspended pending the results of further surveillance. On September 5th, a special treatment was done in the West zone to target vector mosquitos after a mosquito sample from a trap adjacent to the west zone tested positive for WNv. There has been no increase in adult activity signaling that most of the blood feeding activity has ceased for the season. Based on this assessment, all fogging has been concluded for the season. 

 Larval control operations will continue at sites where permanent water may produce more vector mosquitoes. During the late summer/early fall, female mosquitoes cease blood feeding and feed exclusively on nectar to prepare for winter hibernation. The mated females will overwinter in warm places and take a blood meal in the spring to begin the next generation of offspring. By continuing to do larval control we can help to deplete the numbers of overwintering females that will be available to start next year’s production. Larval control crews will continue treatments until freezing conditions eliminate larval activity. 

City of Laramie technicians have tested a total of ninety-nine (99) samples of Culex tarsalis mosquitoes throughout the summer season with four (4) samples testing positive for WNv. Further Wyoming WNv information can be found on line at: the or the Centers for Disease Control website: information regarding chemical applications on City owned properties will be updated daily at 4pm. Call 721-5056 or click on the Mosquito and Chemical Application hotline tab on the City of Laramie home page. For further information contact Tyler Shevling, Mosquito Control Crew Supervisor at 721-5258 or Scott Hunter, Parks Manager at 721-5257.
