LARIMER COUNTY - In an unprecedented move, Larimer County ignored Fort Collins city policy and sprayed for mosquitoes Friday in the city's southeast corner, where repeated samples recently tested positive for West Nile virus.
Larimer County commissioners on Tuesday supported the county health department's recommendation to overstep the city's spraying guidelines. The health department gave the same recommendation to the Larimer County Board of Health, which makes the decision on spraying and was waiting for the commissioners' blessing before moving forward.
The county has not sprayed for mosquitoes within city limits for more than 25 years.
In order to spray an area for mosquitoes, the city of Fort Collins requires two human cases of West Nile to be reported within a 7-day period while the vector index, a measurement of the amount of West Nile-infected mosquitoes, must come in at a level of .75.
The county will spray again on Monday.
