The Larimer County Health Department said it continues to see a high number of mosquitoes that carry the West Nile virus.

“We try not to spray, that’s really our stance. We use it as a last resort and we’re lucky that the City of Fort Collins does a lot of preventative work every year and usually that covers our season. Some years are worse than others,” said Larimer County Department of Health spokeswoman Katie O’Donnell.
