FORT COLLINS, Colo. -- The air in northwest Fort Collins was temporarily filled with a mosquito-killing fog as a mosquito abatement crews worked to reduce the amount of bugs in that area this weekend.
Larimer County officials said the county typically ranks in the top 10 nationally for West Nile virus cases.
Officials said spraying for mosquitos is controversial, but necessary this year.
“Our risk index has gotten really high, we've seen an increase in human cases, so for us this is kind of last resort but we have to do it to try to protect our population," said Katie O’Donnell, spokesperson for Larimer County.
There is one thing you need to remember about West Nile, too, O’Donnell said.
“West Nile is preventable, that's what I tell people. Wear your bug spray. If everybody wore their bug spray, we wouldn't have these cases," said O’Donnell.
There are no more planned spray events currently scheduled, but O’Donnell said it’s likely there will be more before the end of the season.
