Mosquito spraying takes place tonight in Craig and areas of Moffat County. Moffat County Pest Management usually treats the two areas separately, but have decided to do both at the same time this year. That means there will be two planes in the air tonight making chemical drops. While the chemicals are believed to be safe for humans and animals, experts recommend bringing children and pets indoors while the spraying is taking place. The treatments will take place in the evening hours.
