Protect Yourself with the Four D's!
- Drain: Mosquitoes breed in water! Drain any standing water in your yard each week. Bird baths, clogged gutters, and kiddie pools are common breeding sites.
- Dress: Wear lightweight, long-sleeved shirts and long pants while outdoors. Spray clothing with insect repellent since mosquitoes may bite through clothing.
- Defend: Apply insect repellent sparingly to exposed skin. Use an approved repellent according to its label. Find the repellent that is right for you.
- Dawn/Dusk: Limit time spent outdoors at dusk through dawn, when mosquitoes are most active and feeding.
Weekly Vector Index
The City of Fort Collins tracks measures (in four separate zones) to assist in the determination to spray for adult mosquitoes. In addition to a recommendation by Larimer County, prior to commencing adulticide treatment, the incidence of human WNV infection must be confirmed in the City. Confirmation will occur with evidence suggesting Culex mosquito populations are increasing at or above historical levels, in which case spraying will commence in any treatment zone where the vector index meets or exceeds .75
WNV vector index levels updated weekly. Last updated: August 6, 2018.
VECTOR INDEX:
NW Zone: 0.18
NE Zone: 0.06
SE Zone: 0.19
SW Zone: 0.05
