Loveland is shifting into mosquito-fighting mode this week, rolling out targeted spraying in select neighborhoods as officials try to keep West Nile virus at bay. Instead of fogging the entire city, crews will focus on small, higher-risk pockets identified through trap surveillance. Residents can expect to see spray trucks in the evening and get more precise, block-level alerts about which streets are on the schedule.
Local broadcaster CBS News Colorado reports the city confirmed the plan in a short advisory and said crews will concentrate on neighborhoods where surveillance has shown elevated mosquito activity. According to CBS News Colorado, the effort is part of Loveland’s seasonal mosquito-management work.
How officials decide where and when to spray
The City of Loveland contracts with Vector Disease Control International to run seasonal surveillance and testing across roughly 40 trap sites, then deploy treatments when certain thresholds are met. Fog-spraying is triggered only after trap counts or infection data cross set levels, with the city citing a benchmark of about 100 total mosquitoes or 50 Culex mosquitoes in a single trap. Adult mosquito treatments are paired with larvicide work and public outreach, and the city posts maps and program details for residents to review, according to the City of Loveland.
