Only you can prevent West Nile virus

Recent tests show the virus has arrived across Boulder County

By Mollie Putzig

With a backpack full of specialized bacteria, a force of technicians patrols Boulder-area still waters for miniature pests that can metamorphose into airborne vectors of disease. Acting like the Ghostbusters for mosquitoes, technicians seek out larvae and douse them with a spray of tiny bacteria called Bti — Bacillus thuringiensis israelenis. Bti is derived from naturally occurring soil bacteria and act as a larvicide that kills infantile mosquitoes before they can emerge from their watery breeding grounds.
