The thresholds for fogging are set very conservatively at 10 or more Culex mosquitoes or 25 or more total mosquitoes per trap regardless of species.  The color coding makes it easier to see where our "hot spots" are.  Interestingly, they are fairly localized, meaning there is a breeding site nearby which, when we find and eliminate or treat it, should result in lower trap counts.  In general, the edges of Paonia have had some hot spots, while the middle is usually pretty good.  Hotchkiss seems similar in having more mosquitoes on the edge by the river and on some of the mesas but not much in town.  We are working on getting the data in map form for the rest of the district.
