Responses of free-roaming coyotes (Canis latrans) to four chemical attractants (W-U lure, artificial beef liver flavor, artificial smoked fish flavor, and Fatty Acid Scent) used on M-44 tops were measured during the summer months in Colorado, Idaho, Montana, Washington, and Wyoming. Visitation and pull rates varied throughout the study period from area to area and appeared to be associated with weather, food abundance, and coyote densities. Fatty Acid Scent and W-U lure produced the highest visitation and pull rates.
