Used reasonable human scent control such as a clean clothing and body each morning, rubber gloves and boots at or near sets, a canvas/rubber coated kneeling cloth at the set, avoided brushing up against trees, weeds, etc, wore a sweat band when necessary, picked group set locations from a distance to avoid tracking all over the set area, made sets quickly directly in and out and started early in the morning to avoid setting traps past noon or so. Those who didn't practice this detail never did well on a coyote line in July! The Mother coyote would move her liter at the drop of a hat, every detail had to be adhered to. In my opinion, canine trappers would do well to practice this standard in any season. I have observed over and over again that those who do always trap at a maximum harvest. Ace
