Steel wolf traps, used frequently in the American west, were made from heavy steel, were six and a half inches wide, and had two springs, each with 100 lbs of power. Steel wolf traps were usually the same models used in the capture of beavers, lynx and wolverine. In order to hide the human scent, trappers would handle their equipment with gloves, and cover the traps in beeswax or blood. As the wolf's power of scent is so great, a mere touch of human skin on the trap will result in the wolf vacating the area. Wolves may also dig up or spring the traps. The traps would typically be set in fours around a bait and strongly fastened to concealed logs, and covered in moss, chaff, cotton or sand for camouflage. Sometimes, the trap and the bait would be placed in a pool of water, thus leaving no other point of access for the wolf to take.
