A deadfall is one of the simplest and most effective animal traps. It is simply a heavy weight, such as a rock or log, that is suspended over bait attached to a trigger. When an animal tries to eat the bait, it will spring the trap and the weight will fall, killing the animal.
Snares are also very effective traps in their simplest form, although they can take many shapes and complex designs. The most common type of snare is a thin piece of looped wire that is attached to a power mechanism, such as a bent sapling, that will spring when an animal disturbs the wire. As the loaded sapling snaps back, the wire is pulled tight around the animal's neck. Used correctly, this trap is a humane way of taking game, though to be effective it should be placed across a known animal trail.
Spears and Projectiles
Among the most complicated forms of animal traps are spears and projectiles. These traps consist of a short sharpened stick placed under load by a bent sapling or bow. A wire is placed across an animal run, and when it is disturbed, the spear is released and driven into the animal. Although this method is very complicated and less successful than simpler designs, spears can be made to take larger game than snares or deadfalls.
