How to Trap a Zombie

It's quite easy to trap a Zombie.  Zombies are stupid.  They follow some primal dead instinct to pursue a food source and consume it.  Zombies don't hunt.  Zombies don't stalk.  Zombies don't ambush.  They simply take a direct path to follow food and eat it.  For survivors, this is a tremendous advantage.  All you have to do is lead a Zombie into a trap that you can easily escape and spring the trap.

Examples of Zombie Traps

Zombie Barn Trap.  A classic example of a Zombie trap might be a barn.  You could run into a barn through an open front door, close the back door behind you and then circle back around to close the front door and trap the Zombie.

Early in The Walking Dead series, Herschel Greene kept his Zombie neighbors in his barn in hopes that a cure for the infection would have been found.

Zombie Pit Trap.  Another classic example of a Zombie trap would be a pit trap.  You could run from a Zombie, leap a covered pit trap, and watch the Zombie fall right in.  If there is ever a Zombie apocalypse, you will see that Zombies regularly fall into wells, pits, rivers, etc.  During the Vietnam War, the Vietcong guerillas and North Vietnamese set up all sorts of well hidden pit traps that were filled with spikes.

Zombie Spike Trap.  Since Zombies don't feel pain, they can also be lead to impale themselves.  The earth works at the Yorktown Battlefield in Virginia (photo below) provide an example of wooden spikes set to deter a charging enemy.  If the spikes were sharp enough, they might simply impale an unfeeling Zombie.

In Season 3 of The Walking Dead, a crazed and grief-stricken Morgan Jones makes good use spike traps to impale Zombies in his community so that he can kill them and release them from their wandering.

The key to trapping Zombies is to use your live, human, brain to outwit the Zombies and lure them into a situation that they simply cannot escape.  They'd do the same to your if they could just get one bite!
