Zombies act in a predictable manner, making zombie destroying traps simple, for even the most unskilled amateur to assemble.
However a simple rule applies that most fail to follow, including some very experienced trap makers:
“There will always be another”
-Zombies travel in packs
-Multiple zombies entering a trap will quickly clog it
-A clogged trap is a useless trap
-Ensure your trap has a self cleaning mechanism
There are many stories of individuals building effective zombie destroying traps, only to discover that several bodies in, they have no means of disposal and now their deadly pit trap has simply become a squishy bridge to their doom.
