my earlier post- my traps and stuff are designed for humans. if zombies get stuck in them or injured by them, well, they'll be immobile or extremely easy targets for me to shoot. i think many will die from the traps, eventually, they'll be stuck there for all eternity unti lthe sun bakes their bodies dry and they fall apart. punji stake type features steel spikes in an deep earthen pit. if it gets a bit full i can pour some flammables on the pile of wriggling bodies and see if fire and deal with that. evtually it'll be full of decomposing zombies which I'll just put some earth on that and put a concrete pad on that. the pad will feature steel poles at least 10 feet high about 1 foot apart pointing outwards at a 35-45 degree angle. other steel bars would be welded to those poles to create a climb resistant fence of shinning stainless steel, effective against humans and zombies. then i might bolt some horizontal wooden stakes to the vertical parts, pointing outwards, so zombies will press up against them and the force of the mob will force the first half dozen zombies to be impales by it.
