barbed wire is a bear to move/install.
straight wooden frames with wooden panels on them placed so that you block line-of sight to where you see the zanimals come from the most can really cut down the numbers as they seem to rely mostly on vision. its cheaper than walls plus you can drag/drive these things around.
skewers for self-defense. zombears and zolves are afraid of fire, so you could prepare the ground and dance around a fire throwing stuff at them. dogs not so much. but they do burn too. just wear something tanky around the house and meeat them over a nice hot fire.

just thought i’d give this another go[/quote]
Hmm, maybe some attached flamethrowers on frames would do well for base defense? They require the non-craftable flamethrowers as far as I can tell though. Still, if you make a choke point, it could work I suppose.
