Everyone seems to have an answer until someone else jumps in saying they tried the same thing and it didn't work. The other day I was able to pinpoint an exact spawn location because the monster was clipped inside one of my stone walls and couldn't move. It was on flooring, with hoed ground underneath that, with roof above it, and well within the range of a covered workbench. So...

Anyone find any other tricks that worked for them that aren't the ones listed above? Because either the system is bugged, or none of those are actual spawn inhibitors.

I'm honestly about to just move to deep north or some other unfinished biome. This is driving me nuts.

I have responded elsewhere on this but here I go again. Workbenches (and I do mean those early workbenches, not forges or stonecutters or the the like, DO in fact stop spawning inside a base. The rule you MUST use is to make sure that you have multiple benches that overlap. The coverage area of a workbench is a circle as marked when you try to build something while standing inside that workbench build area. If you leave even a small area uncovered be any workbench, some WILL spawn in that tiny area. I mean that an area just the size of say a boar in game will likely spawn creatures of whatever variety that biome has to spawn. Also, make sure you have walls around your base. This is a given but many people think that creatures will not wander into the areas covered by the workbenches. This is not true. Workbenches only prevent spawning not wandering. My strategy is generally to place workbenches along the inside of my walls and then strategically throughout the base. Since I have done this and paid close attention as to the work area overlap of all those benches, I have not had one single creature spawn inside my base. I did remove a bench one time and forgot to replace it after a minor remodeling and creatures did spawn only in the area not covered. Once I saw it happen, I replaced the bench and no spawning has taken place since. I am talking about some 100 hours plus of play time here. Workbenches are your answer.
