Method to Prevent Insect Spawn Inside of Base?

[LiQuiD0v3rkiLL]

Title says it all - I've searched this forum and Reddit for an answer to this. A wolf spider is able to directly spawn inside of our base, after we believed we had prevented it by building on top of the spawn.

Is it the Wolf Spider on the outside or under the Oak Tree? Or some other place?

I have a similar thing with The Infected Wolf under the Oak Tree.

I currently use structures to modify its pathing (block all but ONE entrance to the Oak Tree); its impossible to trap bugs currently (as of this post) because the game just moves the pathing but you CAN kinda modify it slightly....

....also as long as I dont aggro it, it wont jump up at me but AGGRO it and you have quite the scene
