Edgy Rick recently did a great video on splumonkey farms for Wicker mains:

But I wanted to find an alternative that could be used in solo DST even if one is not playing as Wickerbottom. The method I came up with involves fences placed in a square, with one fence gate, and inside of this box the player stands. The box should be at least 12 x 12 fences, and inside of it, Houndius Shootiuses are placed. The box should be built away from mobs that can destroy it. Since shadow splumonkeys will not attack fences, if they are the only mob at the farm it will be OK. The more Houndii you use, the faster the monkeys die.
To start the farm up, it is quite simple; run out to splumonkey pods in the nightmare phase and get shadow splumonkeys to follow you, then run back to the fence square, go inside of it and shut the gate. Then let the Houndius Shootius do the rest.
Pros vs Edgy Rick's guide:
- can be created without being a Wickerbottom
- gathering drops is far less dangerous since Houndius Shootius will not attack the player unless provoked
- no need to waste uses of lazy forager / explorer to escape the trap and gather drops
- the only danger from enemies in the farm is from the splumonkies/shadow creatures following you (or other creatures you attracted)
Cons:
- can be considered very expensive depending on your playstyle (Houndius Shootius need the (Ancient Guardian & Ancient Fuelweaver) + Deerclops to be beaten once per turret unless the Deerclops drops are obtained from a Loot Stash)
- kills shadow splumonkies much slower since the turrets use single-target attacks
- the walls are much more vulnerable to damage from other mobs, but they are also cheaper (perhaps using end tables as walls would prevent this? i didn't test)
- more dangerous when entering farm since gate must be closed behind you
I have a short video showing how this works (the file is uploaded along with the post)
Note that the footage has been sped up by 8x (original length was ~1 minute to kill ~40 shadow splumonkies with 5 Houndius Shootius) and the farm was set up with godmode in an empty world.
Just thought I would share this since I found very few splumonkey farms in my research. Happy killing guys!
