Simple way to stop the spawning of caveworms.
How to Keep The Caveworms Away
How to Block Caveworm Spawning
- Step 1: Mine (at least) 200 stone.
- Step 2: Kill caveworm.
- Step 3: Attempt to place stone piles on top of caveworm spawnpoint.
- Step 4: Leave cave.
- Step 5: Enter cave to see if caveworm has been successfully blocked.
Not all spawn points will allow for this due to the terrain, and I haven’t tested this with anything else, but at least it’s cheaper than an electric dehumidifier!
