How To Make a Mob Farm in Minecraft (Easy, Step-By-Step Mob Spawner)

Author:Kristen Update:Feb 27,2025

This guide provides a straightforward method for constructing a highly efficient mob farm in Minecraft. A mob farm is a crucial element for any successful Minecraft world, comparable in importance to farms and villager trading systems.

Step 1: Gather Resources

Begin by accumulating a substantial quantity of building blocks. Cobblestone and wood are readily accessible and ideal choices for this project.

Step 2: Ideal Spawner Location

Construct your mob farm high above ground level, preferably over water. This prevents ground-level mob spawning and ensures mobs are funneled into your farm. Build a small platform approximately 100 blocks high, adding ladders for convenient access. Place a chest and connect four hoppers to it, as illustrated.

Step 3: Construct the Main Tower

Build a 4x4 tower around the hoppers, extending it to 21 blocks for XP farming or 22 blocks for an automatic farm. Place slabs atop the hoppers.

Step 4: Create Water Trenches

Construct 7-block long, 2-block wide bridges on all four sides of the tower, building 2-block high walls around them. Place two water blocks at the end of each bridge to create a water-flow system.

Step 5: Complete the Structure

Connect the water trenches to form a large square. Ensure walls are at least two blocks high to prevent mob spawning outside the designated area. Complete the structure by adding walls, floor, and roof.

Step 6: Add Lighting and Slabs

Place torches or slabs on the roof to prevent mob spawning there. Once complete, wait until nightfall to observe the functioning farm.

Enhancements for Increased Efficiency

  • Nether Portal: Connect a Nether portal for easier access.
  • Pistons for Switching Modes: Use pistons and a lever to easily switch between XP farming (21 blocks) and automatic farming (22 blocks).
  • Bed Placement: Place a bed nearby to boost spawn rates.
  • Carpet Placement to Prevent Spider Spawning:
