How to Make a Creeper Farm in Minecraft

Gunpowder is one of the most useful mob drops in Minecraft. It fuels TNT, firework rockets for elytra flight and splash potions. A dedicated creeper farm filters out every other hostile mob so only creepers spawn and die, giving you stacks of gunpowder per hour with zero effort. This guide covers the trapdoor filtering method, cat-based mob funneling and two kill chamber designs.

Why creepers need a special farm

General mob farms produce zombies, skeletons, spiders and creepers mixed together. Spiders clog the system because they are wider than one block, and sorting drops from four mob types is messy. A creeper farm uses two tricks to guarantee only creepers spawn:

• Trapdoor ceilings, creepers are 1.7 blocks tall. By placing open trapdoors on the underside of a ceiling two blocks above the floor, the effective headroom becomes 1.5 blocks. Creepers can spawn in this space because the game checks the block height (2), not the trapdoor. Skeletons and zombies (1.95 blocks tall) cannot spawn in the reduced headroom. Spiders need a 2x2 floor space, limit the spawning platform width to single-block channels and they cannot spawn either.
• Slabs and buttons, place buttons or carpet on every other block to prevent spider spawning on wider platforms. Alternatively, use bottom slabs on the floor edges where spiders would try to fit.

Choosing a location

Hostile mobs spawn in dark areas within 128 blocks of the player and despawn beyond that radius. For maximum rates, build the farm in the sky (y = 200+) over an ocean. The ocean surface has no caves or land where mobs could spawn and steal mob cap slots. If you cannot build over an ocean, light up all caves within 128 blocks of the AFK spot. Every zombie spawning in a cave is one fewer creeper in your farm.

Spawning platform design

Build four to eight spawning layers, each separated by three blocks vertically (floor, two air, trapdoor ceiling). Each layer is a flat platform with water channels that push mobs toward a central drop shaft. Dimensions of 17 x 17 per layer work well and stay within spawn range when the AFK spot is directly above or below the center.

Construction steps for each layer:

• Place a solid floor out of any full block. Smooth stone or deepslate works.
• Leave a two-block air gap above the floor.
• On the ceiling (third block up), attach open trapdoors to every block on the underside. This creates the height filter.
• Carve water channels in the floor that flow toward the center. Use signs or open fence gates to hold water in place at the channel edges. Water pushes spawned creepers into a 2x2 hole in the middle of each platform.

Using cats to push creepers

Creepers are afraid of cats (tamed ocelots or stray cats). Place cats on leads tied to fence posts at the corners of each spawning platform, opposite the drop hole. Creepers that spawn near a cat immediately flee in the other direction, toward the water and into the drop shaft. This dramatically speeds up the farm by preventing idle creepers standing in dark corners.

You need one to two cats per platform, positioned so their scare radius covers the entire floor. Cats do not despawn once tamed, so they stay in place permanently. Name-tag them for extra safety.

Kill chamber options

All platforms funnel creepers into a central vertical shaft. At the bottom, choose one of these kill methods:

Fall damage (simplest)

Make the drop shaft 24 blocks tall. A 24-block fall leaves creepers at half a heart, and a single punch kills them. This approach gives you XP and lets Looting III on a sword increase gunpowder drops. Place a slab at the bottom with hoppers underneath leading to chests.

Campfire kill (fully automatic)

Reduce the fall to 22 blocks so creepers survive with a bit more health, then place campfires at the landing zone. Campfires deal one damage per tick and count as environmental kills, so drops flow into hoppers below the campfires without player interaction. This version works while you are AFK.

Entity cramming

Funnel creepers into a 1x1 space with a minecart in it. When more than 24 entities occupy the same block, they take suffocation damage. This method is slower but requires no fall height.

Rates and optimization

A well-built four-layer farm over an ocean produces 1,000 to 2,000 gunpowder per hour on Java Edition. Bedrock rates are lower due to different mob cap rules. To improve rates:

• Add more layers (up to eight).
• Light up every cave in the 128-block sphere around your AFK spot.
• AFK at the correct height, place your AFK platform 24 blocks above the top spawning layer so all layers stay within spawning range.
• Use a looting sword on the fall-damage design for 30% more gunpowder per creeper.
