What Blocks Can Spiders Not Climb in Minecraft?

Spiders are arthropod-neutral mobs with 8 legs, 16 health points, and 2-4 attack damage.

With the flexibility to change the behavior between passive and hostile based on the light level, spiders are quite dangerous in some cases!

Not like other hostile mobs, spiders are unique because of their climbing ability. They can climb on any surface and height to reach and attack you. With that being said, knowing what blocks spiders cannot climb in Minecraft is crucial!

We all know that spiders can climb dirt, stone, or cobblestones. Those blocks have one thing in common. They’re solid. Another scenario to answer the question is: if the player can walk through a block, spiders can climb on it too!

But spiders can’t climb all solid blocks in Minecraft! Even though the block is full, there are some exceptions!

Below are blocks that spiders can’t climb:

  • Signs (any wood type)
  • Grass (including tall grass, fern, and seagrass)
  • Sugar cane
  • Flowers
  • Fire
  • Water (but spiders can be pushed by water like other mobs)
  • Portal blocks
  • Soul Sand

Besides the blocks above, honey blocks are also a good source to partially prevent spiders. They do not block the spiders but will slow them down.

On another hand, spiders can climb transparent blocks like fences, fence gates, glass panes, or iron bars. But if only you place them in a straight column.

Some transparent blocks spiders can climb:

  • Fences (any wood type)
  • Fence gates (any wood type)
  • Glass pane
  • Iron bars
  • Ladder
  • Vines
  • Cactus (spiders will take damage)
  • Ice (including packed ice and blue ice)

If your wall is made of alternative rows between the full block and transparent blocks above, spiders can’t climb because of the width difference.

Another useful tip if you don’t want to fix your wall is to build a ledge on top of your wall. This will prevent the spiders from climbing all the way up. But still, you will be hearing the spider noise all the time!

Happy farming, Minecrafters!
