I'm covering everywhere near my house with my torches and building walls (using fences or blocks) around them, to make sure no creepers blow me up as I come out, or trample my sugar cane and wood. (I have now completed about 80% — without using any mods, tools, or other cheats.)


However, as you can see, the tops of some trees are too dark. So I'm worried about monsters spawning on the top of trees. There's some mention about leaves and mobs in Minecraft Wiki:

...and they never spawn on Glass, Ice, Stone Slabs, or other see-through or non-cube blocks.

(I'm playing Minecraft in fancy mode.) Even if monsters can't spawn on the leaves, maybe some monster can spawn on the wood that's not covered by leaves.

(Don't mention about spiders -- since they can climb fences as you know and I don't care about them)

Can monsters exist near my house?

The distance between my torches is 5 metres.

    I've had creepers dive bomb me from tree tops. That was fun.

  • I saw creeper on top of the tree, but I couldn't sure whether creeper spawn on the tree or just climbed up there... so I'm asking now. Yeah... It would be funny if creeper dove from tree and exploded...

    I think that it would be a better idea to have the older material be updated rather than separate information out between two different questions. I can start up a bounty on the older question asking for confirmation that this still applies as of recent updates for you, if you want.

    @nicky - you can't do paragraphs in comments. If you need to add a lot of information just edit your question.

Update: According to Notch's blog post about changes coming in 1.6, the torches-on-fast-leaves bug is getting fixed:

  • Fixed buttons and levers being placeable on leaves in “fast graphics” mode

This means that monsters can no longer spawn on leaves, either, as they are always considered transparent, even when using Fast graphics.

Monsters can spawn on any solid, non-transparent block which is at light level 7 or lower.

Signs, torches, rails, and the like are ignored when spawning monsters; they'll spawn on the block underneath just fine. This is why one-block-wide railways need to be lit.

Transparency means whether or not light passes through a block rather than whether you can see through it. Half-blocks, doors, stairs, and glass all count as transparent and prevent monster spawning. Leaves, oddly, count as transparent only when Fancy graphics are enabled. An easy way to test a block for transparency is to try placing a torch or sign on it — neither can be placed on transparent blocks. (Meaning that torches can be placed on leaves with Fast graphics, but not with Fancy.)

Torches put out light level 14, so monsters can't spawn within 5 blocks of a torch orthogonally or 3 blocks diagonally. If you put your torches in a diamond pattern, they can be up to 9 blocks apart, but it's best to move them closer than that on uneven terrain. (I use 5 myself.)

If you like, you can actually torch your treetops by changing your graphics to Fast, placing the torches, and switching back. Your torches will stay rooted, even though you wouldn't normally be able to place them that way. Personally, I think it makes them look rather cheerful. :-)

    Note that in multiplayer, you can place torches on leaves with Fancy graphics. I've also seen monsters spawn on treetops at night and catch fire the following morning, in multiplayer. Commented May 15, 2011 at 17:02
  • I thought it was light level 7 or lower? Did you find documentation on 6? I've also always been able to place torches on trees independent of my graphics settings, both single player and multiplayer... Commented May 21, 2011 at 22:56
  • @EdGruberman — You're right, it should be 7 — fixed. You should not be able to place torches on leaves in unmodded SSP when Fancy graphics are enabled. I've always played on Fancy and didn't realize that you could ever place torches on leaves until I happened to be reading the source code for the leaf block one day. :-)

I created a test world in MCEdit consisting of 40x40 chunks (640x640 blocks) and filled it with a layer of leaves.

I then loaded the world into Minecraft 1.8.1, set the difficulty to Normal and the graphics to Fancy, and waited until nightfall:

Sunset over a field of leaves

Once nightfall hit, I found no mobs anywhere:

Night over a field of leaves on Fancy

This corresponds to what the old behavior was. However, when I switched over to Fast graphics, I found nothing as well:

Night over a field of laves on Fast

So I decided to dig a hole to act as a control:

Hole in the leaves

And sure enough, the mobs started spawning once I moved 24 blocks away:


My, that's a very nice test world you have there. It'd be a shame if someone were to...blow it up. Again, this is still on Fast graphics. For good measure, I looked away from the mob hole, and again, found zero mobs spawning:

No mobs!

So in conclusion, no, hostile mobs cannot spawn on leaves—regardless of your graphics settings—in Minecraft Beta 1.8.1.

If you'd like to test this yourself, you can download my test world.


Monsters cannot spawn on top of leaves. It says in the official handbook that they can only spawn on solid blocks, not transparent blocks or slabs. You do not have to worry about mobs spawning on top of trees. Since leaves are cheaper than glass, you can easily mob proof large areas with leaves for not much price. But torches would still be cheaper. Slimes can spawn in lit areas, so if you want to slime proof an area use leaves. You are asking if mobs will exist near your house, they cannot spawn there, but they can spawn somewhere else and walk there.
