How to stop mobs from spawning in your house?

I stand corrected . Shows how often I play vanilla... it was upper slabs and upside down stairs. I'll just.... walk over here.... ::runs out the emergency exit::

Another thing you can try too is the Monster Spawn Highlighter mod. Super easy to mod into FTB and works like a charm. It's kind of an essential mod for me, even though I just use it once per base build.

Why didn't I know about this?! This will make lighting the caverns my turtles leave behind so much easier! Thanks a ton lol!

I'm kinda opposed to that since it requires clay. That stuff's more valuable than diamonds in my worlds. :/

I've found that skimming the bottom of deep water with a shovel, some dirt and torches (or doors), and a couple of night vision potions makes collecting clay pretty trivial overall.

Seriously people, use this mod. It can tell you exactly where mobs can spawn. It is very accurate since the way it can tell is that it simulates spawning and this way can adapt to new spawning mechanics without changing its own code.

Personally, I use Xycraft's blocks inside my house (I'm using the Magic World pack with Xycraft added since XycraftWorld is 1.4.5 but not 1.4.2). That makes mobs spawning inside my house impossible.

The Modular Force Field System has a defense block you can set up to automatically kill any mob that spawns in your base. It requires some power to keep it up, but with a healthy IC2 system or enough forcium you can keep it going pretty much indefinitely.

-It looks friggin awesome with connected textures and massive pipe/tube networks

It does indeed look friggin awesome.

Presumes Gregtech which is probably the most popular mod that people turn off. Hence me saying that clay is more valuable than diamonds in my world.

If you're unwilling to play with the config until you're happy you could install Plugins for Forestry, which adds a recipe to make clay with beeswax and sand, dirt or gravel. When Extra Bees is ready it's river bees produce clay.

Staying within the beta pack, red cobble from the mountain ridge biome can be crafted with water buckets for clay. Another recipe uses sludge gotten by processing ore through the Factorization grinder and then mixer.

Or just take a shovel to the nearest riverbed or swamp.

Half blocks still work to ward off monster spawns same as always. You just need to make sure that your using the lower half and not the upper half of them. Since now you can place both normal and upside down half blocks and the upper upside down ones act as normal blocks for everything including mob spawning. So if you want to block mob spawns you need to make your floors a half block lower then normal.

That is the problem Direwolf ran into. He built the room with a doubleslab floor.

I use Light Level Overlay myself. Gives a bit more info than just where mobs can spawn. However, the two mods have different features.

Another way to keep mobs from spawning is to used crushed obsidian as a floor. Mobs can't spawn on it. You can use the igneous extruder from TE to create the obsidian, then feed that to a Railcraft Rock Crusher. Unfortunately, crushed obsidian is affected by gravity, so you would will need 2 thick floors.
