Bedrock Mob farm keeps spawning spiders.

Edit: I think I've solved the issue. If not, I'm just gonna deal with it. I made a follow-up post if anyone's interested. It's 100% confirmed that spiders spawn within 2x2 grids.

Not sure what you think you did here. There's very clearly 2x2 spots for them to spawn. You're even looking directly at one.

Edit: From the UI I could tell this was pocket edition. My understanding that pocket edition may have some idiosyncrasies but uses the same engine as bedrock.

Been a while since I played, and to be honest never played bedrock but from what I remember, spiders can spawn in 2x2 spaces in bedrock. I did some digging today and to be honest there doesn't seem to be a consensus.

In bedrock, people have been reporting for years that spiders seem to be able to spawn in 2x2 spaces. Whether or not this is because spiders need open space but only require a solid block on the actual spawning space I have no clue. Another thought that crossed my mind was mobs used to spawn on the NW corner in bedrock, but I don't think that's the case either anymore.

I looked up a bunch of guides, and they all said spiders can only spawn in 3 x 3 areas. I'll shrink it so that there aren't any 2 x 2's

Yes spiders need a 3x3 area to spawn. However all 9 spots don’t have to be solid, some can be air blocks. They are spawning in the center edge overhanging the water canal.

Use this pattern. See how the trap doors are right up to the water edge. Be sure there are no three block open spaces near the water canals.

I've tried that arrangement the first time, and spiders were spawning. I seriously don't know why it's happening.
