Is there a Mod that makes Skull Trap work better?

I have had many instances where I set skull traps in the path on enemies, just to have them walk past them (literally right through them) without setting them off.
I had one not go off in a path I needed to take. So I had a summons walk right up to the trap without it going off. I had to march in circles around the trap before it triggered.

Is there a mod that makes skull traps actually go off when someone gets within 20' like the description says?
