Where do black widow spiders hide in the house

I live in los angeles california and i am pretty worried about this spider please help

They like dark undisturbed areas like say, under a staircase. They don't tend to live "inside" houses because even vibration annoys them. The like it dark, cool and quite...

I wouldn't worry too much about being bitten if you live in a metropolis as big as L.A. If you live a little more rural like in say "Backwater-Alabama" you'd be more likely to come across this spider...

In dark damp warm places

they hide in your shoes.

pillow cases...lol
i'm kidding...i don't know.
