Eli5: what do spiders eat in bathrooms? Do they starve if nothing falls in their web?

I have always wondered why spiders prefer to make webs in bathroom corners and I somehow feel sorry for the little guys - I have never seen a fly or other insects in my bathroom and I can't help thinking my spider-bros will starve. Do they?

They’ll eventually ditch the web and try again elsewhere if there’s slim pickings in that spot.

You’ll know if they’ve been successful because they don’t eat the exoskeletons and so pieces of bug armor begin to collect beneath active webs.

They like humidity because the water helps keep the web material pulled tight.  It’s harder to keep a web taught when it’s very dry.

Some household bugs like silverfish are also attracted to moisture.
