What kind of spider makes a thin, wispy, wafty web indoors?

[dudsville]

I'm constantly taking down these billowing web things? No real structure or design to it, just stretches across a bit of upper wall and ceiling, in corners, etc. I never see the owner. Who is it????????

Those wispy daddy long legs type spiders make those type of webs. (And they eat the big fast-moving scary spiders, so I leave them be if I can.) Mind you, you usually see the owner with them, so if they're all dusty I assume the owner has moved on to another corner.

Cellar spiders, they do indeed eat the huge spiders so I let them stay.

I leave spiders be, but I don't leave webs.

I meant to say thank you! I will now google to see the webs of these spiders and confirm!
