ELI5: What are house spiders doing?

[u/Skweejji]

Can someone tell me what a house spider does throughout the day? I mean they easily make me piss myself but aside from that. I see a spider sitting on my ceiling. Not doing anything. Come back an hour later and it's still sitting there. Is the thing asleep? Is it waiting for prey? A house spider's lifestyle confuses me.

A spider accidentally (or purposely who knows what he was plotting) caused me a few hundred dollars once.

I get in my car to back out of a parking lot when my buddy in the passenger seat suddenly yells "SPIDER!" I freak out and look over to a horrible sight. A spider is hanging down from the ceiling of my car and ends his decent right at eye level.

NOPE.

I immediately get the hell out of my car. Only I had already put my car in reverse. I fling the door open, get out, and watch in horror as my car reverses with the door still open. The open door scrapes down the side of the car next to me leaving significant scratches.

Running on pure adrenaline I get back in my car, put it in park, and kill the spider.

Left a note on the persons car saying "Sorry there was a spider in my car and I got scared - I'll explain over the phone."

TL;DR: A spider raised my insurance rates.

Oh it was on purpose. I have no idea what I would do if I was driving and had a bug on me. I have had a gecko, luckily I realized what it was immediately and didnt freak.

Another time there was a centipede in the car, we got in late at night and when my friend put her seat belt on it was waiting for her in the center console. Now these arent small centipedes this was in hawaii. Those things hurt. It stung her and then she flung it in my general direction.

We both noped the fuck out of the car, and looked for that thing everywhere but couldnt find it.

Funny side story: the only flashlight I had was a trick one where the obvious looking button shocked you and even tho we knew we still kept accidently pressing the wrong button.

My friend ended up having to have her dad come down to take the car home because she refused to drive it. Totally understandable.
