Are you [REDACTED] kidding!? Ofcourse they're planning something!!
You've said you have a messy home, don't clean often, don't wash used dishes and cutlery and now above all that you've made a truce with spiders living in your home, so now you're not hunting them down?
You've pretty much created the perfect habitat for them!
The only thing that I spider could want more than that, is maybe food, as I'm not shure if spiders can/will eat food rests from unwashed dished. But, don't worry, I'm shure they'll figure something out for that!
So, hell yeah, they're planning something! They're gonna have babies!
Mommy spider is undoubtedly making a little nest somewhere in your warm and cozy cave, and within no time, you'll have a huge bunch of cute tiny little baby spiders running around!
Shure, they're going to be friendly to you, as you've been soo kind as to give them shelter, as well as not hunt them down, and as creature that is capable of killing them, pretty much effortlessly.
But, I'm a little confused tho, I thought you said you wanted to be a crazy cat-lady, when you got older, and not future
SCP-2269? :\
Ok, all kidding and somewhat (non ill-tempered) cynical scare aside, though...
Maybe it's better if you start doing something about this
now rather than later, as I'm shure that you don't actually appreciate having spiders in your home?
Like, try getting any and all spiders you see straight out the door.
Don't kill them! That makes food for other spiders and spider-food do eat and thrive on. Just gently pick them up with a dustpan, (wear heavy gloves if they really freak you out) and put them outside.
Whilst there are no spiders to take outside, you might want to tidy up the place to make shure that there aren't any nests, or webs anywhere. If you've found a nest, just whip out vacuum cleaner and get rid of it. (You don't have to worry about your vacuum cleaner becoming a spider-spawning device, that's not gonna happen)
And, if you really want to keep the spiders out, you should remove any of their food sources, or even their food's food sources, like unwashed dishes, and stuff like that.
Plenty of internet guides for it, too...And, again, if you really don't want your home to be a spider haven, you should start working on it sooner, rather than later.
I've heard "Rentokill" doesn't come cheap...
