Please help me ASAP

Ok so I was rereading false memories, finished it, looked to my right (my eyesight was blurry from reading manga so long), saw a blurry big black thing, turned on the light and blinked a few times, and it was a huge spider . Its diameter was half the length of my pinky. It went onto my ceiling and fell off, so I sprayed it with windex and it eventually died. ╥﹏╥

So, I’ve been seeing a lot of spiders in my room and I literally have no idea what to do. I’m terrified to death of them, and yes, I’ve heard the argument “they’re small and scared of you so why are you scared of them” well you no wat a knife is smaller than me and knives are scary too.

TLDR; I looked up how to get rid of spider infestation but like I don’t think I have cracks in my room or anything like that, so what should I do? Does anyone know any good spider killer method or a way to tell for sure you have an infestation? Or a way to kill spiders from a distance bc I’m too scared to do it the old fashioned way where you take toiler paper n squash it bc the feeling of squash spider is terrifying. Thanks y’all.

Also I am not open to putting a spider on a piece of paper and letting it out the room. I’m not risking my LiFe to do that sorry.
