I usually get these little dudes in the summer. I let them be when I can stomach it, but I have this one lamp at my desk pointed up at the wall to give me some indirect light. Occasionally a house centipede will crawl along in front of the light and cast a really long shadow to freak me the hell out.
Took a lot of getting used to when I moved to the East Coast for grad school. Supposedly they do live in my home state but I can't recall ever seeing one here. It's mostly spiders, millipedes, and earwigs where I'm from.
The thing that really freaked me out about centipedes is how absurdly fast they are. Also the one time I watched one crawling above me in bed and then it dropped onto my pillow what the fuck.
I've spent the last year or so trying to get myself to not jump out of my pants every time I see one of these things. Then roughly a month ago, I get up at 2am to take a piss, and as I'm opening the door this little fucker falls down no more than 10cm away from my face, lands right on my foot and would have probably run up my pyjamas if I hadn't managed to reflexively kick and launch it flying across the room. I think it must have been either sitting on top of the door or been trying to climb through the doorframe just as I opened it. Pretty sure I woke up everyone in the house, and probably the neighbors too.
Anyway, my phobia of these little shits is now 100 times worse than it was.
I got up one night around 1am to pee. I see maybe 3 or 4 of these little guys in my house each summer, so not very often, but enough that I am always on guard for them, so I turn on the bathroom light and put my feet on the bathmat, thinking it will offer some sort of centipede protection. I am halfway through peeing when one of those little devils apparates out of nowhere and runs full speed right at me. The bathmat does not slow it down at all.
I don't care what they eat. In my house, they are the worst pest.
When I was a kid there wasn't awareness of house centipedes. I remember my first time seeing one as a kid, it was night time and I was home alone. Some of the most visceral fear of my life.
That's honestly why they creep me out the most. Spiders will generally be chilling out in a corner somewhere you expect to see them, doing their own thing, and not moving much unless directly disturbed.
Most of my experiences with centipedes involves them darting out from under a baseboard at night and scaring the shit out of me when I'm only half awake. Then by the time I realize what it was, it's already scrambled across the floor to disappear under some other piece of furniture.
I have seen one of these in my life. I found it in my hair. I'm glad if already seen pictures of them on the Internet as the experience was already unpleasant enough when I could recognise what if found and knew it was harmless.
I know they're harmless and help with pests. But they got away too many legs and move just as fast for me to be comfortable with them. I'll take cute little jumping spiders webbing things any day over these.
