I used to live in a condo, so the worst thing I'd see were the occasional ants. When I moved into a bungalow, we had to sleep on the floor the first few days waiting for the bedframes to come in. I woke up one morning, checked the mirror, and saw my first house centipede. On my head.
I slapped it off, screaming hysterically, and it ran back at me when it hit the floor. I spent a good two minutes crushing it (the slippers I wore that morning no longer exist) and I showered for a
long time. I think I used up at least half a bottle of shampoo.
House centipedes have been my greatest fear ever since
