We used to get massive (and fast) spiders in our house when the weather started getting colder in the fall. It seemed like it was always evening when we'd spot them, just before going to bed. We'd be turning off lights, getting ready to go upstairs, and there it was: a big, black spider in the middle of the room. It was my job to get rid of them, which usually involved a popping noise. I still shudder every time I think about this.
