During my first degree, the house I lived in was Edwardian and had fireplaces on every floor. Unfortunately one of the two chimneys wasn't blocked up properly, so I would forever have huge black spiders appearing out of nowhere. I absolutely hated living there because of that, I was always on edge and searching the rooms to make sure they were spider-free.
During my current degree I'm living in private halls which are in a Victorian building, but luckily it's a lot more sealed than my previous accommodation and so the only spiders I routinely see (maybe once or twice a term) are house spiders which I'm used to. On two occasions I've had to deal with smaller versions of the demon black spiders like those in my previous accommodation, but I worked out that I must have accidentally brought them in myself on parcels/shopping bags, so I always check things before bringing them into the sanctity of my room!
