Do you also like ants, scorpions, mice, and cockroaches? If not, you could use negative feelings about them for inspiration.
I personally don’t mind spiders, if they keep their distance, but I can’t stand cockroaches. I don’t like their bug eyes and front nipper-things and their multiple legs and the noise they make if they run across paper or a plastic bag. I have had the misfortune to have one in my bed once and I hate the quick, scratchy little tickle of their feet if they get on you. They’re small and fast, so it’s hard to keep track of where they are, and they can cling to any surface, which I find makes them less predictable and scarier than, say, mice.
Some of this may relate to spiders, too.
