I don’t have a very strong horror reaction to animals; I’ve known people who get the horrors from bats and from snakes, and I know of that reaction to spiders, but none of them bother me. In fact I find bats and snakes beautiful. And your reason for finding spiders less bad weighs a fair bit with me; when I spot one inside I usually transport it outside rather than killing it (except for black widows!). But then there was the time last year when C spotted a spider on our ceiling, and I climbed up with a drinking glass and a sheet of paper to trap it—and then miscounted the steps on our stepladder and took a fall. But the spider didn’t make its escape, so I was able to deposit it outside our front door . . .
(And then a few days later I had a medical appointment, and one of the routine questions was, “Have you fallen?”)
