I think you're conflating your own phobia up with something more fundamental.

I've certainly never found them even a little bit frightening. I've definitely felt like "someone's home" but it's probably the big eyes bias.

I would not characterize it as phobia, so much as I find them disgusting for some reason, dirty and unclean.

It's just your conditioning. If you look at it from another angle you can see that they are actually harmless and clean. And even playful amd cute if you goof around with them a bit.

Maybe it's about being grossed out by cobwebs.
