While they all can live in your house if unseen I think your parent really meant the allowed part of it. As in they do acknowledge the usefulness of spiders in general while also being significantly creeped out by them. Same here btw. And for other species too. Like ants. I acknowledge that they are very useful creatures so they can totally "dig up the lawn" and I don't care. They can also climb up the cherry trees and others and do their thing there as long as I get enough cherries to make jam and eat in summer. But as soon as even one sets foot in the house I try everything to kill said colony.
