Well, yeah, but I think it's bugs being all tiny and crawly that offends Alex. Like, I don't think she'd actually freak out about a really large bug, but many little bugs? She'd burn them up with her laser eyes, or fly away all dramatically. I bet she's probably actually screamed publically in front of the group at the sight of Swarm's masses of bugs on multiple occasions, like all high pitched and zero chill, too.
