Centipedes are scary because they have so many legs and they scurry very fast with incredible agility. In general I think we feel a revulsion to small critters with that kind of speed and agility. But if they’re too small (fly sized or smaller) then it’s more annoyance than revulsion.
The many legs thing is a real mystery though! I think it might be some kind of proxy for venomous critters, as spiders and centipedes have more legs than insects and also tend to be more venomous (apart from some Hymenopterans).
