Maybe it's just me, but doesn't it seem like ants aren't nasty-gross like cockroaches and flies?

Ants don’t gross me out (unless I see them en-mass on my Baby Ruth first thing in the morning) like flies and especially cockroaches. Cockroaches make me want to shrivel up. Flies annoy me and I feel like, “Yuck!” when they land on me. Ants, on the other hand, seem like such nice, industrious, busy, clean little guys. So why does it seem like they’re cleaner to me than roaches or flies?
