Why do creepy-crawlies creep us out?

Pest control is a billion-dollar business for a reason: Insects and arachnids are the all-stars of nastiness. They reproduce like crazy (a single female aphid, for example, can produce 600 billion offspring in one season)! They have horrible eating habits (houseflies vomit digestive juices on everything they eat and then slurp it up like a sickening soup). They sting or bite (Australia’s funnel-web spider can kill you if you don’t get the antivenom). Their furry legs and murderous jaws (called mandibles) inspire sweat-inducing phobias (intensely strong feelings of distress triggered by specific things).
