"There's something inherently scary about bugs and creepy crawlers before you even apply them to horror. Rationally, they're so much smaller than us, so we shouldn't be afraid. But they can bite, sting, and carry disease. Some are venomous, and some swarm in large enough numbers to be dangerous. That doesn't even touch on how just the sight of them triggers a visceral response; they make us squirm. Naturally, horror often exploits that fear.
Take Arachnophobia, for example. If you didn't have a fear of spiders before, this horror-comedy makes full use of the eight-legged critters and gets under the skin of even the most fearless. And much like Arachnophobia, these other ten horror movies feature creepy crawlers that'll have you reaching for the bug spray."
