That really depends on which types of spiders you are refering to.
Daddy long legs are a good option. Granted, they are spiders, but they eat other spiders.
Sometimes mosquito hawks will get spiders, but I find them creepy.
Some birds and bats like to eat spiders....
Frogs, geckos, preying mantises (manti?), other crawly/jumpy critters like that.
But, the best option to getting rid of spiders, besides killing them, is doing it yourself. Every day, break the web that pops up. After a week or two, the spider will move on. If it can't keep a web, it can't catch food, and it will starve. They aren't stupid, they will go somewhere they can get to keep their web. They all want to live just like us!
