There must be some good ad networks targeting spanish language sites. Have a look at some other similar content sites in your language to see what they use. If that fails, sign up for a program paying per sale. CJ and Tradedoubler might be worth a try for instance.
I use google on a swedish language site and it works really well. I think it has more to do with number of visitors and what kind of content you have. And less with non english language.
Edit: Noooooo, I just replied to an old thread. Oh well.
I agree that adsense is not that Good for Non US/UK/Aus traffic, but that is what challenging part of it.and if you hate adsense ,perhaps you can try cpa program such as cpalead, they are international friendly, in my case they even have ads that serve my mother tongue that means targeting my country audiences
