First, I only want to use eco-friendly methods of ridding pests from my garden. That said, I've got two questions: I had a bug recently that killed the broccoli and cleomes and I'll attach a pic I found online of it (http://www.malawicichlidhomepage.com/macro_nature/DSC_3299.jpg). We since ditched the broccoli and cleome plants and now they're gone, but I'd like advice for next year. Second: I've got oleander aphids. How to get rid of them in an environmentally friendly way?

Thank you in advance...
