This is my first time ever to have a vegetable garden. Actually, I don't have a green thumb at all, and so I'm trying really hard, and surprisingly, my veggies are thriving...but now I have fireants in there. I found a huge fireant mound built up around my cucumber plant. I read online that DE was the best option, so I got some from my brother who uses it for his pool, but then read you can't use that DE in your garden. I'm so confused and frustrated and just want the darn ants out! I tried some home remedies by the cucumber plant - coffee grounds and mint soaked cotton balls have helped some, but they aren't gone. Now, I've found more over under my tomotaes. Any suggestions?
