Answer: There are lots of eco-friendly products on the market now and they are all plant based. Vinegar, neem oil, horticultural oil and even boiling water can work if they are carefully applied. Colorado State University has a publication addressing these issues. You can download a copy and give their controls a try in your own garden.

Best wishes with your garden!
