I have a few leaf footed stink bugs. I like to bug 'em! I go out several times a day and wave my arms over and around them and eventually they decide they HATE my garden and move it along. Horn Worms get hand picked.
I have ants aphid farming on my southern peas and also the egg plant. That has been frustrating. Neem, soap, blasts of water - even WASHING them off with a wash cloth and soap and water then putting diamotaceous earth around the plants has not helped. However, now I am getting loads of butterflies and lots of bees including and bee flys so I won't use anything else at all. I hate to kill my pollinators! I need them!!
