Eeeks, I am getting more grossed out by the minute about these SHB. Linda, I have also heard about the predatory nematodes being used in the soil to kill the underground bugs. We use them here in my area to kill the bad bugs underground. It works like a hot dam!!!! My carrots, turnips, (all root veggies), when I apply these predatory nematodes do not get wormy, they are great little underground workers, yeah!!!
I wish you all the best of luck with your SHB, it is such a nasty thing I can't stand it!!!! Have a wonderful day, enjoy our life we have. Cindi
