Squash Vine Borer

I should stop asking if anything else could go wrong.  Of course it can!   This garden is getting the best of me this year, but I'm a fighter.  I pulled a wilted stem off my zucchini plant tonight, and guess what?  A big white grub was inside the base stem.  I have noticed some orange powdery stuff around the base, but didn't think it was important.  Apparently it is.  It's a squash vine borer!!!  YAY!  Now that it's identified, it will be destroyed.  Maybe I should go back to the ground soaking sprinklers.  That seemed to work better last year.
