I have been adding copious amounts of compost to what once California adobe for years. Now, I have rich loam and...huge (3+ inch) grubs. I did some research on the grub issue and have read that they are more common in soil high in organic content. I have milky spore on order to (hopefully) help combat the issue but was wondering if anyone else has run into this issue? If so, any other suggestions outside of pesticides (as we don't use them? These are not the common turf grub (in fact, I have not found any in the limited grassy areas we have) but rather, their population is exploding in the garden and vege beds (and are now settling in the potted plants). I realize that milky spore may not help due to the type of grub but I am desperate to tackle this issue as they are causing horrific damage at this point.
