I use Lemon or Orange Dawn diswashing soap diluted around 20 to 1, 10 to 1 if I find a lot and I sprinkle can the areas where they are found. Usually mine are under rocks they seem to like compost, mine has leaves and twigs as a main ingrediant. If I used cardboard under the mulch to line an area to kill weeds they are in the cardboard. When soaked they die almost instantly and none come back. So far the soap has not made any plants sick.

Oh thank you so much!!! I have to wonder if that may work as a barrier for the whole house too... maybe wouldn't hurt to try around the perimeter of the house? hmm... Nevertheless, I will be on my way to the store for the orange dawn asap. THANKS!!!!

I shouldn't need to throw away any rhizomes unless they're just too gone right?
