"I think the main problem is when you kill the worms they are full of eggs. So you have to have a strategy to kill them also."
Yes, very tricky. Damn eggs are like seeds...hard to kill. I think that's why many herbs say to go on for like 10 days, then off for 5. This allows the eggs to hatch, therefore (in theory anyways), making the baby worm more vulnerable to the herbs (or freq). Seems like you gotta be really diligent with these worms. That's why we are plagued with them...they evolved to be elusive and survive.
