I understand, why worms are so hard to kill is a mystery and an awful affliction. But u have children so suicide IS NOT an option. No one else will care for them and fight for their health like u! I dont know the answer as i have worms i cannot get under control either and i have done all the meds / herbs too. I have flukes not pinworms but worms the same. Have your kids seen a doctor? Have u tried diatemacious earth?
