I never seen that stuff but I know that dog shampoos that have tea tree oil has a similar effect.
One place I lived had dew worms, they get big like nightcrawlers and will make a yard lumpy as hell. One day I was giving my dogs a bath outside and I soon noticed I was surrounded by worms crawling out of the ground everywhere that I had rinsed the dogs off at. It only worked with that one shampoo that had tea tree oil in it.
