you will not eradicate this it is here to stay and to wide spread the areas that test the more it is found. it took over a thousand tests in one small area to find it here and even afterover a thousand tests in a different county it was not found but the next year it was found there. look at a map from thirty miles north of madison WI and at least 50 miles west of there then down to Dekalb Co. IL and that is the known effected area and growing every year.
