I am not in the chemical end of the business, but I am truely in need of help! My wife and I are currently building a house on a wooded lot. I have removed the trees from the vicinity of the house, but there are a large number of trees that are remaing and are covered in posion ivy. The leaves loook to be at least six inches long and the vines on the trees are over three inches thinck in some spots. I am worried since I have two small children that do not know what posion ivy is. I am looking for the most effective way to remove and kill the ivy. any help would be appreciated. thanks.
