go to this website, look at the sns 217 and the sns 209. They worked wonders for me. I have seen a mite since i started using it. If you call them they will UPS you a sample package of full size bottles. It worked amazingly! people will come in here and say ohhh use azamax and mighty wassh and blah blah blah, they all work, but this doesnt harm you plants, wont burn them and ITS FREE. They are giving full sized samples are right now so people will spread the news...check it out for yourself!
