I say it's nasty, because it is :wtf: ... I never had to use it, because I use a No-Pest Strip :thumbsup: ... however, several times, I have helped my friends apply it to their plants, and watched as it failed to get rid of the spidermites, after 3-4 weekly applications, (as advised) ... even after flushing, thoroughly rinsing, and a couple weeks to dry, etc., you could smell and taste the Neem on it :wtf: ... my buddy gave me a few ounces of his treated White Widows ... I thanked him, tasted it, and threw it all in the trash ... and, he still had spidermites ... that is why I'm negative about that crap ... as to not reading negatives about it, keep in mind, online Forums are full of 'parrots', that keep repeating things they've read, and have no experience with ... they mean well, are just trying to help others, but sometimes repeat faulty advice ... good growing !
