I don't get it. They don't test for Azadirachtin (neem oil), which is questionably worse than Spinosad from my research. It's a very low toxicity bacteria chemical with a very low side effect profile at high doses. So what gives? Why do they test for Spinosad with such strict testing requirements? I haven't had to spray yet, but I find this to be a little bit silly. Or is there something I don't know? Is it any different when burned?
