Sns 209 Anyone?

Has anyone had any success with sns 209 as a soil drench? I keep getting these pesky gnats and want to get rid of them in a decent manner. I also noticed some root aphids and I hope it gets rid of them as well. It's really not that bad but just want to nip it in the bud before it does become a problem. Also would it be bad to use in flower? Most things I have read said that it's very gentle and doesn't effect the taste of the buds.

get gnatrol, works like a charm for gnats. That said root aphids are another story.
