If you feel there is a safer alternative that's still effective, I'm all for it. I don't use pesticides lightly, and I certainly don't spray them just because the calendar says to; I target its use to a specific threat, and I generally work my way up the ladder from mild/organic stuff to the hard shit only if I'm not getting results.
I hear your concerns, but I find that people who criticize without offering specific alternatives to be unhelpful.
Russet mites are nasty, populate wildly, and are so small (microscopic, need 120x just to see them) that they get missed a lot in people's gardens, which means they have had the chance to become resistant to many insecticides already.
