In reference to wheat flour/buttermilk mite remedy:
Actually, I should have said "no, I've never used it myself." I rarely use any pesticides these day, and even those are mainly limited to soap and pyrethrin.
Neem oil has some very few legitimate uses but is touted as a panacea. And there is no such thing as a panacea. I would have warned you off that...
Lime sulfur, maybe, as per info at:
BUT! I wouldn't expect any remedy (even Kelthane, if you could get it) to help at this point. But dusts (flour or mineral) are legitimate remedies for insects and mite pests. Call them 'particle films' and they even sound ...exciting:
Which takes you to:
"Although not mineral-based, Ghate and Marshall (1962) suppressed eggs and mobile forms of European red mite and two-spotted spider mites with a combination of buttermilk and wheat flour."
The kaolin-based product, Surround (R), which is mention in the document cited above, is available mail-order to home gardeners from various places (if anyone is interested).
Hell, even people who *don't* live out in the country are surrounded by other peoples yards with plenty of trees, bushes, weeds and flowers which are *completely* beyond their control, let alone being beyond their
*budget*! Why did you assume I meant such a hugely extensive action?Perhaps I should have thrown in the word "immediate" before "vicinity." As in, if you have a row of raspberries, or a hedge row, or a couple of peach trees next to the garden, spray *them* (they almost certainly need the protection, after what's happened this year).
Next year, you will need to invest in prevention, which is always less expensive and more effective than trying to cure. (Prevention is less expensive, though not FREE.)
Right now you are hit hard with "throwing good money after bad" regret/anger, and the fact that the most reasonable action at this point is to destroy everything you planted for this year, which hurts.
HURTS BIGTIME!
