In the bad old days, a product called Black Leaf 40 was used on mites.
It is a 40% solution of nicotine sulfate. It is highly toxic, so it has
pretty much disappeared. IIRC, it is supposedly still available for
use by poultry farmers to control mites in henhouses. I don't know
where you could buy it.


Nicotine smoke bombs were another scorched earth approach
in greenhouses. Unfortunately, Nicotine doesn't kill eggs.
