Good pics of the dead mites. Neem to kill many types of insect predators has been around a long time. I first heard about several years ago on OG. I only had spider mites once, they came in on a clone from a friend of mine. Fortunately, I caught 'em early and sprayed the undersides of the leaves with alcohol mixed w/water about 50/50. It kills 'em on contact. Then you spray again with just plain water.
Another thing that's helpful, if you can do it, is take your plant into the shower or ever a sprayer on a hose outside and physically wash 'em off. I had a friend who did that 2-3 times a week until his Predator Mites came in the mail from Canada. They're slightly larger than spider mites and they're reddish orange whereas spider mites are white w/a couple dark spots. The Predator Mites just mount the spider mites but instead of having sex with 'em they stab their hypo fangs into 'em and suck their bodily fluids like a vampire. They can eat about 40 mites a day or 30 mites and 10-15 egg sacs. But you get a couple thousand in the little bottle of what looks like sawdust that you just sprinkle on your plants. Then, when they've killed all the spider mites they start cannibalizing one another. Look it up online if you wanna try them. It's like $30 for 2,000. Anyway, just another option.
If I ever get 'em again - which I won't! - I'll use the Quantum Apocalypse. It looks like it works well... and that's all good. :thumbsup:
