Another spider mite article, courtesy of Isurus79...
https://extension.msstate.edu/sites/...007/bw0507.pdf
Along with a recommendation from him when looking for a bigger gun for spider mites: "Bayer 3 in 1 is probably the easiest to find pesticide containing imidacloprid, which is super effective against mites."
The struggle is real with these Catasetum spider mite magnets. ![Bowing](http://www.orchidboard.com/community/images/smilies/bow2.gif)

The article from Isurus79 and other articles, including the one I included below (in the application tips section), state that imidacloprid treatment can cause mite populations to increase, often at a very fast rate. This is especially frequent with the Two Spotted Spider Mite, but has also been observed in other mite species. The Bayer 3 in 1 has another ingredient that targets mites. Imidacloprid by itself can exacerbate a mite problem!

Mites rapidly become resistant to pesticides. Effective products need to be rotated frequently if used at all. Mechanical means of control do not lose effectiveness with time.

Bifenthrin is a miticide.

Bayer 3 in 1 took out my mites instantly. Had infestation in greenhouse, all orchids affected along with many other tropicals. Snake plant had it the worst. I must say after just one treatment I do not even see any sign of them over a month now. I really like Bayer products for all aspects of gardening.

I only have 3 catasetums so it'd easy for me to manage the best on them. I find weekly hosing down the leaf or wiping it does the job better than insecticides

I've currently got a mite infestation and I don't think they are spider mites. There is no webbing at all, they are tiny and red/orange. A little research has turned up the existance of flat mites or false spider mites, some even specifically called orchid mites. I bought 2,000 of the predatory mite Neoseiulus californicus from Arbico which I just applied today, fingers crossed they will eat them, whatever they are.

Just curious where are you releasing them. In a greenhouse, outside, inside? Definitely looks interesting these biological controls, although a little pricey. I guess if they work the price isn't bad at all. I am intrigued about the beneficial fungi and bacteria.

FYI: predatory insects aren’t sold intending to be a complete cure (regardless of what the seller says). They’re a management strategy that, included in an IPM program, can keep pest levels below the economically-damaging threshold. I’ve both seen and used other beneficial insects in greenhouses and they’re typically applied monthly throughout the season.
