How do you know if you have spider mites?
Does anyone have suggestions on what to get to treat spider mites? I'm not sure if my Zygopetalum has mites or dust under the leaves, and there are SO MANY options for just neem oil that I'm not sure what to get or how to apply.
I heard that the alcohol treatment doesn't really work. Also should I treat ALL of my orchids with neem oil? or just ones I'm suspicious of?
