A leaf hopper is not a desired bug ! And spiders don't eat mites.
It sucks the plants nutrients. Start looking at your stems closely and you will see them there too.
This is one of the reasons I never recommend using store brought sprays.. Not all work. You can use hand soap and mix it in a spray bottle with warm water and use that instead. Of course, spray a little on a few leafs to see how the plant reacts. I always wash off 10 minutes after I spray with soapy water to prevent the white residueyeah there leafhoppers this is what I been battlin I just gave up hopefully the smell in flowering will detour them, leafhoppers are attracted to the brightest "green" in the area so if the only thing that's nice n green is ur plants well there comin to kick it, they suck on the leaves, leave droplets n a white residue after they sucked I wouldn't say its powdered mildew cause ive seen that also them leaving those droplets then it just sittin there, but ive said something where I get my nutrients they said o don't worry about those they never have hurt my plants, ive looked for an organic way to get rid of them a long time and I tried some safer brand which saids it kills leafhoppers I used it but it made my plants look like shit after that I just left it alone, just keep your plants healthy and do what you can there a pain n the ass flyin everywhere when the plant moves

Are you arguing with science? If so it's a losing battleno, no they don't. just like your statement that leaf hoppers are a good bug is wrong . A spider isn't going to waste his time chasing microscopic mites on the undersides of leafs. He is going to spin a web and catch a sizeable prey. Even if a type of spider ate mites it would not keep the infestation down. You are assuming just because it is a spider it eats all bad bugs. LOL And spiders suck the body fluids out of their pray with fangs, What the hell are they going to put them in a mite ?
I don't think they could kill a plant, unless there was a ridiculous amount of them. They will cause lots of holes in your leaves if left unchecked.And if left alone can they ruin a whole plant?
