Attack of the [other] mites

Remember when I said that mites (maybe I said bugs before) were the bane of my existence?  Well - they still are.  I still have a lot to learn from other organic gardeners I gu"ess. 

My mom recently sent me a lovely quote - which I find very useful right now. 

"I have not failed, I've just found 10,000 ways that won't work." - Thomas Edison

I just went back outside today to check on my plants again ...I don't know how on earth I missed this before, but my dill plants was just absolutely infested with mites.

In the picture on the right, the brownish spots on the left stalk are not mites, but just brown/dead spots on the stalk itself.  The mites are the little green spots all over the stalks.  Keep in mind these are different mites than I had before.  The ones before were red spider mites.  These are not the same - so I have not completely failed.  I did seem to get rid of the mites before.  Well because my dill was planted in my container that also has my cilantro, nasturtium and zucchini - and because it was completely infested I opted to tear it out and dispose of it.  As you can see below I have quarantined it =P in a trash bag along with the one zucchini leaf I found mites on.  The rest of the leaves seem fine but I'm sure it will be struggle to keep them away.  I just sprayed the entire container with the organic insecticide I have now that contains neem oil. 

Goodbye dill! I shall miss your lovely flavor - but I won't wait long to replace you with another non-infested starter.

This leads me to my next question - how to keep these darn things away.  I've seen some starts at multiple nurseries that are already infested with mites.  Needless to say I now stay away from those - but even when I do they come around.  Other times I'm guessing they were in the soil I was using.  Seems like they are just a regular pest that I'll have to plan to fight off of anything I get, even if I start something from seeds.
