hmmm, well I looked it up on the internet, how to use the soap and oil and water combination. I sprayed the leaves with the concoction, killed them instantly but came back 2x as much in numbers. Darren, the soap and oil and water combination did not kill your mgs? is it safe for them?

Come to think of it/forgot to mention....before these little black bugs appeared, I massacred a whole population of these insects as shown below on the picture (they are gnats? yes? no?). When the population of these guys went down, the little black bugs then started appearing.
