Hey everyone! So I recently discovered a couple of bugs at my friends hydroponic garden. Seems like a pretty bad infestation. I know they are aphids but they look different so I was wondering if they are two different kinds of aphids? Also I have treated them with insecticidal soap. This is more of a deterrent than a solution though right? Also I have provided picture of the soap and brand. If anyone has any comments as to the brand of soap I am using and maybe recommend another brand it would be greatly appreciated!
