Ive used bon-neem and ive used pyganic on aphids with great success. I only ever spray in veg and only until week 2 of flower before buds actually develop, never after that though. I only know its aphids because i just had them this summer in my veggie garden. First time coming into contact with pests for me.
Looks like some aphids and and a fungus gnat... do the dish soap bath @1diesel1 suggested... might have to do it more than once a few days apart if they're bad, they're really good at hiding nooks. Do it asap, they multiply like crazy. I preventative spray in veg with Lost coast therapy... I loathe aphids.
