Had bad aphids last summer and used an organic spray that one can spray on vegetables and eat next day (or same day)…several brands out there.
The one I used had neem oil as main ingredient.
I bought a small hand sprayer at local hobby store and cut store bought organic spray by almost half dilution with water.
I diluted the store bought organic spray so I could do more spraying sessions closer together to get the eggs and also less film of spray on leaves (at full strength coats leaf with thick film that can effect some leaves adversely). I found the diluted spray worked well to kill aphids.
Avoid spraying buds and avoid spraying close to harvest. I spray up under all leaves (thus small hand sprayer for pressure to spray upside down).
I took my plants out of grow area and sprayed in tub. Never spray plants while under lights…will burn them badly. Then wait to dry before returning to grow area.
After all signs of aphids gone (about two weeks) I took plants back to tub and sprayed down with plain water to wash any residue and dead bugs away.
There are organic sprays one can make but posted this just for ease and rapid response. Avoid sprays that also kill fungus and molds and research still out on possible dangers of smoking neem residue so something to consider when using store bought sprays even when organic.
Also, cover top of soil so spray doesn’t drip down into soil while spraying (I used small plastic garbage bags).
mine looked worse than this…had bad infestation that kinda crept up on me…no more, “in and outdoor”, for me.
didn’t have a close up but here are two pics of the poor infested…all that leaf damage from aphids.
and yes even with rinse I’m positive I smoked numerous dead aphids…yuck!
