no doubt that will work, no doubt at all.
I get these bastards once yearly, in spring. Ant come in my room like an army, I watch them because....
so far they've always gone for one plant in the room. The ants colonize a plant, farm aphids, and eat their poop I'm guessing.
I watch them do it. some are kept in the dirt and some on leaves and stalks. only one plant mind you.
I pour neem/soap in the one plant surface dirt and foliar, and the ants bum out, some die, and the foliar kills the aphids it covers. I rake up till I see the ant farm inside, do the same again.
I do this for a few days in a row, then again if I see ants around even. always has killed them right in front of my eyes. only time I ever see these too, in the spring, once.
I promise you an aphid cannot survive if covered in oil,. peppermint, dlimonene, thyme and rosemary oil has worked so far the same way. go outside, catch on and cover it with canola oil ,it dies. I watch them wiggle in the oil, then stop moving.
I wouldnt fuss this way for an outbreak, but I dont get outbreaks with multiple plants. I know many things will kill these bugs and others, while I'm no fan of neem oil I do see it as safer than a chem as a first defense. theres vids of greenhouses destroying the
bugs with neem/soap alone, they do die, check it out. neem kills aphids, wont control a room infestation.
same page?
if wants to get rid of these aphids in one plant...oil works for me year after year. when its time to rid the rooms...I'd do what your suggesting without question.
