Necessity is the mother of invention. I had hundreds of aphids on my two month old seedlings growing inside and had to do something. I regularly spray with homemade insecticide which helps a little but can never really get the undersides of leaves well.
So I mix up a gallon of the homemade solution and give each plant a bath-dunk and swirl.
To prevent or at least greatly minimize soil loss while holding plants upside down while bathing. I simply traced the top of a 3-4" pot on scrap Styrofoam egg carton, cut it smaller until it fit at the soil line. Cut a slit to the center so I can slide the plant stem through and hole slightly larger held onto it while giving each plant (upside down) a vigorous swishing completely submerged. The plants loved it and now I have very few aphids. For the time being. I can't wait to get them outside.
