Our cotton plants are suffering from an aphid infestation right now. My favorite solution is to buy a container of ladybugs and release them in the evening for a night of slaughter. This time, there was a nest of ants providing escort for the aphids, so my first wave of Coleopteran warriors was driven off with minimal casualties inflicted on the enemy.
The ants were reaching the aphid collections up the stems of the plants, so what I needed was some kind of barrier. I tried Vaseline, but it was a pain to apply. I bought a sticky glue designed to catch insects, but a closer reading of the label said it might harm the plant and extra work was required to use it safely. Finally, I took a chance and squirted corn oil on the stems.
