I hope this helps, and I am dealing with a problem of those butt-faces myself on my banana. Here's a process I learned from my mom:

Mix a solution of
1tsp salt
1tsp liquid soap
a quart or two of warm water.

Mix well and use a soft cloth damp with the solution to clean off all leaves of plant, rinsing and reapplying solution to cloth often. When completely dry, inspect leaves and physically remove any eggs or bugs with the cloth. When the plant seems free of all physical signs, let plants dry and apply a spray insecticidal soap (I use Garden Safe brand, by Schultz). Repeat once a week until all signs of infection are gone.
