Money plants are remarkably tolerant plants. I'll bet if you just let the soil go dry (even completely dry) between waterings, the numbers will wither to nothing all by themselves.
Bugs are just another type of living organism, the same as a pet, or a plant (or a butterfly). While most of us might not go to the extreme of allowing bugs to populate a wall for a time, perhaps the purpose of Janet's anecdote is try to get everyone to look at the big picture, and not just automatically reach for the kill solution every time nature doesn't follow your human demands. Death might still be the answer, but there is a reason why things happen from the natural world's prospective, and often the solution is in the root cause rather than treating the result (the bugs, in this case).
