In case of a "mild" infestation, isn't it a feasible solution to have some plants, how about every week collect some leaves and tape around tightly the feet of the bed?
Beans are very easy to grow (the easiest plant I've grown at least).
I've actually did it in the past, it's an option for sure but the very nature of only working as a dry powder is quite limiting and makes the beddings dirty when they inevitably touch the floor.
