Cockroach composting

Yes, really. They’re really efficient converters, eat anything, don’t smell, they shed their skin, which is an excellent addition to the compost, and new cockroaches can be sold or given to pet shops for reptile food (they have to be contained of course – you don’t want them in your standard compost heap).
