Before nightfall, people would scatter the leaves of bean plants on the floor by their beds. In the morning, the leaves would be full of immobilised bed bugs, which could then be taken outside and burned.
Its hot science news. But is it something I can try out for myself? Should I start sprouting beans and spreading the leaves around?
