Elephants can destroy whole fields of crops, especially where farmland borders reserves in countries such as Kenya. But they avoid beehives, and researchers have found that even empty hives are enough to reduce elephant damage, probably due to their odour.
In an article in the German journal Naturwissenschaften, researchers say that hives could be deployed like 'biological minefields' around farms, or could be used to protect valuable trees.
