news Honeybees deploy poo to ward off killer hornets © Getty Images Honeybee populations have been declining sharply around the world Researchers have found that honeybees in Vietnam collect and smear animal faeces around their nests to prevent deadly raids by giant hornets. They say the finding is the first to document the use of tools by honeybees. The bees used chicken poo, buffalo dung and even human urine to defend their hives.
