Scientists say they are by training bees to find unexploded mines, using his perfect sense of smell.
Professor Nikola Kezic, University of Zagreb, who heads the research project funded by the European Union, said that when established supply points within an experimental marquee tent, bees gathered mainly in containers having a sugar solution mixed with TNT.
He added that the insects are faster and safer than sniffer dogs to detect the scent of unexploded ordnance.
The researchers say they hope to develop the concept, making it an indispensable tool clearance.
It is believed that some 90,000 land mines remain buried in Croatia, after its war of independence that ended in 1995.
