Honey Bees Use Animal Feces as a Defense Against Giant Hornet Attacks

For the first time, honey bees (Apis cerana) have been documented using tools, specifically animal dung, to defend their colonies in Asia. To defend themselves against giant hornet (Vespa soror) attacks, which can wipe out whole colonies, honey bees forage for animal feces and apply spots of it around their nest entrances. Giant hornets were repelled by feces-covered entrances, limiting their ability to mount deadly group attacks.
