How do you find the queen ant of a colony?

ant queens are generally much larger than normal working ants they have wings as well on their back this makes it easier for them so that if their colony is destroyed the queen ant can fly away and make a new colony.you can find them deep inside a ant hill the only way of doing this is by smoking them out or by destroying their hill and the first one to flight out will always be the queen ant

hope i could help
