I saw this film 15-20 years ago. There were giant ants in the Amazon jungles. I think the forest is eaten. Then the ants came to the city and I think the ants were eating humans. Finally they died by fire or being drowned under water (maybe dam water). Does anybody have any idea?

Chosen answer: There is a movie from 1954 by Gordon Douglas called "Them". It's about giant ants that invade the city and eat humans but as far as I know, that's about it. Can't remember any jungle or dam water so it's quite possible it's not the one you're after. Or there is a movie called The Naked Jungle. It doesn't have giant ants, but it does have an army of ants. They cut a swath through the amazon jungle, consuming everything and everyone in their path. A plantation owner tries to destroy them by blowing up a dam.
