This was either a horror or a sci-fi movie that involved insectoid monsters or aliens. I think the monsters weren't sapient, they were more like animals and they attacked in a swarm. The monsters hunted by smell, so the protagonists ripped up their corpses and used the organs of these monsters to mask their own scent.
I remember one scene where the humans were trapped in a train car or a truck or something like that with a lot of small windows. The monster swarm was attacking them, but they smeared this gross stuff from monster organs on the windows, and the swarm stopped attacking.
I don't know how old this movie is. Probably like 20+ years
