Horror Movie with Giant Rats or Something

by Notorious

I have been looking for the title of a ceretain movie for many years, and I think it was 10 years ago that I did the same thing I'm doing right now...ask the experts on a particular site if they can help.

Until now all I have gotten is a theory that the movie I'm lookin for is 'The Food of the Gods', but after reading the plot at IMDb it doesn't sound like the one I'm looking for.

I watched this movie first when I was around 8-9 years old, that's like 20 years ago, so it is probably a 70s movie, could be 80s too. I remember a few scenes from the movie and I seriously hope all of the scenes are from the same movie - I could be mixed up after so many years.

The first thing I remember about this movie is giant rats that eat people. I remember a bunch of bikers, on Harleys probably, roaming down a dusty road going somewhere. They end up at some deserted ranch in the desert it seems.

Secondly I remember all of the bikers resting on the floor or on some big bed, they all sleep close together, sharing the space. I remember one particular biker was banging (*ahem*) his girl, and his friend beside him was disturbed by his hard banging, he woke up and said "Do it downstairs", don't know if this is important but, it's what I remember...Hmmm.

Finally everyone dies, and there's only 2 survivors I think, a guy and a girl. They cry and scream running out or somehow end up outside of the ranch (or wherever they are), and there are a bunch of vehicles with people in radioactive suits (the yellow ones). The team was doing some study on the rats or on the area, or they were spraying chemical on the area, so basically the two survivors think they are saved.

The survivors are very happy and thank one of the guys with the radioactive suit, and that guy takes of his gas mask and it turns out he is one of the giant rats! END

That's all I remember about this movie, I hope someone can help me!
