I definitely agree that killing rats will do little to solve the problem, but would still recommend poison. Taking the food away is important, but will not necessarily drive them away. Rats can and will eat anything and everything. They can live on your attic or wall insulation. They can find food outside amongst the wild. In my experience, if you don't eradicate the rats they will eventually become a bigger problem than you can imagine.
