Rodenticides, colloquially rat poison, are typically non-specific pest control chemicals made and sold for the purpose of killing rodents. Some rodenticides are lethal after one exposure while others require more than one.
Yu definitely do not want to use poison to get rid of a rat problem. It does not solve the rat problem. It is inhumane, as the death is slow and painful. It does not kill all the rats. Not every rat that eats poison dies. The rats that do die will die in your attic or walls, and cause a horrible stink - I guarantee it.
