Bleach is great at disinfecting, but not so great on eliminating odors. You'll be left with a clean, but still smelly problem. Urine already has a high ammonia content, so adding more ammonia is only going to exacerbate your problem. And whatever you do, NEVER combine bleach and ammonia.
Most of the time, the lingering smell will go away on its own within a few hours to a day.
While bleach is great for fighting stains, avoid using it for puppy accidents. Bleach will not kill the odor of dog urine. It simply disinfects the area.
Try to narrow it down to the smallest area possible. If you can't physically see the rat within this area, then the rat may be in your walls, under your floor or hidden in a hard to reach place.
Bleach is excellent for eliminating foul-smelling bacteria, therefore both disinfecting any remnants of a dead rat in addition to removing the undesired smell.

Steam clean carpets and upholstery; this is a powerful technique to remove deeply embedded pet odor. Use baking soda. Sprinkle it on carpets, pet bedding, or upholstery and let it sit overnight before vacuuming it up. Use diluted vinegar.
Unfortunately it may take three weeks or more to completely decompose. A professional may be contacted to break through and rebuild affected walls. This can be costly and not a viable option. Even after elimination of the source of dead rodent smell, the unsettling scent may linger for up to two weeks.
Vinegar: Renowned for its natural disinfectant properties, vinegar can effectively absorb odors. Create a solution by combining vinegar with a few drops of lemon juice and leave it overnight in the most affected area. Coffee Grounds: Dampened coffee grounds or filter packs can absorb odors effectively.
