We aren’t sure where you have seen this information. All decaying carcasses will smell though a rat is much larger than a mouse so the odor will be stronger and last longer if a rat dies. For this reason we do not recommend baiting inside with rodenticides like First Strike Soft Bait Rodenticide as you cannot control where a rodent is going to die. For rodents inside it is best to use snap traps and glueboards so you can control where they are going to die. You should also seal up all cracks and crevices outside that are allowing them access to inside.
