Dead animals in the walls of a house can create an unpleasant odor. You would be surprised at the amount of odor caused by something as small as a mouse.
Often we can locate dead animals behind walls using a special light scope. In an animal dies in an unknown area then removing it and cleaning the affected area is not all. It is also important to find the cause of the problem - that's why we will locate where the animal entered and seal the opening.
