A: Thanks for your inquiry. The best solution would probably be to create a vapor barrier with plastic over the dirt, lay down wire mesh and apply a thin layer of concrete over the ground to "rat proof" the area. This combination should eradicate any odors and in turn create a more functional storage area.
