Be careful with the ozone, it can eat certain plastics.
I've been through this animal infestation situation and just treating one area where the smell emanates is not going to bring good results. You really need to pull everything out where an animal could have traveled. They will chew through things you can't see like wires and ducts, where a fire hazard could be the result. They will also urinate and defecate through the entire area of their travels. Just pray that they haven't entered that space between the lining of an oven, if you have one. It is one of their favorite spots as the smell and fiberglass insulation draws them in. You will need to dismantle the oven if they've gotten in there.
