Turn on your fans in the car....found the Vent inlet that should be around the engine. No need to start the car unless of course the fans won't turn without the engine being on in a Subaru. Use a can of Lysol and spray down into the inlet using a good bit of the can.
Another way I would try first though is to let your car run outside for about 30 minutes with the Heater full blast along with the air conditioning button depressed. The heat will help kill the bacteria and the air conditioning will help stay off condensation while its doing so.
