How do you dispose of the dead flies and any leftover liquid after the suggested 30 day period?

There are a few ways that you can dispose of the contents of your Fly Trap, and they all involve dumping the contents into the trash. You can pour the contents into a sealable container like a Ziplock bag and throw that away. Regardless of how you dispose of the trap contents, we recommend using some kind of trash liner or plastic bag to contain it and manage the odor.
