How do you dispose of the trapped flies? How do you reuse?

Yes, way too nasty. It gets tossed in the trash

I just dumped out the dead flies and matter into a plastic grocery bag and then disposed of in the trash. You can purchase replacement bait at Lowe's, so able to use the trap over and over again.

You don't reuse it....it's disposable. You would just throw it away.

I found that if you just put the entire trap in a small shopping bag, and tie it shut then put it in your trashcan. The traps are not reusable once they're filled. Also make sure you wash your hands after handling the traps.
