Sorry, hon. I have some Sphagnum moss--but it was vaccum-packed (in a block, so I had to soak it to get it to 'expand'). I knew that stuff was okay to use right out of the package...not sure what to tell you about fresh stuff. I know some people on here bake their wood bedding before using it--to get rid of buggies... But I don't know if you can do that to moss.
