Hi Lynn, I've actually never heard of it. Pretty neat. I have, in my research, decided to order joshsfrogs mite spray. I have not had any mites nor do I want any and would like to be prepared.

Though, my two cobalts eat so many ff that I doubt I'd get to the 28-30 day time frame when they usually invade. I start each new culture 2 weeks after I start feeding out of the current culture so the new culture is ready 2 weeks later. So far so good (crossing fingers).

Let me know if you give the shelf paper a try. I'd like to know if it works well .
