Sounds as plausible as anything... Tell your buddy to try this stuff.

A word of warning here: diatomaceous earth is very hard on traditional filtered vacuums. Unless you're only cleaning a small section, we recommend using a shop vac to avoid burning out your vacuum's motor.

The stuff might NOT be too good for your lungs either. I use DE in my pool filter but I would NEVER put it on my bed... or anywhere I might breath it in.

We used diatomaceous earth to get rid of a huge flea infestation due to skunks setting up under the house. We don’t have carpets, which made it easier. But fleas can live a long time without eating and are damnably hard to kill, so finally we had to use the propane torch outside.
