Inez Sue told me about this product: http://forum.lowyat.net/index.php?showtopic=2034579&hl=

This evening, Inez was so kind, she brought some over for me to try.
Rosie is the one with two fleas (I spotted them that day), so I’ve dusted some of this Earth powder on her fur.
According to the website, it can be ingested and/or dusted on the animals’ fur, or sprinkled on any surface.
