DE powder like what you use for your pool?
@Irispixies: Yes and No.
Filter DE is slightly different than garden DE. Or at least so they say.garden DE will cause the exoskeleton on the bugs to be scratched and basically think of it as getting infected.I however use a flea control on my pets that sterilizes the fleas. This in turn causes the population to decrease to zero after awhile. 4951
