MoonWrasse:If you cut up a flea collar and suck it up, it might help. That's what they suggest for curbing dust mites and fleas, as they can just get blown around the house by vacuming them up.
these guys would probably eat the flea collar and only get an upset stomach over it... Flea bombs don't kill them even... though they at least slow them down enough so a shoe (or even better a brick) can...
