Hi,
I'm new to YT- my Roxy had fleas- they got in my bed. I bombed and vaccumed- they came back. I used
diatomaceous earth on the carpet and vaccum bag before I re bombed. It's non toxic to animals or humans- it's used in swimming pools. They say get a different grade, however, the lady at the pool supply store told me she had dogs and used pool grade with no problems. She gave me a "scoop"- (it comes in huge bags).
Also you have to get rid of the vaccum bag immediately- seal it in a plastic bag and throw it out. The
diatomaceous earth is some sort of crushed sea shell. Here's the link where I got the info from. Hope it helps!
Flea Prevention I also have had luck with ecalyptus oil diffusers- (if you like the scent.)
