Fleas are California's State bird when it comes to owning outdoor pets.
The best, cheapest and least toxic method for getting rid of fleas is sprinklingall over the floor, leaving it in place for 24 hours, then vaccuuming it up and repeating the procedure several times a week until the fleas are completely gone. It is considered safe for carpet and most upholstery.
If I'd known of those miraculous properties at the time I surely would have saved myself a lot of misery. But I'm talking about the family who had to endure scabies treatments not a year before that. Sulfer baths and public ridicule. On reflection there's no way I can be sane after all of that backward BS. No, they kicked me out because I eventually got strong enough to beat the redneck back (lightweight kitchen chairs are often tougher than they look) and I happily lived on Lookout Mountain (just under Rock City) with Scout training until arrested as a runaway while visiting a friend to pick up soap and paper.
I'ts a long story but my health and hygiene was far better during the two months I was playing the hermit in a cave by a mountain stream. Never saw a rat out there once - that species may have evolved to follow mankind around specifically. We certainly throw out enough edible waste out to sustain them.
And Ronnie Reagan liked it too.
