Yes.... I know.... but you left out the most important activity: running around screaming like a madwoman while doing the rest.
I did learn a cool new tip at Wikipedia, and I already have all the equipt: A useful trick against fleas is to burn a floating candle in a plate of water with some cleaning agent. Fleas will be attracted to the light and will drown. This trick also works when putting the cleaning agent water under a lamp.
I have a boxful of tea candles and plenty or saucers, and a bottle of soap I don't like but that smells nice. And Hardi is motivated to vacuum as often as I ask, daily if I ask, in the affected areas.
Oh, darn....I think this means that the houseguest for that upcoming church workshop will have to stay with someone else after all.
