The basement is the only place in the house that has carpeting–so if fleas live upstairs, they don’t really have anywhere to go (hard wood and leather couches don’t seem like their cup of tea). There are also four cats living upstairs that are flea-treated and wear flea collars, so they’ve never had a problem up there. I want to bomb only my apartment in the basement (which has a door at the top of the stairs), so can I hang out upstairs while the fogger is going on? Do I have to evacuate all the cats and people who live upstairs?

(Unrelated, but also a fear…do I have to clean my mattress somehow after setting off a fogger in my bedroom? What about my clothes?)

Thanks so much for your help!
