My question is, can fleas live in and on furniture. If so for how long?
Yes and no. As explained in our FLEA CONTROL ARTICLE, adult fleas aren’t comfortable out in the open so yes, they can live on a couch. However, they won’t last long. If any person or pet came to the couch, adult fleas on it would naturally seek this warm blooded person or pet hoping to hitch a ride and to take advantage of what this host would provide: a stable living environment. As our article explains, if you left a flea on a couch without food, water or shelter, it would probably die in 5-8 days.
