30-90 Days (Average). A flea might live a year and a half under ideal conditions. These include the right temperature, food supply, and humidity. Generally speaking, though, an adult flea only lives for 2 or 3 months. Without a host for food, a flea's life might be as short as a few days. But with ample food supply, the adult flea will often live up to 100 days.
If you mix equal parts of baking soda & salt and sprinkle it in your house, wait, then vacuum, then fleas will not live anymore. :)
Answer
Fleas have 4-stage life cycle. Control of fleas on your pet and in your home must address all stages of this life cycle. If you miss one, you have more fleas!
Fleas can live up to a year but without food it can live only a few days. Without a host, adult fleas live only a few days to 2 weeks. It seems that there are various life spans for different species of fleas.
Flea's don't live long, but the problem is they reproduce very fast. If you have fleas you want to call a professional exterminator right away.
