Generally speaking, an adult flea only lives for 2 or 3 months. Without a host to provide a blood meal, a flea's life can be as short as a few days. Under ideal conditions of temperature, food supply, and humidity, adult fleas can live for up to a year and a half.
Only adult fleas live on pets. The rest are in the environment, so the number visible on your pet is only the tip of the iceberg. Adults are usually 1/16th to 1/8th of an inch long, red-brown in color and have three pairs of legs, the last pair quite large and well adapted for jumping. Fleas are wingless.
