What is the stated life span of fleas?

• A. 1 week to 2 weeks
• B. 6 months to 1 year
• C. 14 days to 6 months
• D. Several years

Answer: (C)

Fleas have a short, environment‑dependent life span that ranges from a little over two weeks to several months. Under typical conditions with a host and adequate warmth and humidity, an adult flea can live for a few weeks to a couple of months, and the entire life cycle from egg to adult may span weeks to months. The range of about 14 days to 6 months captures both the quicker development seen in favorable conditions and the longer potential duration of the adult stage, making it the best fit for the stated life span. A range of 1 week to 2 weeks is usually too short, 6 months to 1 year is longer than the commonly cited span for the overall life cycle, and several years is far too long for fleas.
