The life cycle of a flea includes three main stages: egg, hatching, and pupation. Normally, fleas can survive up to 185 days in a host, but they can survive longer than that if the environment is ideal. Fleas’ lifespan is also dependent on the temperature and humidity, as well as the availability of blood.
Flea larvae are blind, though they do have primitive eyes. They live in dark places, so they rely on their senses to find their hosts. Light, heat, and phototaxis are three of their preferred senses, and they’ll be attracted to bright lights.
Once the larvae exit the cocoon, they begin a countdown to their first blood meal. Their metabolism accelerates quickly when they’re out in the world. If they don’t get an immediate blood meal, they’ll starve to death. In some cases, fleas can survive up to a week without feeding.
Fleas spend more time in the sleeping area of their host than elsewhere. They feed on blood and organic matter. In a warm, humid environment, fleas can live for several months without feeding. This means that it’s important to treat fleas as soon as you see them to stop reproducing.
Fleas are a pain in the neck. During their infestation, they may appear to be invulnerable, but they don’t reproduce for long. It’s important to keep your pets and carpets free of fleas if you want to stop the problem from spreading.
