Lifecycle and Growth

Brown Rat Flea's life is a journey of transformation - an adventure marked by the following captivating stages:

Egg → Larva → Pupa → Adult

The Brown Rat Flea undergoes a host-dependent lifecycle comprising four stages: eggs, larvae, pupae, and adult. The eggs are laid on hosts, larvae feed on organic debris, pupae develop in concealed spaces, and the adult fleas re-infest new hosts.

Brown Rat Flea Behaviour and Adaptations

The Brown Rat Flea is a resilient parasite known for its adaptability. Its behaviour involves clinging and feeding on a host, usually a rodent, where it can reside for extended periods.

For survival, this flea has evolved to withstand harsh climates and can go without feeding for several days. Additionally, its powerful hind legs facilitate effective jumping to switch hosts when necessary.
