The flea life cycle

Fleas are small, wingless insects with amazing jumping abilities. As they can reproduce super-fast, it’s crucial to treat fleas on dogs and cats all year round with FRONTLINE PLUS.

Female fleas feed and breed on your pet, laying up to 50 eggs per day. The eggs fall off into the environment, particularly where pets rest and sleep. In warm, humid conditions (like your cosy home in winter), the eggs hatch into microscopic larvae in a few days. The larvae look for humidity, move away from light and feed on organic debris in the environment, especially faeces (flea dirt) produced by adult fleas.

Within a few days, each larva spins a cocoon, and then pupates to a new adult flea. When environmental conditions are optimal, the development cycle from egg to adult flea may be completed in 2 weeks, but fully formed adult fleas can survive in the cocoon for up to 6 months. These pre-emerged adults make up a large reserve of parasites in the environment that can immediately emerge to jump onto a passing host, like your pet. In this way, the cycle begins again and adult fleas can re-infest your pet.

* For paralysis tick control on dogs FRONTLINE PLUS must be applied every 2 weeks. For paralysis tick control on cats use FRONTLINE SPRAY every 3 weeks.

Fleas can infest your pet from an early age, so regular, consistent flea treatment must begin from the time it is a young puppy or kitten. The good news is, that once on your pet, FRONTLINE PLUS kills newly acquired fleas within 12 to 24 hours of contact. By treating your pet regularly, you’ll protect your home from further infestations too.
