Is it worth using flea prevention in winter? Here's the case for year-round protection versus seasonal treatment.
The seasonal approach
Some owners treat only during peak flea season (spring through fall) to save money. In very cold climates with hard winters, this can work — but it carries real risk of gaps.

Why vets favor year-round
Fleas survive indoors year-round thanks to central heating, and mild winters are increasingly common. A single missed window lets an infestation take hold, which costs far more to clear than continuous prevention.
Consistency prevents infestations
Because the flea life cycle includes eggs and larvae hiding in your home, stopping treatment lets a new generation emerge. Year-round prevention breaks the cycle for good.
