City Guides: Fleas Across Spain
The cat flea (Ctenocephalides felis) is responsible for over 95% of flea infestations in Spain, on both dogs and cats. Spain's warm climate allows year-round breeding indoors. Fleas can transmit tapeworms and trigger flea allergy dermatitis in pets — environmental treatment is essential to break the lifecycle.
Risk level, season window and prevention priorities vary with local climate. Pick your city below for a local guide, or start with the complete flea guide for Spain.
