Why FSM?

The Flea Susceptibility Monitoring (FSM) initiative

Imidacloprid was launched by Bayer in the US in 1996. Since then, over 100 million doses have been sold worldwide.

Bayer is committed to ensuring the high and long-term efficacy of its products, some of which have been in the marketplace for a long-time.

Bayer has been sponsoring the FSM initiative since 1999, to continually monitor the efficacy of imidacloprid for proven, efficient flea control.
