Home Flea Infestations

You can count on Simparica to prevent or quickly eliminate home flea infestations.

Delivers proven results

Simulation of Flea-infested Home Environment

  • Simparica administered monthly for 3 months demonstrated >95.6% reduction in adult fleas within 14 days of treatment and reached 100% from day 60 to day 90, the end of the study.1

Breaks the flea life cycle

  • Simparica kills adult fleas before they can lay eggs. In a lab experiment, dogs were infested with fleas and then treated with Simparica. One day after treatment, no viable eggs were produced by fleas. This effect continued through the entire observation period of 35 days.1
