A single female flea can produce up to 50 eggs a day,1 turning “one little flea” into a full-blown infestation before you even know it's there. Comfortis® (spinosad) for dogs starts killing fleas before they lay eggs and provides a full month of flea protection to help prevent future flea infestations.
And Comfortis is easy to administer!
