Will the immobilized parasites fall off the coat immediately?

The parasites that come into contact with Dimethicone, will often fall from the coat immediatel. However, it can also occur that they remain in the coat for a while longer. Since the parasites have been immobilized by the Dimethicone, they will no longer be able to bite/sting. By brushing the coat, the parasites can easily be removed from the animal.
