Lice are less common in Australia these days as many of our commonly used insecticidal products readily kill lice. However, they are still found sporadically and can cause skin disease. Most good quality flea products will also kill lice. A common sign of lice can be a white flake, which if inspected closely ‘moves’. This should not be confused with the dandruff caused by many skin infections with bacteria or yeast which can cause the skin surface to flake off as it gets damaged.
