I have used Fleabusters for over 10 years. It is a natural powder that you dust on floors, furniture or anywhere there is infestation. After dusting you brush it slightly and it disappears. The powder adheres to the pet’s hair simply by being in the environment that has been dusted. It is a natural remedy and harmless even to crawling babies. You can have it professionally applied or dust it on yourself. It lasts until you shampoo the surface. For more inro log on to fleabusters.com You will be glad you did.
