I have always used the Advantage products. Gracie is on Advantage II during flea season. I have heard that Bio Spot is a waste of money. Advantage II has been working great. If you have fleas inside you need to treat the home by vacuuming on and under every bit of furniture and floor surface and washing all bedding. One flea can lay thousands of eggs in your home and the darn things hatch! When your dog is being inundated with fleas even the best flea preventative will not last the full month and will need to be reapplied sooner. It's not recommended to keep doing that though. It's best to do everything you can to get rid of fleas and eggs in the home and then your pet won't have them jumping on him anymore. |
