There are many different types of flea treatments, but the best one for you depends on your individual situation. For example, if your pet has a flea infestation, then you will need to use a treatment that kills both adult fleas and eggs. If you only have a few fleas, then an over-the-counter treatment like Advantage or Frontline may be enough. You also need to consider the environment in which your pet lives. If there is a lot of carpeting or other places where fleas can hide, then you may need to use an indoor/outdoor treatment like K9 Advantix II.

The best flea treatment is a product called Frontline Plus. It's a liquid that you put on your pet's skin and it kills the fleas and ticks. There are also other very good products available, such as Revolution and Advantage, but I would recommend Frontline Plus over any of them.
