The most important thing about fleas is that they're very hard to control. Once they get in your home, it's really bad. They come in three stages, and when an adult flea bites your dog or cat, it will lay somewhere in the neighborhood of 500 eggs a day. Those eggs turn into a form called the pupa, and they fall off of your dog or cat and go into your carpets and upholstery, and they're almost impossible to get rid of. You really have to use a professional to resolve fleas in your home.

Fleas and ticks are easily preventable with prescription products. There are no specific non-prescription products that I'm familiar with that work effectively. In fact, I've seen them all fail.
