How does long lasting flea medicine work?
How does long lasting flea medicine ( like Advantage) kill the fleas and their eggs for a month without hurting the dog or cat?
If I haven’t used this on my dog before I wouldn’t have a box that has directions inside.

Wash the dog with Prell shampoo, let it sit on 5 – 10 minutes. Then follow directions with Advantage. The problem with fleas is that only about 25% are on the dog. The rest are in your house. They only stay on the dog to feed than jump off onto your carpet, couch, bed etc. You got to "bomb" the house at least twice, right away and then a few weeks later. First one kills anything that has hatched but not the eggs. Second one gets the eggs that have now hatched.
