We use Frontline with Mikey. He was infested with fleas and had several ticks on him when we got him. We put the Frontline on him and 24 hours later everything was gone. His crate was full of dead fleas. I was glad to see all of the dead fleas, then I didn't have to worry so much that they had just jumped off and where going to live in the carpet. I am pleased with the results.
