Hi Laila, My vet told me that Head & Shoulders ( the human shampoo) was a great way to get rid of fleas on ferrets without harming them, their are other safe methods, that one just stuck in my head!! I doubt that it kills eggs although I don't know for sure but it will kill the fleas and it doesn't sound like yours has a huge flea problem so you might want to give it a try! Good luck..
