The flea and tick shampoo is better than fish soap. BUT there are much better ways to treat fleas. So when you give Lunar Moon a bath, you are only killing the fleas that are currently on her and the ones that will jump on her within the next 24 hours, then it wears off. Female fleas lay 50 eggs every single day and these eggs will hatch in 3 to 6 months. So every day you have new fleas hatching out in the environment. A better method to get rid of the fleas are to treat every single pet in the house with a reputable flea product. I recommend Simparica or Nexgard for most dogs. If you want to stick with an over-the-counter product, stick with frontline. Keep in mind though that frontline is now an older product and fleas are developing an immunity to it which means it may not work as well. Environmental cleanup will help with the problem, but it will not illuminate every single flea egg. You must treat for a solid six months in order to get through the whole flea lifecycle. I hope this is helpful and please feel free to post any additional questions!
