It's important to remember that dips and baths don't really work that well to kill fleas. They will only kill the fleas on the pet and will work for about the next 24 hours but then they stop working. New fleas are hatching in the environment every day (and then getting on Penny) so you need a product that will be continuously acting. If you must use an over the counter product, try Frontline. There are some resistance issues in the flea population to over the counter products but they still work well in most cases. There are also much better products carried by your veterinarian. Top products for dogs are oral products such as Simparica and Nexgard. Top products for cats are topicals such as Revolution and Cheristan. There is also an oral product called Comfortis that both dogs and cats can take. You will need to switch all the pets over to a good flea product. Make sure to discuss these products with your veterinarian first. These products are generally safe for all pets but there are some conditions which are contraindicated for the oral products. Cleaning up and treating the house and yard will also help but it will not clear all the fleas. The main control is making sure the pets are on good products. This is what will ultimately stop the infestation. Also remember every female fleas lays about 50 eggs a day and it could take up to 6 months before the eggs hatch. Therefore, you will need to treat for at least 6 months. Best of luck and please feel free to post any additional questions.
