A. You can use Nexgard after Frontline. When treating a flea infestation, it is important to treat the environment as well. Vacuum all areas and dispose of the bag outdoors. Wash all fabrics and beddings that have had contact with any pet in the hottest water temp allowable. Knockout Area treatment (by Virbac) is just one very effective product that provides lasting protection against fleas and larvae in the environment. Lastly, treat all pets for tapeworm since fleas carry the risk of tapeworm infection. If you purchased your Frontline from your vet, you can contact Merial at www.frontline.com and take advantage of their Guarantee.
