FRONTLINE Brand Products make fleas hyperexcited, drawing them to the top of the haircoat before dying. This will make them more visible to you. Q. I treated my pet with a FRONTLINE Brand Product, but I still see fleas in my home. Why? A. The fleas you see are most likely hatched flea eggs that were deposited in the environment before you began using FRONTLINE Brand Products. Consecutive monthly applications of a FRONTLINE Brand Product to your pet will assist with the elimination of an indoor flea life cycle. In some geographical regions in the United States, it may be required to use the product year-round. Q. How long after application can my pet be bathed or go swimming? A. FRONTLINE Brand Products remain effective for 30 days, even if a pet swims or is bathed. After application, keep the dog from getting wet until the application area appears dry, usually 24 hours.
