Made from cinnamon, cedar wood and clove oils, this long-lasting natural spray works to defeat fleas, ticks, black flies and mosquitoes on contact. The unique formula softens the waxy exoskeleton of pests, making them vulnerable to the botanical extract agents—and, even better, parasites can’t become resistant so the treatment never loses its effectiveness. Safe for dogs of all ages, this non-toxic mist remains fully effective against fleas for up to 7 days for optimum protection!
