(Farnam) Bio Spot Defense Flea and Tick Spot On for Cats kills adult fleas, flea eggs, flea larvae, plus deer ticks and mosquitoes on your cat or kitten. Provides relief from flea infestations for up to 30 days. Contains Etofenprox and (s)-methoprene, plus a natural coat conditioner. Bio Spot Defense comes with a Smart Shield Applicator, which is specially designed to make applying flea and tick control easier, more precise, and neater than ever before. You simply insert the appropriate tube for your cat/kitten into the applicator, close it and squeeze to apply. The applicator’s ergonomic, contoured shape makes it easy to grip and a built-in fin helps to spread the cat’s hair to allow the liquid to more readily reach the skin. The tube is sealed inside, so you can be confident that the liquid goes onto your cat, and not your hand. Do not use on kittens less than 12 weeks of age. Do not reapply more often than every 30 days. Do not get in cat’s eyes or mouth.
