This flea collar offers an easy-to-use, topical solution to the pesky problem of dog fleas and ticks. Sentry Pro Flea & Tick Collar for Dogs uses four ingredients including propoxur, phenothrin, and pyriproxyfen to kill adult fleas, ticks, flea eggs and flea larvae. Since 90% of a flea infestation can exist in the pre-adult forms of the flea (egg, larvae, pupae), this collar protects your pet against reinfestation for up to 6 months. Unlike topical formulas that require monthly application, this collar, once properly fitted and placed on your pet, provides continuous protection for up to 6 months. Fresh powdery scent. Made in USA. 1.1 oz (30 g) collar. Fits necks up to 26".
