How often should I use Scratchex® Dog Stripe-On® Flea and Tick Control?
It is recommended that Scratchex Stripe-On be applied monthly. If you live in an area where ticks and mosquitoes may also potentially be biting your dog, Scratchex® Dog Stripe-On® Flea and Tick Control may be reapplied as often as once every three weeks for maximum protection, or after shampooing your dog.
