Kiltix gives your dog fast acting, long term tick control. Kiltix controls Brown Dog and Bush Ticks for up to 5 months. It also aids in the control of deadly Paralysis Tick for 6 weeks. Kiltix collars contain the active ingredient flumethrin. Regarded as one of the world’s most effective tick killing treatments, flumethrin has a long and successful history in livestock tick treatments. Flumethrin not only kills ticks, it repels them. Known as the “hot foot” effect, ticks are repelled before they have the chance to attach to your dog. Kiltix collars work by releasing the flumethrin from the collar as a fine powder which is distributed around your pet’s body as it moves.
