It's absorbed through the dog's skin into the bloodstream, and it kills the tick when they start drawing blood. A deer tick has to be attached for 12-24 hours before it can pass on the Lyme virus. If it was a repellent you'd have to put it all over the dog's coat. You just put the little dab in the packet on the back of the dog's neck where it can't lick it off.
It's actually a pesticide, not a repellent.
