Equi-Spot Stable Pack is a topical liquid formula built around permethrin, applied directly to a horse's coat in small, pre-measured spots rather than sprayed over the whole body. Each tube is opened by snapping off the narrow end, then the solution is placed at specific points on the head, neck, back and legs so it spreads across the body surface. The formula is designed to resist washing off during rain or heavy sweating, so a single application continues working for about two weeks before the next tube is needed. The stable pack groups several individual applicator tubes together in one box so repeat treatments are on hand without separate purchases. No mixing, dilution or extra equipment is required; the tube itself doubles as the application tool and is discarded after use. Hands should be kept away from the eyes and mucous membranes of the horse during application, and the label should be reviewed before each use for full directions.
