When we're hitting insect-infested areas and we need maximum protection, we turn to Ben's 100 Max Tick & Insect Repellent. It is 100% DEET, with no fillers to dilute its effectiveness, and its fragrance-free formula keeps the bug-spray smell to a minimum. A single application lasts up to ten hours, and the 3.4-ounce bottle size is large enough for bigger groups or extended trips while staying small enough to be allowed in our carry-on when we travel by plane.100% DEET for maximum protectionSingle application lasts up to ten hoursMaximum TSA-approved carry-on size Volume3.4ozApplicationspray-onIngredients100% DEETManufacturer WarrantylifetimeActivitycasual, weekend camping, hiking
