When you're hitting insect infested areas and you need maximum protection, turn to Ben's 3. 4oz 100 Max Tick Insect Repellent Pump Spray, offered by Adventure Medical. 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, and small enough to be allowed in your carry on if you're traveling by plane.
