Repel Camp Lotion for Families with 10% deet. Deet repellents offer a wide and diverse range of products. Active ingredients run from the low single digits up to 100%. An efficiency curve drawn for deet would show that the repellent effectiveness begins to drop off quickly in concentrations above 35% deet. Keep in mind that ALL deet products repel but for various time lines. Lower dosage will equal more frequent application. Normal logic says that more is better, but not for deet. If a 17% product works well for 4 to 6 hours, a 35% product should work for 8 to 12 hours . . . It will not unless micro-encapsulated.
Lower percentages can be considered for pre-adolescent children but always verify this with your own physician.
