Ben's brand pump spray repellents contain DEET, the most effective tick and insect repelling ingredient ever developed. Water has replaced alcohol in Ben's 30. Water does not evaporate as quickly as alcohol, and does not open the pores, so the need to frequently reapply the repellent is reduced. Thus, Ben's 30 is an appropriate choice for protecting children as well as adults and it leaves more insect repellent on the skin so that it fights against biting insects longer.
