The Invisible bug barrier of Bullseye is an IR3535 that goes on dry and is scent free.
This product compares to Skin so Soft, which I have been using for years on myself, kids and pets.
Super effective and mild enough for everyday use. IR 3535 being what you are looking for. What is nice about the Bullseye is it is goes on dry and is scent free.
Have taken this out on three longish hikes in the woods of the Blue Ridge Mountains. Works as advertised! No ticks and no mosquitoes bugging me whatsoever.
