Budget: Burt Bees

Natural Insect Repellent Suggestions

Just wondering if anyone has had luck with any natural (non-chemical) insect repellents. I'd like to not spray my children with chemicals, but if I don't we get eaten alive! Also, I've been trying Burt's Bees with some success (less bites than using nothing, but still getting bites), so I thought I'd see if there's anything better out there. Thanks! B.
