The DefendPatch is 100%
DEET FREE, safe and natural.

Research has shown that Thiamine (Vitamin B1), the key ingredient in the patch, when topically applied, actually helps repel insects like mosquitoes and flies. The thiamine-based formulation of DefendPatch works with the body's own chemistry to create an invisible protective "barrier" that shields the user from mosquitoes and other biting insects. DefendPatch contains no pesticides (like DEET, which is not considered safe for children) and with still unknown but potentially adverse effects on health. DefendPatch is totaly safe and approved for use in chidren as young as one year of age.
