FAQ #4 - Does the patch still work if we all go swimming with it on or do we need to re-apply after coming out of the water?

The greatest advantage to using the Insect DEFEND Patch as a means of protection against biting insects is that it continues to work using our bodies own chemistry regardless if we perspire or participate in any water related activity – including swimming. The adhesive qualities of the ‘Patch’ keeps it in place even when it gets wet, (be sure to follow all instructions when applying), and continues to be effective for the full 24-36 hours as the Thiamine (Vitamin B1) continues to be transferred into the bodies epidermal layer.
