We put the Insect DEFEND Patch on before driving up to the cottage, approximately 2.5 hours and got attacked when we stepped out of the car. Why?
The release of Vitamin B1 into the body works when the body is in motion. Try applying the patch before you start loading the vehicle and allow a little time after arriving (about the time needed to empty the vehicle) to best judge the results. This activity will result in the body’s chemistry reacting with the vitamin B1 to produce an ‘invisible barrier’.
