I need to ask an important medical question? Is anybody allergic to deet? Is picardin safer for everyone?

DEET versus Picardin. Deet allergy can occur but is very rare. Concentrations of any repellant above 50% are not more effective than the 50% concentration and can be irritating. Picardin is considered an effective alternative to deet. Also, can consider using Permethrin treated clothing, shoes, bed nets, sleeping bags, etc.
