Repellents applied to skin or clothing are generally permitted in carry-on baggage within liquid limits and in checked baggage. Self-defense sprays like pepper spray are strictly prohibited in the cabin and limited in checked luggage. Bear sprays and larger animal repellents are typically forbidden due to their size and potency.
