FDA Authorizes CLiK Extra Wound Spray to Help Prevent New World Screwworm in Multiple Species

FDA issued an Emergency Use Authorization for CLiK Extra dicyclanil wound spray for prevention of New World screwworm myiasis associated with wounds, birth, and certain husbandry procedures in sheep, cattle, goats, swine, camelids, and specified captive or captured wildlife species. CLiK Extra is authorized for prevention in defined species and situations; established infestation requires veterinary treatment rather than simply applying a preventive product. This is educational context rather than a reason to diagnose a pet or change treatment without veterinary guidance.
