Certain ticks and flies (also called vectors) can injure and transfer disease to people and animals and threaten American agriculture. APHIS has put in place measures to prevent the entry, establishment, and spread of exotic vectors. These safeguards include import inspections, testing, identification, surveillance, and targeted response and treatment strategies.
