Protecting our Nation’s food, farms, and natural resources from invasive pests is a top priority. From monitoring and prevention to rapid response, USDA works to stop pests before they spread.

How USDA Is Fighting Hungry Pests

Across the Country and Around the World

From stopping pests at their source overseas to monitoring outbreaks here at home, USDA fights hungry pests on multiple fronts.

To stay ahead of threats at home, we work with other countries to stop pests at the source.

Key efforts include:

  • Supporting international pest detection, control, and eradication programs. For example, we work with Mexico and Guatemala to contain and eliminate the Mediterranean fruit fly before it reaches the United States.
  • Inspecting certain U.S.-bound exports to ensure they are pest- and disease-free before departure.
  • Helping countries strengthen systems to safely export agricultural products to the United States.

Stopping pests at our borders is a critical line of defense. We work with global partners and support inspections at U.S. ports of entry.

Key efforts include:

  • Developing international, science-based standards through the International Plant Protection Convention. For example, wood packaging materials must be treated and marked to prevent the spread of invasive insects.
  • Supporting agricultural inspections at U.S. ports of entry conducted by the U.S. Department of Homeland Security.
  • Preventing the entry of smuggled agricultural goods.

Across the United States, we work with State partners to detect, control, and respond to invasive pests—and to keep the public informed.

Key efforts include:

  • Conducting nationwide surveys each year to detect invasive pests early.
  • Responding rapidly to outbreaks to limit agricultural, environmental, and economic damage.
  • Educating the public about invasive species and how to prevent their spread.

How You Can Help

Here are ways you can take part in preventing the spread of invasive pests:

  • Learn how pests spread—and how to stop them. Small actions can make a big difference.
  • Report what you see. Use our pest directory to help identify a pest and find reporting guidance on each pest page.
  • Connect with your local USDA office for help identifying pests, reporting concerns, or understanding restrictions on moving plants and plant products.

To report a pest or disease, ask about programs in your State, or learn about moving plants or plant products, contact:

State Plant Health Directors

Contact your local APHIS plant health director. They can help identify pests, answer questions about pest management and eradication programs, and explain any restrictions that may apply in your State.
