Protect Gardens Now from Invasive, ‘Hungry Pests’

USDA Offers Six, Easy-to-Follow Tips to Help Save Gardens and Landscapes

WASHINGTON D.C., April 5, 2016


With spring’s arrival, now is the time to think about ways to protect gardens and landscapes from dangerous invasive pests. To recognize April as Invasive Plant Pest and Disease Awareness Month, USDA-APHIS (Animal and Plant Health Inspection Service) encourages the public to follow six simple tips to protect their properties from 19 particularly destructive invasive species known as “Hungry Pests” which are primarily spread by humans in the things they move and pack. 


“Gardeners know how to grow and nurture beautiful landscapes and bountiful gardens, and they more than anyone can appreciate the need to protect America's agricultural and natural resources,” said Julie Spaulding, acting director of pest management, Plant Protection and Quarantine, USDA-APHIS. “Unfortunately, invasive species are a real threat, costing our nation $120 billion each year. Because they have few natural enemies here, they can spread without resistance, damaging our crops, trees and plants. Gardeners should be especially careful to protect against invasive species.”


Homeowners can help protect America’s gardens, farms, forests and landscapes by following a few simple tips:


  • Start by only buying plants from reputable sources, such as established nurseries or online businesses. Ask where they buy their plants and if they comply with federal quarantine restrictions. Fly-by-night dealers, whether in your neighborhood or online, may not be doing what is required to keep plants free of invasive pests.
  • Call your local USDA office to find out how to safely dispose of trees, branches or other yard debris. Moving such materials to areas outside your property could spread invasive pests. Make sure any contractors you are working with also follow these procedures. For a list of local USDA offices, visit
  • Don’t move citrus plants or items made with fresh citrus, such as floral arrangements or kaffir lime leaves. That’s how citrus greening – a citrus disease that is killing America’s orange groves – has spread.
  • You may live in an area under quarantine for an invasive pest. Call your local USDA office to find out before moving homegrown produce, plants and plant parts. And to be safe, don’t bring back plants from other areas, including when traveling abroad. That’s how the Mexican fruit fly – which threatens at least 50 types of fruits and vegetables – entered the United States.
  • Look for round and D-shaped holes in trees, especially in the late spring and summer months. They could be the exit holes of Asian longhorned beetles or emerald ash borers. Also look for yellow, thin or wilted leaves, shoots growing from roots or tree trunks, sawdust-like material on the ground or in branches, and unusual woodpecker activity. If you see something that looks suspicious, be safe and report it using the “Report a Pest” button found on the home page of the Hungry Pests website.
  • For those living in the northeast quadrant of the country, inspect lawn furniture, fences, walls and other outdoor items, and remove and immerse gypsy moth egg masses in soapy water. This is especially important before moving outdoor items to areas outside your property. Gypsy moths eat more than 300 species of trees and shrubs, including fruit trees. Early detection is key to controlling them, so report findings to federal or state agricultural officials.
