Every April, the USDA shines a spotlight on one of the most persistent threats to American agriculture — invasive pests. From destructive beetles to fast-spreading plant diseases, these uninvited guests cost the U.S. economy billions of dollars each year in crop damage, lost revenue, and increased management efforts.
That’s why April has been designated Invasive Plant Pest and Disease Awareness Month — a national call to action for farmers, gardeners, and communities to work together in safeguarding the health of our crops, forests, and ecosystems.
Invasive pests are non-native organisms that enter a new environment and cause harm to agriculture, the environment, or even human health. Because they often arrive without natural predators, they can multiply rapidly and overtake native species.
Some well-known examples include:
These pests don’t just affect large-scale farmers — even small home gardens and local forests can become targets, making this everyone’s concern.
While federal and state agencies play a big role in pest control and biosecurity, farmers are the first line of defense. Here’s how you can take action:
Know which invasive species are a threat in your region. State agricultural departments and the USDA provide updated lists and photos. Regularly inspect your fields, orchards, or greenhouses for unusual signs like wilting, leaf discoloration, or unexpected insect clusters.
Early detection is key. If you spot something suspicious, contact your local extension office or use the USDA’s Hungry Pests online reporting tool. Submitting photos and samples can help experts confirm and contain threats before they spread.
Many pests hide in wood, soil, and plant materials. When transporting equipment or selling produce, make sure everything is clean and pest-free. Avoid bringing non-native plants or trees onto your farm without checking for potential risks.
Your farm staff are your eyes in the field. Teach them to recognize signs of invasive pests and how to report them. Encourage them not to ignore unusual patterns — small signs often point to big problems.
Limit foot traffic in sensitive areas, sanitize tools and equipment regularly, and create barriers to stop pest spread between fields. These simple habits can prevent major infestations.
By taking these steps, farmers not only protect their own land but contribute to a nationwide effort to keep America’s food supply secure. April’s Invasive Pest Awareness Month is more than a reminder — it’s a moment to unite science, community, and daily vigilance in defense of agriculture.
After all, one overlooked pest can cause a season’s worth of damage — but one alert farmer can stop it in its tracks.
