When a local resident discovered a large stand of unfamiliar plants taking over the back of her property, she reached out to her county Extension agent for help. The agent quickly identified the plant as poison hemlock (Conium maculatum), a toxic invasive species that poses serious risks to people, livestock, and wildlife. Recognized by the USDA as part of its invasive species advisory list, poison hemlock spreads aggressively and is increasingly common across the region.

The Extension agent met with the homeowner to develop a safe and effective eradication plan. Together, they implemented a combination of targeted herbicide application and mechanical removal, while taking precautions to avoid skin contact or inhalation of plant particles. Within the season, the infestation was under control, and the homeowner could reclaim the use of her property.

The agent’s work didn’t stop there. Knowing that invasive species control is most effective when the whole community is involved, the homeowner and Extension agent organized an informal neighborhood walk. Neighbors learned how to identify poison hemlock by its fern-like leaves, purple-speckled stems, and umbrella-shaped clusters of white flowers. They also received guidance on safe removal methods and how to prevent the plant from spreading.

Today, not only has the original property been cleared of poison hemlock, but nearby landowners have also taken proactive steps to inspect and manage their own land. Through hands-on assistance, community education, and USDA-backed resources, the Extension agent turned a single call for help into a community-wide success story in invasive plant management.
