Identifying and Safely Removing Poison Oak

Photos of two upright, 7-inch seedlings in shade were confirmed as poison oak (Toxicodendron diversilobum or related species). The classic "leaves of three" pattern and glossy leaflets are key identifiers.

Safe Removal

1. Wear disposable gloves, long sleeves, and eye protection.
2. Pour a small amount of glyphosate (Roundup) into a disposable container.
3. Using a paintbrush, carefully apply herbicide to the leaves—avoid drift onto desirable plants.
4. Dispose of gloves and brush; wash skin thoroughly with soap and cool water.

Spot-treating minimizes chemical use and protects surrounding plants. Monitor for regrowth and repeat as needed. Never burn poison oak—smoke carries urushiol oil and can cause severe respiratory reactions.
