In coastal and suburban communities like Leland, weed killer exposure frequently traces back to:
- Residential lawn care (store-bought products used seasonally)
- Professional landscaping or pest services
- Shared or adjacent properties where application happens near sidewalks, fences, or common paths
- Family exposure inside the home after residues are tracked on shoes or clothing
Because these scenarios are common, the early documentation that helps most is also practical: photos, product labels, dates of use, and a clear medical timeline.
