Many Santa Rosa cases begin with a familiar routine:
- Using weed killer at home—driveways, patios, fences, and landscaping beds.
- Hiring or relying on local lawn/landscape services that apply herbicides on schedules.
- Being in the same areas repeatedly (near a back fence, HOA common areas, or a nearby property) while applications are happening.
- Working outdoors or commuting through areas where vegetation is regularly managed.
What’s frustrating is that the exposure often doesn’t feel “event-like.” People may not save bottles, may not note application dates, or may only remember the product by brand name—later, when a diagnosis changes everything.
