In coastal Central California communities like Morro Bay, herbicide use often shows up in predictable places:
- Property maintenance around homes and rentals: repeated weed control for driveways, fences, patios, and landscaped areas.
- Public-facing businesses: landscaping contractors servicing restaurants, storefronts, and visitor areas.
- Parks, pathways, and coastal lots: maintenance schedules that can leave residue on surfaces and vegetation.
- Secondhand exposure: residue carried on work boots, clothing, or tools after yard work or contractor visits.
People sometimes assume exposure requires mixing or spraying themselves. In reality, many Morro Bay residents first learn to connect the dots only after a diagnosis—when they start reviewing past yard work, contractor visits, or time spent in treated areas.
