In many Stockton households and nearby neighborhoods, weed control tends to happen year-round—driveways, backyards, side yards, rental properties, and HOA-managed common areas. That routine can make exposure hard to pinpoint later because:
- product bottles are disposed of after a season,
- labels fade or are lost,
- application dates blur (especially when multiple family members help), and
- symptoms show up months or years after exposure.
When that happens, the difference between “maybe” and “provable” usually comes down to documentation you can still reconstruct.
