In Henderson’s residential neighborhoods and planned communities, it’s common for properties to be landscaped, retreated, or resold multiple times over the years. That can make exposure proof tricky when you’re dealing with:
- Yard or driveway re-treatment after symptoms appear
- Discarded product containers during spring cleanup
- Landscaping contractor turnover (and records that never get retained)
- Changes in who lives in the home after an illness begins
The sooner you preserve what you can, the better your odds of reconstructing a believable timeline—even if the exact bottle is no longer available.
