In Baltimore—especially for people living in row homes, maintaining small yards, working near active landscaping schedules, or commuting through neighborhoods where properties are treated—exposure can be complicated. Products may be applied by:
- a homeowner or family member on a routine schedule,
- a contracted lawn/landscaping crew,
- a property manager for multi-unit buildings,
- or even as follow-up treatment after initial application.
Because Maryland residents often encounter routine residential landscaping and ongoing property maintenance, investigators typically focus on reconstructing application patterns rather than relying on a single “one-time” event.
What to consider right now:
- Did the treatment happen around the same time symptoms began to show up?
- Were you present when the product was applied, or were you affected afterward (spray drift, residue, tracked-in material)?
- Do you have any proof of what was used (label photos, receipts, product names, or even a container stored in a shed/garage)?
