Research has found that mosquito sprays and lawn pesticides can drift onto neighboring properties, settle into household dust, and wash into waterways through rain and runoff.
75% of neighboring yards adjacent to professionally sprayed properties tested positive for pyrethroid contamination after mosquito treatments.
Golf courses and heavily treated turf areas have raised concerns, too. A 2025 study found people living within 1 mile of a golf course had more than double the odds of developing Parkinson’s disease compared to those living farther away, with researchers pointing to pesticide-contaminated groundwater as one possible factor.
Even if you choose organic lawn care for your own property, exposure can still happen through drift, runoff, contaminated water, and residue tracked indoors.
