Where It Comes From
Professional pest-control products and treatments in buildings; use and approvals vary by country [1].
How You Are Exposed
Breathing spray mist, skin contact during application, touching treated surfaces or dust and then hand-to-mouth, and occupational handling; food or water are less common routes for this mainly indoor-use pesticide [1][3].
Why It Matters
Can cause headache, dizziness, nausea, sweating, and pinpoint pupils; high exposures may lead to breathing trouble, seizures, or even death. Repeated exposure can depress blood cholinesterase. WHO classifies propetamphos as moderately hazardous (Class II) [2][3].
Who Is at Risk
Pest-control workers; people present during indoor treatments; young children who crawl and mouth surfaces; and individuals who are pregnant or have asthma or reduced detox enzymes may be more sensitive [2][3].
How to Lower Your Exposure
Prefer integrated pest management (seal entry points, clean up food/water sources). If treatment uses propetamphos, leave during application, ventilate well, and keep children/pets away until dry. Always follow the label; wear gloves; wash hands and work clothes separately. Workers may need routine cholinesterase testing [1][3].
