Diazinon is an organophosphate insecticide. Pesticides in this chemical family work by blocking an enzyme in the nervous system that acts as a stop switch for a nerve signal. If the enzyme is blocked, the nervous system can't work properly and eventually it fails. Diazinon is used in agriculture but it is no longer registered for residential use.
If you have questions about diazinon, or any pesticide-related topic, please call NPIC at 1-800-858-7378 (7:30am-3:30pm PST), or email at firstname.lastname@example.org.
