Pesticides: Diazinon use & disposal

Diazinon is a potent pesticide used to control insects such as aphids, yellow jackets, ants, roaches and silverfish. It is widely available and sold in a variety of concentrations under several trade names.

While Diazinon is generally safe when used as directed, it is classified as a moderately toxic or slightly toxic chemical, depending on the formulation used. Products with Diazinon in them must carry the signal words "WARNING" or "CAUTION." In humans, Diazinon poisoning affects the central nervous system.

To properly use and dispose of Diazinon, follow these five steps. First, buy the smallest amount needed for the job at hand. Next, mix and use the product as directed on the label. Third, use the entire solution you have prepared. Fourth, triple-rinse the empty container and sprinkle the rinse water in your yard or pour the rest into an absorbent material like cat litter. Finally, wrap the empty and rinsed container and the absorbent material in newspapers and put it in the trash.

NEVER dispose of leftover Diazinon in any formula or dilution by dumping it down a sink, toilet, sewer or storm drain. Even a small amount of Diazinon can contaminate millions of gallons of wastewater. While wastewater is treated and cleaned to very high standards before it is returned to the natural environment, there is no known method for neutralizing Diazinon once it is in the waste disposal system.

If Diazinon is dumped into the sewer system or down a storm drain, it stays in the water. For example, this waste goes back into a river and kills aquatic creatures and causes additional harm to the environment.

If you choose to use a product containing Diazinon or any hazardous chemical in your home or Garden, use it properly, in the correct amounts and dispose of the container safely.
