For pesticides in their original, unopened containers: Dealers and manufacturers will sometimes accept the return of unopened containers of recently purchased pesticides. Contact the manufacturer listed on the product label. If a return cannot be arranged, the pesticide may be donated to someone who is qualified to use it properly. Before donating any pesticide, make sure that you are in compliance with these limitations: the pesticide is not designated RESTRICTED USE on the label; and, the donated pesticide must be in its original, fully-labeled container.
For leftover/excess pesticides in their original container: The label may indicate how to dispose of small amounts of the pesticide. Often, left-over pesticide may be applied to a site permitted by the label. Do not exceed the labeled application rate, and follow all directions. If the pesticide registration was recently canceled or suspended, the manufacturer may have set up a recall program to collect the pesticide for disposal. In general, these canceled products may be used at the user level until the stock is exhausted (see How to Deal with Label Changes).
Clothing worn during pesticide applications should be washed separately from other laundry before reuse. Follow the pesticide manufacturer’s instruction for cleaning/maintaining personal protective equipment, including clothing.
Discard clothing that has been drenched or heavily contaminated with concentrated product. Do not reuse it. Most of this clothing can be discarded as normal solid waste. Bundle it in a plastic bag, label the bag, and take it to a household hazardous waste collection site. Clothing contaminated by pesticides regulated as hazardous waste (see The Law on Pesticide Wastes) must be disposed of as hazardous waste, if it is heavily contaminated as a result of a spill or leak.
