What should be done with unused or leftover pesticides?

Unused or leftover pesticides must be handled according to local regulations for safe disposal. This is because each area may have specific guidelines that pertain to the environmental safety, public health, and legal aspects of pesticide disposal. Following these regulations ensures that pesticides do not contaminate water sources, harm wildlife, or pose a risk to humans.

Improper disposal methods, such as putting pesticides in regular trash or pouring them down the drain, can lead to serious environmental consequences and may violate laws. Storing pesticides indefinitely without a plan for their eventual use or disposal can also create safety hazards and is not a recommended practice. Thus, following local regulations is the most responsible and safe approach to managing unused pesticides.
