Should a duster be used for multiple pesticides after it has been used for one?

A duster should not be reused for multiple pesticides after it has been used for one due to the potential for chemical residues to mix, which can lead to ineffective pest control or unintended harm to non-target organisms. Each pesticide may have its own unique chemical composition and mode of action, and residues left in the duster from a previous application can contaminate the next pesticide used within the same equipment. This can also create hazards for humans, pets, and beneficial organisms in the environment.

Additionally, certain pesticides may require specific application techniques or have unique properties that necessitate dedicated equipment to avoid cross-contamination. Clean equipment is essential for both safety and effectiveness in pest control practices. Always following manufacturers' recommendations and safety guidelines helps ensure that pesticide applications are both effective and safe.
