Where should pesticides generally NOT be applied?

Pesticides should generally not be applied on railings and doorknobs due to the potential for human contact. Surfaces like these are frequently touched by people, which increases the risk of exposure to harmful chemicals. Using pesticides in such areas poses health risks not only to people but also to pets and wildlife, as residues can be transferred to hands and other surfaces, leading to unintended ingestion or absorption of harmful substances.

In contrast, the other settings, such as agricultural fields, storage areas, and gardens, may be appropriate for pesticide use when applied correctly and according to safety guidelines. These areas typically involve controlled applications designed to minimize exposure and maximize effectiveness against pests.
