Which class of pesticides is least toxic to humans and animals?

Class IV pesticides are recognized as the least toxic to humans and animals. This classification is part of a system created for labeling pesticides based on their toxicity levels. Class IV pesticides pose minimal risk and are generally considered safe for application, even in scenarios where there is direct exposure or where they may impact non-target organisms, such as beneficial insects, wildlife, or domestic animals.

This classification is important for guiding users toward safer pest management practices and encourages the use of substances that are less harmful, which aligns with the principles of Integrated Pest Management (IPM). Thus, utilizing Class IV pesticides can reduce health risks and promote a safer environment while still helping to manage pest populations effectively.
