What does the term "repellent" refer to in pest control?

In pest control, the term "repellent" specifically refers to a substance designed to deter pests from entering treated areas. This is accomplished by creating an unpleasant environment for the pests, which makes them avoid the area instead of simply eliminating them. Repellents work by masking scents that attract pests, utilizing odors that are offensive to them, or creating physical barriers that prevent access.

Understanding the function of repellents is crucial in integrated pest management, as they play a significant role in prevention strategies. Unlike pesticides that kill or trap pests, repellents focus on keeping them away from specific areas, making them a valuable tool for reducing pest populations before they can establish themselves indoors or within a given environment.

The other options, while related to pest management, describe different approaches that do not align with the specific definition of a repellent. Recognizing this distinction helps pest control professionals effectively utilize various strategies for managing pest issues.
