What is the main function of repellants in pest management?

The main function of repellents in pest management is to repel insects and other pests. Repellents are chemical or natural substances designed to cause insects or pests to avoid certain areas or treated surfaces, effectively preventing them from feeding or nesting in those locations. This function is crucial in integrated pest management strategies as it not only helps protect crops or stored products from damage caused by pests but also reduces their populations over time without necessarily killing them.

By deterring pests, repellents can minimize the need for more aggressive control measures, such as pesticides that kill insects, which can have broader environmental impacts. The formulation of repellents can vary widely, and they are commonly used in agriculture, gardening, and even personal protection to reduce encounters with harmful insects. Thus, repellents play an important role in maintaining healthy ecosystems while managing pest threats effectively.
