What term describes pesticides used to deter pests from approaching an area, without killing them?

• A. Repellants
• B. Insecticides
• C. Fungicides
• D. Rodenticides

Answer: (A)

Repellents are pesticides designed to discourage pests from approaching or staying in an area rather than killing them. They work by creating an unattractive cue—such as an odor, taste, or other deterrent—that makes the treated area less appealing. This approach is useful when the goal is to reduce pest activity while minimizing harm to people, pets, or non-target wildlife, and it can be applied around homes, gardens, or crops. Because the deterrent effect can fade or pests may habituate, repellents often require reapplication or renewal of the barrier. In contrast, insecticides, rodenticides, and fungicides are formulated to kill pests or pathogens, not merely deter them.
