Which statement about repellants is true?

• A. They deter pests from approaching an area without killing them
• B. They kill pests on contact
• C. They attract pests away from treated areas
• D. They sterilize pests

Answer: (A)

Repellents work by creating cues that pests perceive as undesirable, so they avoid treated areas instead of being killed. This creates a protective buffer that reduces entry or contact with the treated zone. They’re not designed to kill on contact, so that rules out killing actions. They also don’t attract pests away; that would be the job of attractants or decoys. And sterilization is a separate control method aimed at reducing reproduction, not avoidance. In practice, repellents help keep pests out of places you want to protect, without harming them directly.
