Which is an example of a non-chemical pest control method?

• A. Exclusion, sanitation, moisture control, traps, or mechanical removal
• B. Chemical pesticide application
• C. Use of air fresheners
• D. Fumigation with high-dose chemicals

Answer: (A)

Non-chemical pest control relies on preventing pests from entering and removing them without using pesticides. The best example of this approach is a combination of exclusion, sanitation, moisture control, traps, and mechanical removal. Exclusion stops pests from getting inside by sealing cracks, installing screens, and keeping doors and windows well-fitted. Sanitation reduces attractants by keeping areas clean, storing food properly, and eliminating clutter where pests can hide. Moisture control removes water sources that pests need for breeding and survival. Traps and mechanical removal physically capture or remove pests as they appear. Using these methods together lowers pest pressure and often provides safer, longer-lasting results than chemical methods.

Chemical pesticide application and fumigation rely on chemical agents to kill or repel pests, which is why they’re not considered non-chemical methods. Air fresheners don’t address pest populations or entry and thus aren’t effective pest control strategies.
