The Word ضد

Forming Resistance Adjectives

To describe a product that fights termites (موریانه), bedbugs (ساس), or fleas (کک), simply add ضد before the pest's name.

This structure is highly productive and works for any noun you wish to repel or defend against, from rodents (جونده) to moths (بید). Because the resulting phrase functions as an adjective, it usually follows the noun it describes (such as "poison" or "trap"), linking to it with the ezafe.
