Which statement describes dusts?

• A. Liquid suspensions designed for fogging.
• B. Dry materials made of active ingredient and inert substances.
• C. Granular pellets used for baiting.
• D. Pressurized aerosols for surface coating.

Answer: (B)

Dusts are dry, powdery pesticide formulations that combine an active ingredient with inert substances to carry and distribute the chemical. This setup enables the product to stay as a fine, dry coating on surfaces and in voids, where crawling pests contact it directly or pick it up on their bodies. The inert carrier helps control particle size, flow, and distribution so the dust can be applied into cracks and crevices and remain where it’s needed for residual action. Other statements describe different product forms. Liquid suspensions designed for fogging are liquids used to create a fog, not dry powders. Granular pellets used for baiting are bait formulations intended to attract and feed pests, not dusts. Pressurized aerosols for surface coating are spray forms that disperse droplets, not dry powders. So, describing dusts as dry materials made of an active ingredient and inert substances captures their defining characteristics and how they’re used in pest control.
