Which pesticide is used to control slugs and snails?

• A. Insecticides
• B. Rodenticides
• C. Molluscicides
• D. Growth regulators

Answer: (C)

Slugs and snails are mollusks, so they require a pesticide classified to target mollusks. Pesticide labels specify the pests each product is meant to control, and molluscicides are the type designed to kill or deter mollusks. Insecticides target insects, rodenticides target rodents, and growth regulators affect development rather than acting as a direct mollusk killer, so they aren’t appropriate for slug or snail control. Using a product not labeled for mollusks won’t effectively control them and can be noncompliant with label directions and regulations. Common molluscicides include iron phosphate and metaldehyde-based baits, used according to the label to minimize risks to people, pets, and non-target wildlife. Always choose a product labeled for mollusks and follow Alberta pesticide safety guidelines and regulations.
