What kind of pesticide is used to kill snails and slugs?

The use of a molluscicide is specifically targeted towards controlling snails and slugs. Molluscicides are designed to affect the physiology of these organisms, typically by disrupting their biological functions or causing dehydration. This is particularly important in agricultural and horticultural contexts, where snails and slugs can cause significant damage to crops and plants.

In contrast, insecticides are formulated to target insects and their specific biological systems, making them ineffective against mollusks. Herbicides focus on killing unwanted plants, which would not address the issue of snails and slugs. Rodenticides are targeted towards rodents and would not provide any control over mollusks either. Thus, the classification of molluscicides makes them the appropriate choice for managing snail and slug populations effectively.
