Which pesticide would be used to control slugs and snails?

The correct choice for controlling slugs and snails is the substance known as molluscicides. Molluscicides are specifically formulated to target and eliminate mollusks, which include not only slugs and snails but also other similar soft-bodied creatures. The active ingredients in these pesticides are designed to interfere with the physiological functions of mollusks, effectively managing their populations in agricultural and gardening settings.

Herbicides are intended for managing unwanted plants or weeds, making them ineffective against slugs and snails. Piscicides are used to control fish populations and have no application in managing land-dwelling pests like slugs. Rodenticides are formulated to target rodents, and while they might mimic the appearance of some pest control methods, they do not address the specific issue of mollusk management. Therefore, the use of molluscicides is the most effective and appropriate choice for controlling slugs and snails.
