What type of pesticide is designed to control pests by emitting gas?

  1. Herbicide

  2. Insecticide

  3. Fumigant

  4. Repellent

The correct answer is: Fumigant

Fumigants are specifically designed to control pests by emitting gas. This unique characteristic allows them to penetrate spaces that are otherwise difficult to treat with traditional liquid or solid pesticides. Fumigants are often used in scenarios such as soil treatment, stored grain, and building disinfestation, where a broad-spectrum approach is necessary and pests may be hiding in inaccessible areas. By converting into a gas, these pesticides can effectively reach and eliminate a variety of pests, including insects, rodents, and fungi, ensuring comprehensive pest management. This gaseous form enhances their ability to infiltrate and act in enclosed environments, making fumigants a powerful tool in pest control practices.
