Fumigants are chemicals that are used to kill pests by releasing a gas that penetrates into areas where pests may be hiding. These chemicals are often used to control pests in large, enclosed spaces such as grain storage facilities or ships.
Pesticides, on the other hand, are chemicals that are used to control, repel, or kill pests. Pesticides can be applied in various forms, such as liquids, granules, or sprays, and can be used to control pests on crops, gardens, and other outdoor areas.
One natural substance that can be used in place of a fumigant is thyme. Thyme is a herb that contains a chemical called thymol, which has insecticidal properties. Thymol can be used to control a variety of pests, including mites, insects, and nematodes. It can be applied in various forms, such as a spray or a dust, and is considered to be less toxic and safer to use than synthetic fumigants.
