Which pesticide type is known to be non-selective and kill a variety of pests?

Fumigants are a type of pesticide known for their ability to be non-selective and effective against a broad range of pests. They are gases that penetrate soil or structures to eliminate pests, including insects, nematodes, and even pathogens like fungi and bacteria. This characteristic makes fumigants particularly useful for treating large infestations or areas where a comprehensive solution is necessary.

Their method of action allows them to reach pests that may be hidden or embedded in materials, making them distinct compared to other pesticide categories, which may have more specific targets.

While herbicides are designed primarily to kill unwanted plants, systemic pesticides target specific pests within plants, and contact insecticides usually act on surface insects. Therefore, these other types of pesticides are more selective, either targeting specific organisms or limiting their action to a certain type of pest.
