Used as a systemic insecticide in agriculture and horticulture, it controls sucking insects like aphids, whiteflies, and leafhoppers. Applied to soil, seeds, or foliage, it is absorbed by plants and distributed through the vascular system, providing long-lasting protection. Commonly used on crops such as cotton, rice, vegetables, and ornamental plants. Also found in pest control products for residential use, including treatments for termites, cockroaches, ants, and flea control on pets. Effective at low concentrations due to high affinity for insect nicotinic acetylcholine receptors. However, its use requires caution as it may affect non-target organisms such as bees, potentially disrupting ecosystems.
