Spinosyns are a class of insecticides derived from a naturally occurring fermentation product of the bacterium Saccharopolyspora spinosa. They target the nervous system of insects by binding to specific sites on the nicotinic acetylcholine receptors, leading to continuous stimulation of the nervous system, which ultimately results in paralysis and death of the insect. This mode of action makes spinosyns particularly effective against termites and other pests that pose a threat to structures.

Chitin inhibitors, insect growth regulators, and borates do not primarily target the nervous system. Chitin inhibitors disrupt the formation of chitin, leading to failure in molting. Insect growth regulators mimic hormones that control growth and development, preventing insects from reaching maturity or reproducing. Borates work primarily by disrupting metabolic processes and are effective as a preventative measure and treatment against wood-destroying organisms but do not interfere directly with the nervous system.

Understanding these differences clarifies the specific role that spinosyns play in pest control and highlights their effectiveness as a targeted treatment for termite infestations.
