Which of the following termiticide classes does not target the nervous system?

Borates are a class of termiticides that do not target the nervous system, which differentiates them from other termiticide classes. Instead of disrupting nerve function, borates work through a different mechanism. They act primarily as a stomach poison by affecting the metabolism of the insect when ingested. This means that when termites consume borate-treated materials, it interferes with their ability to utilize essential nutrients, ultimately leading to their demise.

The other classes mentioned—chlorinated hydrocarbons, organophosphates, and pyrethroids—primarily function by interacting with the nervous systems of insects. Chlorinated hydrocarbons disrupt nerve function by blocking neurotransmitters, organophosphates inhibit enzymes that are critical for nervous system function, and pyrethroids affect ion channels in nerve cells to cause paralysis.

Understanding how different termiticide classes operate is crucial for effective termite management and selecting the appropriate treatment strategy.
