Subterranean termite baits such as Sentricon (noviflumuron) and hexaflumuron products use a chitin synthesis inhibitor (CSI) as the active ingredient. By what mechanism does this active ingredient actually kill a worker termite that has fed on the bait?
- It paralyzes the termite's nervous system within minutes of ingestion, like a fast-acting contact insecticide
- It acts as a stomach poison that ruptures the gut lining immediately after the bait is eaten
- It disrupts the molting process, so the worker dies when it next attempts to molt (typically weeks later)
- It sterilizes the queen directly so that no new workers are produced
- It repels the termites from the treated wood so they starve away from the structure
