How do termite baiting systems operate to reduce a termite colony?

• A. They instantly kill the entire colony upon contact
• B. They attract predators that feed on termites
• C. They repulse termites without killing them
• D. They deliver slow-acting toxins through foraging termites, which spreads to others and can lead to colony decline

Answer: (D)

Termite baiting systems rely on social feeding to suppress the colony. The bait is attractive to foraging termites, who carry the slow-acting toxin back to the nest and share it with other members. Because the toxin works gradually, termites continue to forage and spread the poison through trophallaxis and grooming, which gradually reduces the worker and breeding potential and leads to colony decline over time. This approach targets the whole colony rather than instantly killing individuals, unlike sprays or contact methods. The result is a prolonged, controlled suppression as the nest becomes unable to sustain itself.
