What type of termites are commonly treated using baiting systems?

Baiting systems are primarily effective for managing subterranean termites because these termites live in colonies underground and create tunneling systems to access wood above ground. The bait stations are placed in the soil and can effectively lure the subterranean termites, which then consume the bait and bring it back to the colony, effectively targeting the broader population.

Formosan termites, although a type of subterranean termite, are often considered a specific subtype and can also be treated using baiting systems, reinforcing that they fall under the same treatment methods suitable for subterranean species. Drywood termites, on the other hand, do not rely on soil and have a different behavior and nesting habits, making them less susceptible to baiting treatments.

Thus, the choice recognizing subterranean termites as primarily treated with baiting systems accurately reflects the method's strengths and the behavior of these termite types, confirming the effectiveness of such systems in controlling their populations.
