Which of the following is NOT a non-repellent termiticide?

The selection of Demon TC as the answer is based on its classification among termiticides. Demon TC, which contains the active ingredient cypermethrin, is a repellent insecticide. This means it creates a barrier that termites can detect and avoid, preventing them from coming into contact with treated areas.

On the other hand, the other options—Termidor, Altriset, and Sentricon—all represent non-repellent termiticides. Non-repellent termiticides work differently; they do not create a barrier that termites can sense. Instead, these products can be absorbed by termites as they move through treated areas, allowing for the transfer of the active ingredient within a colony, leading to more effective control of termite populations. This feature makes them particularly valuable in managing termite infestations.

Understanding these distinctions is crucial for professionals in pest control, as selecting the appropriate type of termiticide can significantly influence the effectiveness of treatment strategies against termites.
