Which of the following is NOT a formulation used in ant control?

Gels are indeed used in pest control, including ant control, primarily because they can be effective in delivering active ingredients in locations where ants are foraging or nesting. They provide a good option for targeted application since they can stay in place and attract ants, allowing them to ingest the poison.

In contrast, wettable powders, granules, and baits are all common formulations specifically designed for ant control. Wettable powders can be mixed with water for application, granules can be spread in areas where ants are active, and baits are formulated to attract ants and allow them to carry the insecticide back to their colony.

While gels are an effective method of targeting ants, they are not one of the primary formulations typically highlighted when discussing common ant control methods. Hence, the focus on the lesser-known use of gels in comparison to the well-established methods of using wettable powders, granules, and baits makes this distinction clear in the context of ant control solutions.
