What type of pest control product comes in various forms and features an attractive carrier for the target pest?

The correct answer is baits, as they are specifically designed to attract target pests while delivering a pest control agent. Baits often come in various forms such as granules, gels, or blocks, and are formulated to be appealing to the target pest in terms of taste or smell. This feature enhances their effectiveness because the pest is drawn to the bait, leading to more targeted control.

In contrast, insecticides primarily act as pesticides that kill or repel insects, but they do not necessarily have an attractive carrier specifically tailored for the pests. Repellents, on the other hand, are used to deter pests rather than attract them, making them unsuitable for the context of this question. Powders may also be used in pest control but do not typically have an attractive carrier component aimed at enticing pests. Therefore, baits stand out as the correct choice due to their design and purpose in pest control.
