What is the purpose of an Attractant in pest control?

An attractant in pest control serves to lure pests to a trap or bait, ultimately reducing their population. Option A, repelling arthropods, would not be effective in controlling the pest population as it would simply drive them away. Option B, counteracting anticoagulants, is not related to the purpose of an attractant. Option D, sanitizing equipment, is also not relevant to attracting pests. Therefore, option C is the most appropriate answer for the purpose of an attractant in pest control.
