Final answer:
Applying persistent, fast-acting, contact insecticides indoors does not affect the success of baiting for ants, because baiting works by attracting ants to consume the bait and eliminate the entire colony.
Step-by-step explanation:
Applying persistent, fast-acting, contact insecticides indoors does not affect the success of baiting for ants. This is because baiting works by attracting the ants to consume the bait and carry it back to the colony, effectively killing the entire colony. Contact insecticides, on the other hand, kill ants on direct contact but do not eliminate the entire colony. Therefore, using contact insecticides alongside ant bait can hinder the baiting process and reduce its overall effectiveness.
