Why are baits popular for ant control?

• A. They kill on contact
• B. The ants will take it back to the nest for distribution
• C. They repel ants
• D. They poison the entire area instantly

Answer: (D)

Baits are popular because they use the ants’ own foraging and social feeding to spread poison through the colony. When a foraging ant takes the bait back to the nest, it shares it with nestmates, and the slow-acting poison has time to move through the colony. This allows the entire colony—including the queen—to be affected, not just the ants that happen to touch the bait.

Killing on contact only reduces the number of ants that touch the product, without necessarily impacting the colony as a whole. Repellents don’t kill or distribute poison, so they don’t solve the problem of a growing colony. And poisoning the entire area instantly isn’t how bait systems work—the effect builds over time as the bait is distributed among workers and transferred within the nest.

So the best description is that ants will take it back to the nest for distribution.
