What may happen when trying to control pharaoh ants by spraying workers with liquid insecticide.

• A. The colony may fragment, increasing and making control more difficult
• B. Ok, isn't that what were supposed to do? Duh!
• C. Only do that using phantom
• D. None of the above

Answer: (A)

When you spray liquid insecticide on pharaoh ants, you can cause the colony to fragment into multiple nests. Pharaoh ants live in many interconnected nests with several queens, so killing or driving workers in one area often prompts survivors to relocate and establish new nests. This fragmentation leaves parts of the colony intact and harder to reach, so overall control becomes more difficult rather than easier. In practice, spraying workers is typically avoided in favor of non-repellent baits that workers take back to the nest, delivering poison to the entire colony, including the queens. The other options aren’t consistent with how pharaoh ants social structure and responses to spraying work.
