Are ants found inside a structure always from a colony located inside?

The assertion that ants found inside a structure are always from a colony located inside is incorrect. Ants are known to enter buildings from external colonies in search of food, water, and shelter, especially during certain times of the year when conditions outside become unfavorable.

For instance, many ant species can travel significant distances from their nests to find resources. It's common to find ants inside a home that originate from outdoor colonies, particularly when they are foraging. Additionally, some ant species may establish colonies within structures, but this isn't the case for all ant encounters indoors. Weather and environmental conditions also play a role in the behavior of ants, influencing their movement and nesting habits.

Understanding this concept is crucial for effective pest management and control, as it informs strategies for eliminating both the ants already inside and preventing further incursions from external colonies.
