You likely have never had any interest in studying a colony of ants (or any reason to even consider doing so). But if you ever did, you might occasionally find a colony with some unusual residents who don’t seem to belong with the rest.
Scientists have found that there are certain groups of ants that tend to raid other ant colonies, kidnapping some of their young members and using them as sort of indentured servants.
Of course, if you’re plagued by these pests, you likely don’t care about the makeup of their population or the origin of the colony’s members—you simply want to get rid of them.
There is an effective way to destroy the whole colony, and all of its assorted members. Ant bait is a popular weapon for battling and destroying large groups of ants. The worker ants who forage for food grab the bait and then take it back to the nest to share with the colony, where it wipes them all out.
