A lot of people will tell you not to mess with Argentine ants, because they assume, like all insects, AAs keep our delicate ecosystem in check in a variety of world-saving ways. But I won't say that, because I have a library card and my mother didn't drink while she was pregnant with me. While most insects are important to our ecosystem, Argentine ants are far from it. They're just awful bastards and they're worse than mosquitoes. As annoying and malaria-filled as mosquitoes are, we can't get rid of them all, because they provide food for fish, and they also eat up lots of nasty algae and bacteria. They belong in a circle-of-life kind of way, the way that everything belongs.
Except, that is, Argentine ants. As you probably guessed by their name, these buggers are from (and were supposed to stay in) Argentina. Despite that, they're all up in California's shit, as well as the shit of every other continent except Antarctica. They are, first and foremost, invaders, ranked among the 100 worst animal invaders of all time. They're not playing some important positive role in our ecosystem because they don't even belong here, they're just creating a blind trail of destruction and domination.
"Hi, I was exploring your thoughts earlier and I noticed that you're planning on destroying me. I wish you wouldn't think like that."
They used to be part of a functioning ecosystem back in Argentina. According to Elissa Suhr, a doctor in the field of FuckAntsForeverology, "In Argentina ... ant colonies span 10s of meters, are genetically diverse and highly aggressive towards one another, so population numbers never explode and they are no threat to other plants and animals." In Argentina, they were kept in check, like good little shithead bastards, but as soon as they travel out to Australia or California or England or any other damn place, their natural predators are gone and their population blows up. The ants realized that they weren't kings of their domain, so they decided to go find someplace where they could be, like a jaguar that trains itself to fly when it realizes it can't compete with lions for land dominance.
