Better be careful so you don't end up with a dead anteater/aardvark in your backyard.

According to the Austin paper around 2-3 years ago, a local stream had a massive fish die-off that was first thought to have been caused by chemicals or pollution. After scientific study it turned out that the fished died of poisoning. It seemed that the fish were pigging out on winged fire ants that had landed on the stream's surface. After filling their stomachs, they died as the fire ants defended themselves by biting and injecting their poison into the fish's stomachs.
