The attached photo shows a "floating raft" of thousands of fire ants after a flood the whole colony ready and able to recolonize it's self after the waters recede...this could be in abandoned homes, debris etc.
they will attack when disturbed ..en masse.
Then there's rattlesnakes, gators and lots of other displaced animal life swimming around..Bull Sharks in the rivers...sounds like a movie plot but it's happened before. So hats off to all those heroes in Texas
it's not just the elements their up against.
