Houston floods have created massive colonies of floating fire ants

As tropical storm Harvey continues to pound the Texas coast, flood waters are rising in Houston, carrying with them debris from wrecked structures throughout the region. Locals are also reporting on Twitter that colonies of fire ants have been flooded from their nests, forming massive rafts drifting aimlessly in the water.

This phenomenon has happened before in other areas that are home to the devilish insects—although notably not during Hurricane Katrina because the floods came on too quickly and drowned the colonies instead.
