Being a former resident of Oklahoma for several years, I feel pretty qualified in saying that summers there can be... well, the exact opposite of comfortable. Temperatures and humidity levels reach triple-digits (and yes, I know 137% humidity is not scientifically possible, but it sure felt like it sometimes), and weird bugs start showing up that have no damn business on planet Earth. But in all my years there, I'd never seen red worms oozing out of my bathtub drain like something out of the 1976 movie Squirm. Here's a handy visual aid in the form of that film's trailer, which features – you guessed it – a bathroom just overflowing with bloodsucking worms:
This summer, in the town of Colcord, OK, these red wrigglers bypassed the city's filtration systems and started showing up in people's tap water, and late last month the city authorities actually had to close schools and warn residents not to wash, drink, cook with or brush their teeth with the worm-infested H20.
Bloodworms are the larva of a non-biting species of mosquito, and don't suck blood themselves; they're actually named for their blood-red color. Still, since the species is commonly found in polluted waters, they can potentially carry dangerous diseases... and they're in the drinking water, for crying out loud. Plus, they're damn near impossible to kill; they can even survive in pure bleach for extended periods of time.
The cause of the infestation has not been determined as of this writing, and this is not even the first time this has happened: the same worm invasion occurred 20 years ago in the nearby town of Drumwright.
