A Wormy Situation

This is about the gym in Sanctuary (somerset West) It's a great gym, but for the longest time now I have seen small black worms in the showers. It's weird because the cleaning staff are ALWAYS cleaning and hard at work. I gave it a google and the type of worm seems to be 'drain fly larvae' and I have seen a few of those suckers as well, so maybe the clock rooms need a good fumigation. Please sort it out!
