15 years ago it seemed like a prank call when someone told us they had a problem with ‘grout worms’ in their shower, but now our service manager has taken a picture of what was likely lurking in the crevices of that shower and several others we’ve seen lately — tiny larvae that grow into little flies and thrive in the damp recesses of a well-used shower.
When life gets away from us and routine cleaning with a PH Neutral cleaner isn’t done regularly, a shower can be a great breeding ground for mold and mildew. [It takes 3 things for mildew to thrive — a food source (soap scum and skin cells), water, and absence of light.] Many showers are poorly ventilated (or the fan is not used properly), and long showers and sporadic cleaning make them the perfect breeding ground for mildew and the tiny mites our caller was referring to as “grout worms.”
On the opposite extreme, we have also seen these larvae in over-cleaned grout lines. Each time bleach or some other overly harsh product is used, the pores of the grout open more, and mold and mildew are given an even better nesting place. This is why some people tell us that the more they clean, the more quickly mildew & other scum seems to develop. It’s because they are cleaning with a product that is too harsh for the grout, and they are actually eroding the cement in the grout.
Tile and grout are meant to last a long time, but, like all things, they have to be properly maintained. When you clean, do yourself, the environment, and your grout a favor and use a pH Neutral cleaner. It will make your grout last longer, do a better job of keeping away any “grout worms” and help your tile installation remain one of the trouble-free parts of your home. (Assuming it’s installed correctly in the first place, of course.)
Here’s to good installations and no more calls about “grout worms” 🙂
