Although there are many types of dust mites, Dr. Stukus says they all do pretty much the same thing: hide in stuff, especially places that are warm and humid. That includes mattresses, pillows, and even your precious stuffed animals. The best thing to do is wash your bedding (teddy bears included) using hot water every few weeks. You might also invest in mattress and pillow covers that can help reduce the spread of the mites.
“Mold loves moisture,” Dr. Stukus says. Mold is most often the result of a water leakage, so it’s mostly going to be seen in places like your bathroom and kitchen. “But anywhere with poor ventilation is where mold can be found,” Dr. Stukus warns. So finding and fixing the source of that dampness is key, especially if the area isn’t well-ventilated.
