Moisture can show up fast in bathrooms, kitchens, and basements—and those are some of the most common places mold and bacteria love to grow. Even if you clean every day, mold can still sneak in when there’s leftover dampness.

Hidden dangers

Mold isn’t always obvious. It can hide behind walls, inside books, on baby toys, and in other places you might not think to check—especially spots that stay dark and damp.

Black mold

Black mold can release mycotoxins that may lead to breathing problems, headaches, and other serious health issues for both people and pets if it’s breathed in.

Green mold

Not all green mold is dangerous. Sometimes it’s Aspergillus or Penicillium, which may not bother someone with a healthy immune system—but it can be a bigger issue for anyone with asthma, allergies, or a weakened immune system.

Pink “mold”

Pink buildup (often called Serratia) usually shows up in showers and other areas where soap residue collects. It can irritate breathing and is best cleaned up as soon as you notice it.

How to kill mold safely

A simple at-home option is white vinegar on hard surfaces (like tile, sinks, and shower walls). Spray it on, let it sit for a bit, then scrub and rinse well.
