You found some spots inside your household and you’re worried what it might be. You look up online for possible solutions and remedies to take care of this problem, but the problem is, you are not exactly sure what it is. It is easy to mix up mold with mildew as they are both fungi that are known for thriving in warm areas with lots of moisture. Here are some tips on how to tell the difference between the two!


One of the easiest ways to differentiate the two is by their appearance. Mold tends to be green or black and it usually grows underneath the surface of anything that has gotten wet. The texture of molds can be fuzzy or slimy. On the other hand, mildew is usually white, gray, or sometimes yellow and grows on the surface of moist, warm areas.


Both of these fungi thrive in warm, moist places. Although, each type seems to have a fondness on the area it wants to start growing. Most often than not, mildew can be found on items that have damp surfaces such as fabric, paper, or leather materials. They can also be found on floors, walls, or ceilings where humidity can be pretty high such as bathrooms, kitchens, or basements. Mildew can also be found in some food such as potatoes or grapes, but molds are more often the type of fungi found on food. Food such as cheese, bread, or meat are prime locations mold can be found in. In addition to food, molds can also be found in indoor or outdoor areas that may have gotten wet such as crawl spaces and garages.


Mildews may be harmful to the food it grows on, but it doesn’t typically damage other surfaces such as the bathroom floors or mirrors. Although this may be the case, mildews should still be removed as quickly as possible as it poses minor health risks such as coughing, headaches, or people exposed may have trouble breathing.

Molds do not only cause major damages to entire structures but also pose serious health risks. Mold damages homes and vehicles and can cause long-term health problems to people exposed to it. There is a huge gap when it comes to the difference between the two types of fungi as molds pose higher risks to people. Health problems may include respiratory issues, heart problems, migraines, fatigue, joint pain, and depression. In addition to these, people with mold allergies experience congestion, sneezing, and irritation of the eyes, throat, and skin.
