High Humidity in Home Encourages Dust Mites and Mold

You know how it feels outdoors–high humidity can make hot days unbearable, sticky, and drive you into air conditioned places. In Southern California, we are more likely to brag about our “dry heat,” but up north cool, foggy weather is very common. Both hot and cold damp days make it easier for mold and dust mites to thrive indoors, leading to allergy symptoms and even asthma for those with sensitivities.

How does high humidity encourage dust mites and mold?

This video from the IAQ Video Network lays it out very well:

Mold spores are everywhere, just waiting for the right conditions to grow and thrive.

What does mold need to grow?

Mold only needs three elements to take hold:

  • Moisture
  • Food
  • Air

That’s it! No wonder a leak or some unfortunate condensation can cause a mold problem indoors.

What about dust mites?

Dust mites are also ubiquitous and live on dead skin cells and pet dander–unavoidable in an inhabited residence. Dust mites don’t drink, but they do need water and do well in a humid environment.

What can you do to discourage dust mites and mold?

  • Fix leaks promptly
  • Replace any porous materials damaged by water
  • Run bathroom fans during and after showers until steam and humidity has been vented outdoors
  • Use a dehumidifier to keep indoor humidity low
  • Wash bedding in hot water and dry in a hot dryer weekly

We can’t do much about the outside humidity–it depends on the climate where we live. But high humidity indoors is more controllable and worth the effort, especially if you or someone in your family is affected by allergies or asthma. If you develop a mold problem or want to tackle dust mites, Seacliff can help. Call us for a consultation!


Crawl space Moisture and Mold

A crawl space in a home can be an inviting place for moisture and mold to exist. Crawl spaces maintain conditions that allow for mold to grow and can cause other problems. When moisture levels are high and water is present, you will begin to see a colony of mold.

 Requirements for Mold to Grow in a Crawlspace

1. Water: Plumbing leaks or a drainage problem can cause standing water to exist and cause mold to grow and major foundation problems. Fix them immediately!

2. Moisture: Moisture that evaporates can ruin pressed wood and invigorate mold to grow.

3. Outdoor Air: When air from outdoors enters a crawl space and cools down and humidity levels are high,temperatures inside can escalate.

Symptoms of a crawl space moisture problem can cause mold to grow, musty odors to exist, and increase humidity levels. If you suspect to have mold in the crawl space of your home, it’s important to remediate the mold.
