BAD SMELL IN YOUR CRAWL SPACE

CRAWLSPACES AND HUMIDITY Typically, basements and crawl spaces are below the ground level of the house, which causes them to accumulate moisture. The combination of humidity and lack of sunlight can lead to odors caused by the growth of mold and other organisms. However, you may find other worrying problems such as leaking pipes.
Likewise, most homeowners visit their crawl space only when they need to do inner works, such as checking the heating or cooling system and plumbing. When basement and crawl spaces are unkempt, weather changes create seasonal variations in moisture and condensation in the lower parts of your house. If crawl spaces are not properly sealed, dampness and the absence of sunlight may lead to mold issues and rotten organic materials, as well as pests like insects and rodents.
MOLD
Indeed, the mold itself may not cause odors, but decayed materials as a result of mold forming release smell. Also, mold spores are micro toxins that can be dangerous to human health.
PESTS AND WILDLIFE Many homeowners believe that vented crawl spaces are the best solution to fix unpleasant odors. However, unsealed crawl spaces have small gaps through which insects and rodents can enter. Pests pollute the area, and this problem can be the source of many unpleasant smells. Mice grow and reproduce rapidly, and maybe you will need to call a pest control company.
VENTED CRAWLSPACES Vented crawlspaces are a common myth among homeowners and builders. And vents allow humidity to enter their homes. Outside air may lead to uncontrolled moisture that causes mold, mildew, and pests. As we said before, mold spores travel through the living area and harm the indoor air quality. Vented crawl spaces are not the best solution to prevent building materials from being damaged by moisture.
On the other hand, unsealed crawl spaces are open doors for odors originating from the soil that naturally contain moisture and a variety of organic materials. Even if your foundations are made from concrete, dampness beneath the slab will eventually find its way into the crawl space.
