When I first started learning about mold and moisture is crawlspaces, I was shocked to discover that mold and moisture are the reason I have so many critters in my crawlspace! Crickets, spiders, and other creepy crawlies come into crawlspaces to find water and food and a snug home for the cooler months. A nice damp crawlspace is their ideal home, so the damper and more musty the crawlspace, the more critters you find inside them! Eww!
Thankfully, it is possible to dry out crawlspaces and seal them off from outside air. This way, you can decrease critters, improve indoor air quality, and improve your heating and air conditioning costs!
