If you have a problem with pests in your home, whether they are mice, termites, cockroaches, ants, or earwigs, and have tried to eliminate the problem to no avail by setting baits and traps, it may be time to look in your crawl space to see if there's a moisture problem. Crawl spaces are notorious for excessive moisture and humidity that can cause problems throughout the home, including with pests since they need water and moisture for survival. Fortunately, there are a few things that can be done to eliminate the moisture and humidity and thus prevent condensation on your windows. Here's what they are.
Eliminate Seepage of Groundwater
The moisture and humidity in your crawl space are likely coming from the seepage of groundwater around the foundation. You'll need to eliminate this seepage by installing a vapor barrier and insulation. Another thing that helps is to make sure your downspouts are directed away from the foundation. If you live in an area that receives an abundant amount of rain or snow, consider installing a drainage system around the perimeter of your home as well, such as a French drain, which utilizes a perforated pipe and gravel to prevent groundwater from reaching your foundation.
Seal the Crawl Space Vents
With groundwater being unable to seep into your crawl space, you should then seal off the vents to your crawl space. Vents tend to allow moisture inside the home. It's important to wait to seal the vents until after the seepage has been eliminated because, otherwise, you would only be trapping the moisture and humidity inside the crawl space. You may be wondering why the vents were installed in the first place if they helped create the problem. The answer is that research now shows that venting a crawl space does not help keep the home dry as previously believed.
Install a Dehumidifier & a Hygrometer
After the water seepage has been eliminated and the vents sealed, install a dehumidifier in the crawl space or inside your home to control the moisture and humidity that may continue to naturally occur, although greatly reduced. It's also a good idea to have a hygrometer in your crawl space or in the living area of your home, such as beside the thermostat for your heating system. A hygrometer is a device that measures humidity levels. Your crawl space encapsulation contractor will be able to help you determine which make and model of these devices you should use in your home.
