Do you have crawl space or basement? If you have crawl space, then you should encapsulate it.
- Increase airflow in your basement or crawl space. Add a pest proof window that you can open and close. Or operate a fan based on humidity or temp, similar to a gable/attic fan.
- Add a properly sized dehumidifier that pump water out of your house to keep the humidity low.
- Keep plants away from your house if your house is swamped by plants. Plants hold ton of moisture and it's great for your air, but terrible at humidity.
