Any big box home improvement or hardware store sells home mold test kits, and they are inexpensive. The standard mold test contains a petri dish and a substance that creates mold growth. You place this dish with the substance in your home and after a stated time, put a lid on the dish, and incubates. Every manufacturer will have their own guidelines and follow their instructions exactly to get the best reading. If the dish contents mold grows, then your home has mold.

Another colorless, odorless, and tasteless killer undetectable without a detection device. Radon won’t asphyxiate you but has long-term danger like lung cancer.
