How To Test for Mold in Your House

Unexplained musty smells, sudden sneezing fits, persistent coughs or unexplained headaches might signal a mold problem in your home. While all homes naturally contain some mold, certain types can proliferate rapidly and potentially cause health issues. What makes mold particularly challenging is the variety millions of varieties exist, affecting different people differently.

Mold thrives through tiny spores that multiply in environments with moisture and organic materials. These microscopic spores can travel through your home via ventilation systems, wall cracks, and even electrical outlets. Though common molds appear in various colors, it’s worthwhile to note that color alone doesn’t indicate toxicity for instance, not all black mold is harmful.

Doing a DIY mold test may be the best place to start and help guide you to the next steps. Mold test kits come in a few forms, but these two are the most common:

• Swab Mold Test Kits test physical surfaces by collecting mold samples with a swab. Some kits include mold identification capabilities, helping you understand what type of mold you’re dealing with.
• Petri Dish Mold Test Kits offer two testing methods: capturing airborne spores in a room or collecting surface samples. These kits culture the samples to help identify mold presence and type.

Here, I test these types and allow you to choose which one works best for you. The main goal for any DIY mold test is to capture a sample without disturbing the mold and, in turn, making it airborne.

Safety considerations for dealing with mold

When handling any mold situation whether testing or removing proper safety precautions are essential:

• Always wear safety glasses, a respiratory mask, and disposable gloves.
• Avoid disturbing mold areas to prevent releasing airborne spores.
• Follow the test’s manufacturer instructions precisely.
• Consider professional mold remediation if mold is identified, especially in enclosed spaces like wall cavities or HVAC systems.

How To Use a Mold Swab Test Kit

• Use the swab included in the test kit to collect your sample by rubbing the cotton swab on the area of concern.
• Insert the swab back into the vial provided. Snap the other end and expose the liquid to the contaminated swab. Shake for 10 seconds.
• Lay test strips flat on work surface. Add 5 drops of the mold sample to both test strips. Allow to soak in for at least 5 minutes.
• Follow manufacturer’s instructions to read the results. Negative result will appear with a single line. Positive result will appear with two lines.
• If you wish further analysis of your mold sample, you may send it to the manufacturer for further information. Fees may apply.
