Check Your Petri Dish
After 48 hours, check your petri dish for signs of mold growth. If you do not see mold, wait another 24 hours and check again. If you still dont see mold, wait again for 24 hours and check one last time. If you do not see mold growth after 96 hours, your test did not detect any mold. If you do see mold on your test plate, you should take additional steps to remove the mold.
How To Test For Mold
You probably don’t need to do mold testing or buy a mold test kit, especially if the fungus is visible. Because the health effects of mold vary from person to person, the CDC says that if you can see it or smell it, it should be removed, no matter what type of mold is in your home.
While it’s not possible to completely eliminate mold in your house, you can prevent a build-up by cleaning up any wet or damp spots and fixing any existing water leaks.
Neither the CDC nor the Environmental Protection Agency recommends doing routine mold samplingsboth organizations point out that there are no federal limits for mold in buildings, so people can’t check their apartment complex’s compliance with the law, for example. Plus, the testing can be expensive.
You Find Dark Or Colored Spots On Your Walls
Mold can appear in many shapes, textures, and colors. It can look like anything from green, dripping slime definitely something youd notice to an innocuous-looking grey fuzz. If your walls are coming out in spots, its worth double-checking that there isnt a leak in the pipes or uncontrolled humidity in the room.
If you have a pre-existing breathing problem that seems to flare up after long periods at home, mold could be the culprit.
Most species of household mold wont bother people without breathing issues but can aggravate asthma in individuals who already suffer from the condition. Consider scheduling a doctors appointment and a mold inspection if your breathing problems seem to worsen without a clear cause.

You Notice A Bit Of A Musty Or Damp Smell
If you notice that your home has a bit of a moldy or musty smell to it, that might also indicate that there may be a mold issue.
“Many different mold species have different odors, so it is difficult to pinpoint the exact smell, however, if it is an odor that isn’t common in your home or building, then it should be investigated,” George Hernandez, the vice president of operations at PuroClean, told INSIDER.
Physical Or Medical Symptoms
Unfortunately, mold can cause a variety of health problems. Mold can cause infections, allergic reactions, and toxic effects in some individuals, but the clinical effects can vary from person to person, says Kelly Johnson-Arbor, M.D., medical toxicologist and co-medical director at the National Capital Poison Center in Washington, D.C.
For people with intact immune systems, mold can causeor worsenallergic reactions and asthmatic symptoms, such as shortness of breath, wheezing, and coughing, she tells us. Fungal infections, which can involve the blood, brain, lungs, or other organs, are more common in people with weakened immune systems.
As mentioned above, molds can also produce toxins called mycotoxins. “Some mycotoxinslike aflatoxins and ochratoxinscan cause significant human disease, but the clinical effects of other mycotoxins are less well understood, Johnson-Arbor says.
It’s also worth noting that the fungus Stachybotrus chartarum was once thought to cause serious medical conditions including pulmonary hemorrhage, though there is currently a lack of evidence linking it to serious medical conditions in most people.

Signs Of Mold In Your House
There are several subtle signs that indicate that your home may have harmful mold.
1. Strange smell from the air conditioner or heater
If you think your heater or air conditioner has an unusual smell, you might want to check it out.
A stand-alone air conditioner is one of the main places where mold starts to grow. These devices are dark, damp, and often exposed to warm temperatures when not in use. If you put your air conditioner in a warm place in winter, this also increases the risk of mold.
Regularly check the condition of the air conditioner and clean it every two years.
2. The seams between the bathroom tiles have become dark
When you take a shower, pay attention to the seams between the tiles. If they are dark, it is most likely mold. Luckily, this type of mold is not that dangerous.
However, if your bathroom has been leaking recently or flooding an adjoining room, you may be dealing with a more toxic type of fungus that will be harder to remove.
3. Wallpaper starts peeling off
While wallpaper may discolor or wear out over time, wallpaper peeling is not normal. If the wallpaper bubbles or cracks, this indicates the presence of moisture on the walls. And moisture is a precursor to mold.
Pay attention to walls and any areas that look damp or warped.
4. Your cold wont go away
Symptoms of a mold reaction may be subtle. It can be a common runny nose or bouts of sneezing. If you feel like your cold has dragged on, this could be a hidden sign of a mold problem.

Moisture: Investigating And Solving Problems
Mould will grow indoors if moisture is present. Moisture problems in homes may result from:
- daily activities such as showering or bathing, washing clothes or cooking, if exhaust fans are not working properly or are not used
- infiltration of water from the outside when there are cracks or leaks in the foundation, floor, walls or roof
- plumbing leaks
- moisture condensation on cold surfaces
- flooding due to weather conditions
- inadequate ventilation.
Moisture indoors accumulates when it cannot be vented outside and becomes a problem when building materials become damp or wet.
Moisture problems are preventable.
Unless the cause of the moisture problem has been identified and solved, mould will reappear. Once the moisture problem and its causes have been identified, they must be fixed. To prevent future problems, measures should be put in place to control sources of moisture in your home, for example:
- Ensure rain, irrigation water and snowmelt drain away from the house by sloping the grade away from the building.
- Keep eavestroughs and downspouts clean of debris and ensure that the outflow runs away from the house and not into neighbouring foundations.
- Repair plumbing leaks promptly.
- Use exhaust fans, ventilation and air conditioning systems to vent moisture outdoors.
- Use moisture tolerant materials in areas likely to get wet .
Run a dehumidifier in damp areas such as basements or if you observe that moisture is condensing on cold surfaces such as window panes.
Your Planter Of Begonias Is Leaking
Exterior landscaping that is close to the home, as well as planters placed against exterior walls, can also lead to mold issues, especially for stucco homes, says Gregg Cantor, President and CEO of Murray Lampert Design, Build, Remodel. Moisture finds its way inside the walls and can cause mold growth in the drywall and insulation. This type of mold growth can be particularly dangerous because its rarely caught until the mold shows up on the interior of the wall, at which point the growth can be extensive and a danger to your health, says Cantor. Watch out for these other sneaky backyard dangers you need to be aware of.

You Feel Like You Have A Lingering Cold Or Are Battling Flu
“It is pretty tough to detect until it starts coming through the walls because mold, as you know, is a problem with some sort of leak somewhere,” Hayes-Raitt said. “So the problem starts behind the walls. But if you’re getting sick, it might be because of a mold problem.”
If you’re dealing with symptoms that you can’t exactly pinpoint, it could be that you’re stressed, haven’t been taking care of yourself, or wound up with some sort of virus, of course, but it could also potentially be that you’re dealing with mold.
If possible, Hayes-Raitt said that one of the best ways to determine if the sickness you feel is related to the house or not is to leave for a few days and then return home. If you feel those same symptoms coming on again, it might be the result of something more than a cold or virus.
