Do Spider Plants Get Rid Of Mould

Spider plants do not get rid of mould directly, but they can help improve indoor air quality, which may indirectly reduce mould issues.
 
If you’ve been wondering “do spider plants get rid of mould,” the honest answer is that these popular houseplants aren’t mould-eaters.
 
They can’t remove mould from walls, ceilings, or shower grout like a cleaning product would.
 
However, spider plants get rid of mould spores in the air to some degree by trapping them on their leaves and through their natural air-purifying ability.
 
In this post, we’ll explore whether spider plants get rid of mould, how they can help, and where they fall short.
 
Let’s break down everything you need to know about using spider plants to get rid of mould problems at home.
 

Do Spider Plants Get Rid of Mould? The Short Answer

Spider plants get rid of mould only in an indirect sense, not by directly killing or consuming the fungus itself.
 
Here’s what that means in practice:
 

1. Spider Plants Are Not Mould-Eaters

Mould is a fungus that grows on surfaces and feeds on organic matter like dust, wood, or drywall.
 
Spider plants get rid of mould spores by capturing them from the air, but they don’t digest or destroy the mould colony.
 
Think of them as passive air filters, not active mould removers.
 
So if you’re hoping spider plants get rid of mould completely, that expectation won’t match reality.
 

2. What Spider Plants Actually Do for Indoor Air

Spider plants get rid of mould spores by trapping them on their rough leaf surfaces.
 
These leaves also absorb certain volatile organic compounds (VOCs) like formaldehyde and benzene.
 
By reducing overall pollutants, spider plants get rid of some of the particles mould needs to thrive in the air.
 
This doesn’t mean they eliminate mould, but it helps create a cleaner environment that’s less hospitable to mould growth.
 

3. The Humidity Factor

Mould loves high humidity, but spider plants actually release moisture through transpiration.
 
So while spider plants get rid of mould spores, they also add a tiny bit of humidity to the room.
 
That sounds counterproductive, but in a well-ventilated space the effect is negligible.
 
The real benefit of spider plants and mould control is more about trapping spores than changing humidity levels.
 

How Spider Plants Can Help Reduce Mould Growth Indirectly

Even though spider plants get rid of mould only partially, they do support a healthier indoor environment.
 
Here’s how they contribute:
 

1. Trapping Airborne Mould Spores

Mould reproduces by releasing tiny spores into the air, and those spores circulate until they land on a surface.
 
Spider plants get rid of mould spores by catching them on their leaves, which can be wiped clean or washed.
 
Over time, this reduces the number of spores floating around your home.
 
If you regularly clean your spider plant’s leaves, it becomes a simple spore-trapping system.
 

2. Absorbing Pollutants That Feed Mould

Mould doesn’t eat pollutants directly, but dust and organic debris provide nutrients for mould colonies.
 
Spider plants get rid of some of these particles from the air, including dust and VOCs.
 
Less dust means fewer places for mould spores to settle and germinate.
 
While spider plants get rid of mould indirectly through this method, it’s still a helpful piece of the puzzle.
 

3. Encouraging Better Ventilation Habits

When you own spider plants, you naturally pay more attention to their environment.
 
You might open windows more often, improve air circulation, or check for mould more regularly.
 
Spider plants get rid of mould also by inspiring you to keep the room cleaner and drier.
 
That behavioural change can be just as important as the plant itself.
 

Limitations of Using Spider Plants for Mould Control

It’s important to be realistic about what spider plants can and can’t do.
 

1. They Can’t Remove Existing Mould

Spider plants get rid of mould spores, but they have no effect on mould that’s already growing on surfaces.
 
If you have visible mould on walls, floors, or bathroom tiles, you need to clean it with a proper mould remover.
 
A spider plant won’t stop that mould from spreading or eating away at your materials.
 
So while spider plants get rid of mould spores in the air, they’re not a replacement for cleaning.
 

2. They Won’t Stop a Mould Infestation

Serious mould problems usually come from leaks, high humidity, or poor ventilation.
 
Spider plants get rid of mould only as a supplementary measure, not as a solution to a major outbreak.
 
For large infestations, you need to fix the moisture source first.
 
Even a dozen spider plants won’t compare to a dehumidifier or proper ventilation.
 

3. Quantity Matters

One small spider plant in a large room won’t make a noticeable dent in mould spore levels.
 
To truly see spider plants get rid of mould spores effectively, you’d need several plants spread throughout the space.
 
Studies on air-purifying plants suggest that multiple plants are required for measurable results.
 
So don’t expect a single spider plant to solve your mould worries.
 

So, Do Spider Plants Get Rid of Mould?

Spider plants do not get rid of mould directly, but they can help reduce airborne mould spores and improve overall indoor air quality.
 
They trap spores on their leaves and absorb certain pollutants that contribute to a mould-friendly environment.
 
However, spider plants get rid of mould only to a limited degree and should never be your primary defence against existing mould growth.
 
If you’re dealing with mould, clean the affected area, fix moisture issues, and use a dehumidifier.
 
Then add spider plants as a natural, low-maintenance helper to keep your air fresher.
 
Hope this post has cleared up the question “do spider plants get rid of mould” and given you a realistic picture of their benefits.
