10 Ways to Get Rid of Gnats in Houseplants Fast

10. A Light Soap Solution: The Quick Surface Spray

A clear plastic spray bottle filled with a light soap solution sits on a rustic wooden table outdoors, next to a lush green fern frond. This homemade 'quick surface spray' is a gentle option sometimes used to help manage adult gnats in house plants or to clean plant leaves.

Sometimes, you just want to zap those fungus gnats on the spot, right? For those moments, a simple, light soap solution can be your best friend. It’s a quick and easy way to reduce the flying population directly. This is all about immediate pest reduction.

Zap ‘Em on the Spot! The Instant Gratification Spray

When you see an adult gnat buzzing around your favorite fern or landing on a leaf, a quick spritz with a mild soap spray can often stop it in its tracks.

This method is great for those times when you just want to deal with the ones you see right then and there.

How a Little Soap Can Stop a Gnat in its Tracks

So, why does this work? A diluted solution of gentle liquid soap, when sprayed directly onto an adult gnat, can disrupt its outer protective layer.

This essentially leads to dehydration and kills the gnat. It’s a quick knockdown for those annoying flying insects.

My “Oh, That’s All It Takes?” Soap Spray Moment

I remember one afternoon, feeling particularly bugged by gnats doing aerial acrobatics around my prized orchid. It’s a beautiful Phalaenopsis that I’ve babied for ages here in my San José del Cabo place.

I didn’t have any commercial insecticidal soap handy at that moment. But I recalled reading that a very mild soap solution could work.

I mixed up a tiny batch with a bit of Dr. Bronner’s unscented castile soap I had (a staple in my house!). I did a quick test spray on a paper towel, then aimed for a gnat. Success! It actually worked to knock it down. It was such a simple, yet effective, bit of DIY pest control.

Mixing Your Super-Simple Gnat Zapper

Making this spray couldn’t be easier. You’ll need a clean spray bottle, some water, and a very gentle liquid soap.

The key here is to use a MILD soap. Think castile soap or a basic liquid soap that doesn’t have a ton of detergents, fragrances, or degreasers in it. Harsh detergents can actually harm your plant foliage.¹

Add just a few drops – maybe a quarter to half a teaspoon of soap per pint of water – to your spray bottle. Give it a gentle swirl to mix; you don’t want a bottle full of suds.

Spraying Smart: Tips for Using Your Soap Solution

When you spot those adult gnats on your plants or zipping nearby, give them a light, direct spritz. Direct contact with the gnat is usually needed for the soap to do its job.

Now, this is really important: always test your soap spray on a small, hidden leaf area of your plant first. Wait about 24 to 48 hours and check for any signs of leaf burn or discoloration.

Some houseplants are more sensitive to soaps than others.² Also, it’s best to avoid spraying your plants when they’re in direct, hot sunlight, as this can increase the risk of leaf damage. This is key for good plant foliage care.

A Quick Fix, Not a Cure-All

This light soap solution is excellent for quickly reducing the number of flying adult gnats you see. It gives you that instant gratification of getting rid of a few pests on sight.

However, it’s important to remember that this method primarily targets the adult, flying gnats. It doesn’t do much, if anything, for the gnat larvae developing in the potting soil.

So, for long-term gnat control, this soap spray is best used as a supplementary tool, in combination with other methods that address the entire gnat life cycle.
