Thrips are tiny insects that dehydrate plants by sucking moisture from their leaves, which results in browning, discoloration, and dehydration. They appear as clusters of tiny white grubs on the leaves or stems as larvae. Adults resemble lean brown flies.
Thrips can be eliminated in a few different ways. If there are only a few of the damaged leaves, you can entirely prune them to solve the issue. Another well-known natural insecticide is neem oil; it appears frequently on this list. Simply buy some neem oil in its purest form or a neem oil spray and adhere to the instructions on the bottle. Spray to eliminate adults and eggs every few days.
Diatomaceous earth can also be applied to the leaves as an alternative. This particular sort of powdered sedimentary rock has tiny, razor-sharp edges that, when consumed by insects, kill them, while remaining harmless to your plant. (However, purchasing a food grade variety wouldn’t hurt to be extra safe.)
Mealybugs
Scales without a shell are known as mealybugs; we’ll talk more about them later. They remove the juices from the leaves, causing spots and discolouration and leaving behind honeydew, a sticky, transparent goo. Even if you don’t see any actual mealybugs, this honeydew and cottony material on the leaves are indicators of an infection (the females produce this when they lay eggs).
Start by rubbing alcohol-dipping a cotton swab and dabbing any bugs or cotton you notice to get rid of mealybugs. This instantly kills the bugs. Mealybugs prefer to conceal themselves, therefore you should also thoroughly treat your plant with neem oil.
Gnats
Although adult gnats are more bothersome than damaging, the soil-dwelling larvae may munch on your plant.
The simplest technique to get rid of gnats is to remove the top few inches of soil to release the larvae and then put fresh dirt on top. Gnats lay their eggs in the soil. Another nice choice is to repotted your plant if it can handle it. Bacillus thuringiensis, a non-harmful microbe, can also be sprinkled over the soil’s surface.
Spider Mites
Spider mites are a fairly prevalent bug that can nibble on the leaves of your plant and suck out the sap, which results in discolouration.
Spider mites might appear as clusters of tiny brown dots and prefer to reside on the undersides of leaves. Until you realize the dots are moving, it’s simple to mistake these for leaf spotting!
Fortunately, spider mites are rather simple to remove with a water jet. Squirt the grouped bugs off using a kitchen syringe filled with water, give the plant a lukewarm water shower, or hose it off if the weather is warm.
To shield your plant from bacteria, fungus, and insects, we advise using Houseplant Leaf Armor. It performs the same functions as neem oil without the disagreeable smell. Additionally, the Houseplant Leaf Armor cleans and polishes the leaves of your houseplant.
Scale
The scale insects resemble tiny brown lumps. What you’re seeing is actually just the insect’s outer shell; underneath, the genuine bug lurks, sucking juices from the leaf and killing the plant as it does so. If they are left unchecked, they could kill your monstera.
Picking them off is a good way to get rid of them. Use your fingers, a toothpick, a butterknife, or anything else you choose. Make sure not to cut your plant, though! Neem oil, Houseplant Leaf Armor, or a mild insecticidal detergent like Safer Soap can be sprayed on the plant after you’ve taken what you can out.
Your monstera doesn’t have to end in disaster because of insects! Keep an eye out, take precautions to avoid infestations, and exterminate insects from your monstera as soon as you find an issue. The happiest monstera on the block will belong to you!

Why are there gnats on my Monstera?
Because they neither attack nor reside on the plant itself, fungus gnats stand out from the rest of the list. As the name suggests, they are drawn to the fungus that can develop in the moist soil of your potted plants instead.
Although fungus gnat adults don’t harm plants, their larvae feed on the delicate roots of the plant and can eventually make it wilt. Injurious fungi can also be carried by fungus gnats.
I have potted plants, how can I get rid of the gnats?
Fortunately, there are several of organic and chemical-free ways to get rid of fungus gnats from your prized plants. You can use a traditional trap or common household goods like potatoes and dish soap!
Let the Soil Dry
It’s important to remember to let the soil dry out for a few days and refrain from watering your plant because fungus gnats and their larvae prefer to nest in moist soil. The gnats will be forced to live in an uninhabitable habitat as a result, and they will disappear in dry soil. Do not be afraid to skip your next watering in order to get rid of the gnats; your houseplant will be able to endure the dryness for a longer period of time than you might imagine.
The best advice is to take your plant out of the planter and drain any extra water from the bottom. Thus, there won’t be any dampness where gnats might deposit their eggs.
Use Traps
There are numerous traps you may employ to get rid of these bothersome bugs if you’re seeking for a speedier fix. You can choose to DIY these with a few common things or run to the store and buy specialist traps, depending on what best suits your needs.
- Pour a cup of white vinegar and a few drops of liquid dish soap onto a shallow saucer. The gnats will be drawn to the solution and fall into the trap if you place the bowl near your plant. Repeat the procedure until no more gnats are present.
- Sticky fly traps are an alternative if the smell of vinegar deters you from making your own homemade gnat trap. These little yellow paper sheets attract gnats and trap them with glue because of their brilliant hue. Although it might not be visually appealing, this procedure is simple and safe.
- Consider purchasing an indoor fly-catching gadget if you’re sick and tired of gnats in your plants and need an urgent fix. These are typically USB-powered and can be purchased locally or online. The blowers and LED lights draw the gnats, and eventually they are drawn into the trap.
- Are there any extra potatoes in the kitchen? Set a trap for them! Place the potatoes flesh-down on the ground after cutting them into little pieces. The fungus gnats will be drawn to the potatoes by their dampness. Just be careful that the parts don’t dry out otherwise it won’t operate.
Sanitize and Repot
Consider removing the plant from its planter and scraping out the soil if you want to take matters into your own hands. When doing this, take care not to disrupt the roots and take only what you can get rid of. Put the contaminated soil in a plastic bag and wash the planter with soap and warm water to sterilize it. Repot your plant into new soil after this is finished, then put it back into its planter.
Use a Spray Bottle
Take a spray bottle and combine water and dish soap in it. Repeat the technique until all of the gnats are gone by spraying the solution on the top layer of soil. If you’re seeking for a quick and natural solution to get rid of fungus gnats, try this.
On Monstera, how can you get rid of the little flies?
The even smaller worm-like larvae, which feed mostly on algae, fungi, and decomposing plant materials in the soil, hatch from eggs placed in the soil. They also consume plant roots, which, in sufficiently big infestations, can harm plant roots and even cause withering or yellowing of plant foliage.
I believe that altering the environment will make your pots less conducive to fungus-gnat-larvae life. This entails watering a little less frequently and allowing the top inch or two of soil to become dry.
It’s ideal for egg hatching and larvae survival to water frequently and maintain the soil’s continual moisture, even at the surface.
The majority of houseplants can survive with just one weekly bath. It’s not a problem if the surface inch is dry but the rest is damp because the objective is to maintain the root zone’s moisture.
Even better, cover the soil surface with a half-inch to an inch of sand. This dries down very rapidly, and adult fungus gnats don’t appear to enjoy laying their eggs on a sandy surface because of how itchy it is. It’s a simple, affordable strategy that has been really effective for me over the years.
A researcher from Kansas State University discovered another handy tip when they discovered that Bounce fabric softener sheets were quite effective at keeping fungus gnats away.
The sheets can be spread on top of the soil to prevent further egg laying because they contain a variety of compounds that repel insects. I think different brands will also function.
Trapping the flying adults with yellow sticky cards is a third attack strategy. Yellow attracts fungus gnats, which are easily collected by sticky substances (a la fly traps).
Gnat Stix and Safer Houseplant Stick Stakes are commercially available traps, but you can also construct your own by affixing yellow cards to sticks, covering the sticks in petroleum jelly, and pinning the sticks around the pot’s sides.
If everything else fails, you can kill the larvae by soaking the soil in a solution containing Bti (Bacillus thuringiensis var. israelensis) or another insecticide that is approved for use on indoor plants to prevent fungus gnats.
In Monstera, how can you get rid of bugs?
When caring for your indoor Monstera, it is imperative to take your growing space into account. The majority of houses and workplaces are enclosed, meaning that there is little to no ventilation and lots of interaction between your plant and those in the vicinity.
You don’t want to poison the adjacent residents in addition to the pests! Here’s how I handle insect infestations in a way that won’t harm you or your Monstera.
Handpicking
Sometimes the most straightforward answer is the best one. Simply remove the insects from your plant! A cotton swab drenched in diluted alcohol can kill any bug. Simply use a moist cloth to wipe the bug away.
This works against various pests in addition to mealybugs, where it is particularly effective. Thrips and aphids can be wiped away with a damp towel, while scale bugs can be removed using your fingernail.
For more serious infections, more extreme measures are needed. Monsteras benefit from rigorous pruning, and any leaves that are infected should be removed and thrown away completely.
Washing
Washing thrips and spider mites off of your Monstera plant with a hose or a showerhead says it all. This is particularly advantageous for Big Monstera because it enables you to fully clean the leaves of dirt, debris, and bugs.
Syringing Plants
This technique entails utilizing an air bulb or syringe to squirt pests with a water jet. It is a great option for the initial stages of an infestation and is equally safe for you and your plant. It is a wonderful option for specimens that cannot be relocated because it is a scaled-down version of showering your plant.
Sticky Traps
Commercial sticky traps are bright yellow in color, which attracts thrips, whiteflies, and adult aphids. (Click here to view Amazon’s price list).
They stumble into the trap and are helpless to get away. They can be regularly checked to see what’s buzzing around, and they’re a terrific preventative step for your collection.
Garlic Spray
If you want to save money, think about creating your own homemade garlic spray. When properly prepared, garlic aromatics are an efficient pesticide.
To make garlic spray, crush three or four garlic cloves and let them steep in a half gallon of water over night. After being filtered, it can be put into a spray bottle and administered straight on leaves.
A few drops of dishwashing liquid may be added to the mixture to aid in the mixture’s adhesion to the leaves. Apply again frequently until the infestation is eradicated.
Chilli Spray
You may use chillies to create a homemade foliage spray that will ward off subsequent intruders, much like garlic spray.
This spray is made by mixing a half gallon of water with three tablespoons of chili powder. To make it stay on the leaves longer, some people like to add a little dishwashing detergent to the mixture once more.
This combo is highly annoying, it should be noted. You must apply a “test patch on your Monstera. A discreet leaf patch should get a tiny amount of application.
depart for the evening. Your Monstera is sensitive to the mixture and shouldn’t be sprayed if the leaf displays symptoms of irritability like yellowing, curling, or splitting.
Diatomaceous Earth
Diatomaceous earth is a common option in this area for a number of reasons. This thin powder is made by finely grinding the fossils of small extinct sea animals.
When the dust settles, it lacerates insects by entering their bodies and killing their organs while also dehydrating them.
This material is absolutely safe for all living things, including children, animals, and plants, to the point where it is occasionally used as a nutritional supplement. (Click here to view Amazon’s price list.)
After watering, I like to sprinkle it on top of potting mediums and dust it at the base of leaves and petioles. It collects in cracks and crevices on your Monstera, enabling it to find pests where they like to conceal themselves.
Essential Oil
Some people are ardent proponents of treating insects with essential oils. Spray peppermint and spearmint oils at a rate of around two drops per ounce of water on the leaves and stems to ward against infestations. All three thyme, cedarwood, and clove work wonderfully.
Horticultural Oil
Horticultural oils kill insects by suffocating them by coating their bodies. Spraying them on the foliage of your Monstera is an efficient approach to get rid of a moderate infestation.
They are a powerful weapon in the never-ending conflict between the gardener and the insect and are available in a number of combinations. They must be treated frequently in order to catch emerging grubs as they hatch because they predominantly attack adults.
Neem oil
Neem oil has something special in addition to the physical characteristics that kill insects, even though it is technically another horticultural oil.
Neem oil includes organic insecticidal substances that are safe to use in dilution to kill and scare away those bothersome insects that like to feed on your Monstera. (Click here to view Amazon’s price list.)
Insecticidal Soap
Another topical spray in the indoor gardener’s armory is insecticidal soap. As the name implies, this soapy spray helps remove waste, including any possible eggs that may have been left behind, and kills adult insects.
Biological Controls
Biological controls could be an effective approach to keep the bugs away from your Monstera if you frequently experience pest issues. Bringing predators into your growing environment is necessary for this.
Although it might seem hopeless, the predators are as little as their prey! Due to their voracious appetites and diverse palates, ladybirds are a fantastic choice because they will target nearly any insect that makes its way into your growing environment.
Pyrethrin and Pyrethroid Insecticides
Of course, there are circumstances in which you must use extreme measures. A naturally occurring substance called pyrethrin that is effective as an insecticide is found in daisy blossoms. Its synthetic cousin, pyrethroids, is equally potent and both can be applied to your indoor Monstera without harm.
As with all pesticides, they ought to be applied sparingly and only as a last resort. Before using these insecticides, consider your other options because overuse can breed pests that are resistant to them.
Disposal
Sometimes it’s best to give up and eliminate a diseased plant from your collection completely. By separating the bugs from the Monstera, pests are kept at bay. Even if it’s difficult to let go of a prized property, the effort is definitely worth it.
Never compost an infected Monstera plant. Throw everything, pot and all, straight into the trash. Reusing the soil or the pot could encourage the infestation to find new hosts.
This contains lesser quantities of soil, pots, cuttings, and maintenance tools. Prunings that are infected should be thrown away by double bagging and throwing them in the trash, and shears should be sanitized in between uses.
Cultural Changes
By altering the way you take care of your Monstera, you can get rid of insects and keep them from coming back. For example, letting your soil to dry between waterings and increasing humidity both kill spider mites and fungus gnats. The ability of your tasty sweetie to ward off pests on their own is greatly improved by proper maintenance.
