To prevent other plants in the area from becoming infected, quarantine the plant immediately if you spot scale on it. If a portion of the plant has a lot of scale on it, you can decide to trim it off rather than treat it.
Due of their hard shells and perseverance in sticking to the plant, scale is resistant to numerous spraying procedures that are effective on many other houseplant pests. The simplest technique appears to be manually scraping them off the plant, however this might be tiresome if your Monstera has a lot of scale.
A tried-and-true technique for getting rid of these pests is to use a cotton swab dipped in rubbing alcohol and applied to the scale. The alcohol dissolves the insects’ shells, quickly killing them. With this approach, you will need to be watchful, making sure to cure any visible scale insects and checking for fresh ones every few days. Because they swiftly reproduce, any insects that are left behind must be eliminated.
Manual removal typically works for scale concerns that aren’t too severe. There are a few viable choices for this as well, though, whether your attack is on a larger scale or you prefer to start with systemic tactics.
Horticultural soap, often known as insecticidal soap, is available for purchase or can be made at home using a few basic materials. Once your collection of indoor plants reaches a certain size, I believe horticultural soap becomes a need. Since it is safe for pets, birds, and beneficial insects and doesn’t leave behind the unpleasant residue that certain insecticides do, it is preferable than genuine pesticides.
In case you decide to make your own horticulture soap, I’ve provided a couple recipes below, along with usage instructions.
Thrips
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!

Identification
Over its leaves, your monstera’s stem and leaf joints will be most frequently attacked by scale insects. The scale insect will have a flat, rounded appearance and be quite small in size. Leaf drop, yellowing leaves, and white and yellowish blotches on the leaves, stems, or branches are indications that your plant is being attacked by scale insects.
Treatment
Scale insects are easily handled using natural techniques. To prevent the spread of scale to surrounding plants, it’s crucial to separate the plant. You can use a few items to attempt and get rid of scale. These include rubbing alcohol, homemade or organic insecticidal soap, and neem oil. If possible, you can also try cutting the affected portions off.
In addition to being a bothersome pest while growing vegetables, grasshoppers are well recognized for being lean, green plant-eating machines. However, they can also seriously harm the foliage of your monstera. Only when your monstera is kept outside can grasshoppers pose a risk; otherwise, it should be safe inside.
However, if you still want to leave your monstera deliciosa growing outside, you may either manually remove grasshoppers or use insecticides. Removing your plant from the outside should eliminate the possibility of your monstera being devoured by grasshoppers.

Does Monstera entice insects?
For any budding indoor gardener, monsteras are an ideal first plant choice because of their reputation for pest resistance. It is simple to take Monstera’s hardiness for granted, but pest resistance and pest-free are not the same thing. Finding out that your formerly impregnable showcase has been eaten to death by small intruders can be extremely shocking!
Aphids, thrips, whiteflies, and fungus gnats are the pests that attack monstera the most frequently. Change your care procedures to prevent future infestations and manually eliminate pests from your Monstera. Topical treatments can range from over-the-counter medications to more potent pesticides that should only be used in the case of serious infestations. Whatever therapy you select, your Monstera is tough and will bounce back swiftly.
What is sprayed on the leaves of Monstera?
Cleaning monstera leaves with distilled or purified water, a little non-detergent soap, and a microfiber cloth is one of the simplest methods.
To clean the leaves, first mist them with distilled water and let them sit for around five minutes. Any trash or other crud on the leaves will become looser as a result.
Use a half-gallon of distilled water and a teaspoon of detergent-free soap (we recommend Dr. Bronner’s pure organic castile soap) to soak your microfiber cloth. Start cleaning the tops and bottoms of the leaves very gently, being careful to hold the opposite side of the leaf in place with your hand. Here, take your time to avoid accidently breaking, cracking, or scratching the leaves.
After thoroughly wiping each leaf, give them a gently rinse in the shower or with a hose spray.
To prevent the soap and water from dripping into the soil, you might wish to tilt your plant to one side.
To keep your leaves clean and healthy, we advise doing this at least once every few months!
Are bugs a problem with monstera?
Monstera plants can be harmed by mealybugs, scale, spider mites, bacterial leaf spot, root rot, and anthracnose. These problems can be solved using a variety of techniques, including as repotting, horticultural oil, and pesticides. However, a perfect growth environment is the best defense against pests and illnesses.
What does monstera’s thrip damage look like?
Monstera plants are beautiful and relatively easy to care for (for the majority of kinds, at least), but like most houseplants, they are prone to pests like scale, mealybugs, spider mites, and thrips. Everything you need to know about thrips on monstera plants and how to get rid of them will be covered in this post.
Thrips are tiny, wingless insects that might be challenging to spot with the unaided eye. On your monstera’s leaves, they may seem as tiny white, brown, or yellow specks that are in motion. These nasties could appear on the tops, bottoms, or even stems of your plant.
The largest species only grow to a length of 1.5 to 3 mm. Despite the fact that there are thousands of different thrips species worldwide, yellow or black thrips are probably the most common ones you’ll notice on a monstera plant.
Thrips are particularly tenacious since they procreate quickly and eat the sap from the leaves of your monstera. When mature female thrips drill a tiny hole in the leaf tissue to lay their eggs, the leaves are immediately harmed. After a few days, the young, or nymphs, will hatch and begin sucking the fluids from the leaves, which further harms them.
In their roughly 45-day life cycle, thrips have the capacity to lay over a dozen eggs. What a large number of bugs! This is why it’s critical to identify and treat thrip infestations as soon as possible.
Let’s discuss how to spot thrips, thrip damage, and what to do if you notice these symptoms in order to rescue your plant.
Why do the little holes in my Monstera exist?
In the past, other people have expressed the opinion that spots and holes like those might be caused by moisture droplets on the leaves being overheated by the sun, which causes tiny surface burns on the leaf tissue.
Use Water to Remove Them
You can soak the entire plant in water to get rid of the aphids if the plant’s fragile leaves won’t withstand spraying. Flip the plant over and submerge the foliage in a pail of fresh, room-temperature water.
Try Insecticidal Soap
You can buy insecticidal soaps (like Safer’s Insecticidal Soap) or make your own by mixing Ivory Liquid dish detergent with water. Look for a product devoid of chemicals and scents that could hurt plants.
Water should be combined with soap at a low concentration (starting with 1 teaspoon per gallon and increasing as necessary). Spray plants, paying special attention to the undersides of the leaves.
Use Neem Oil
Neem oil is 100% organic because it is made from neem trees. Use as directed by the label. Neem oil works as an insect repellant and alters an insect’s ability to feed. Neem is safe to apply on both ornamental and edible plants, according to the Environmental Protection Association.
Use a Homemade Spray
One garlic bulb, one small onion, and one teaspoon of cayenne pepper should be processed into a paste in a food processor or blender to make a batch. Steep for an hour after mixing into a quart of water. Add 1 tablespoon of liquid dish soap after passing the mixture through a cheesecloth. Mix well. The combination can be kept in the refrigerator for up to a week. Aphids can be controlled by two more forms of DIY sprays.
Tip
The “Rodale’s Organic Gardener’s Handbook of Natural Insect and Disease Control” describes the all-purpose insect spray that the editors of Organic Gardening magazine created.
Use Sticky Traps
Any insects that come to visit your plants will be captured by sheets or strips of sticky paper strung around them. Both garden centers and online vendors sell sticky traps.
Use Chemical Sprays
If a serious infestation of a treasured plant leaves you with no other choice, try low- or no-chemical remedies first, but if those fail, treat the infestations with a spray that contains pyrethrins, imidacloprid, or pyrethroids. Consider using low-toxicity sprays with pyrethrin bases to reduce potential injury.
How are indoor plant bugs eliminated?
When Acree returns home with a fresh plant, she immediately disposes of any pests by placing it in the bathtub. She tops the soil with pet- and kid-safe food-grade diatomaceous earth powder, which dries out the insects and their larvae, after lightly misting them with a natural DIY bug repellent that you can prepare with 1 tablespoon of tea tree oil and 1 cup of water.
Spray your plants
Making an insecticidal soap to spray on your plants is your best option if you’re dealing with soft-bodied pests like mealybugs, aphids, whiteflies, and spider mites. While you may purchase one at the shop, it’s simple to make a DIY version with organic ingredients. Simply combine 1 Tbsp liquid dish soap (free of bleach, degreaser, synthetic colours, and scents), 1/4 cup vegetable oil, and 1 Tbsp liquid dish soap in a spray bottle, then top it off with warm water and shake. Once a week, you can spray your plants with the combination to get rid of pest problems.
Dry out your plants
By simply eliminating the moisture, pests like fungus gnats that prefer damp soil in houseplants can be controlled. (Excuse me, gnats.) The best course of action in these types of circumstances, according to Susan Spanger, a professional gardener and floral designer at Bloomful Floral Design, is to water your plants less frequently than usual in order to let the top few inches of soil totally dry up.
You eliminate the source of food for fungus gnats—fungi in the soil—by not maintaining damp soil. The Sill claims that by letting it dry up, that important food source will be eliminated, which will also eliminate the fungus gnats. According to Spanger, you can also cover the top of your soil with a half-inch of sand. She claims that mature fungus gnats find the rough surface unpleasant and that it dries off soon. Those pests on the houseplants will never return.
