When you are bitten by a mosquito, the itchy effects last for a few days before you may resume your normal activities. But when bugs come into contact with your prized indoor plants, the scenario can swiftly go from Zen garden to complete chaos. Fortunately, not all hope is lost when pests attempt to harm your young plants. You can produce a spray to kill everyone using just three basic materials.
All you actually need is some insecticidal soap to keep pests from taking over your healthy home (and your life!). According to Apartment Therapy, the nontoxic remedy eliminates tiny, soft-bodied pests like mealybugs, aphids, spider mites, and whiteflies while also preventing them from destroying your precious plants. Although you may buy insecticidal soap, making your own is so simple that you might as well do it yourself and save a ton of money in the process.
All you need is water, 1 tablespoon liquid dish soap that doesn’t contain bleach, degreaser, synthetic colors, or scents, and 1/4 cup vegetable oil.
All you need is water, 1 tablespoon liquid dish soap that doesn’t contain bleach, degreaser, synthetic colors, or scents, and 1/4 cup vegetable oil. Simple, huh? Fill a spray bottle to the brim with warm water and shake the contents after adding the dish soap and vegetable oil. After that, you can spray the mixture directly onto your plants once a week until all of those pesky crawlies have been completely eradicated.
Can I use insecticide on houseplants?
Homemade bug sprays can nonetheless harm the plant if not applied properly, while being generally less toxic and safer to use than commercial pesticides. Water the plant and test the combination on a small section of the foliage before applying the homemade sprays to the houseplant. Use the bug spray as necessary if there is no harm to the treated area after two to three days. Avoid placing the houseplant throughout the treatment in regions with strong sunlight or temperatures above 90 degrees Fahrenheit. Burnt foliage, stems, and flowers can result from insecticides of all kinds coupled with strong sunlight, high temperatures, and insecticides.
How frequently should I bug-spray my indoor plants?
— Submitted by:
Our houses benefit from the natural beauty and improved air quality provided by indoor plants, but they also present a breeding ground for pests. These annoying creatures will grow rapidly if no action is taken, destroying your organic décor in the process. There are five typical pests that enjoy houseplants or the soil they live in, and there are practical ways to get rid of them.
But first, let’s review some general guidelines to avoid introducing pests to houseplants in the first place:
- Bringing Home a New Plant – When buying a new plant, keep an investigative watch on it. Check it thoroughly for indications of infestation. Insects may not always be visible if they are still in the early stages of development, but every time you find one, you avoid bringing it home.
- Contaminated Soil – It’s crucial to store unused potting soil in an airtight container to prevent pests from settling in the soil and accidentally infecting your houseplants when you repot them.
- Bringing Plants Inside and Outside – It’s the first gorgeous Spring day, and you want to give your plants a break from their wintertime confinement by letting them enjoy some time outside. Nothing inherently wrong with this situation. Just be sure to inspect your houseplants for bugs and treat them before bringing them back inside.
- Produce and Cut Flowers – Regrettably, we have no control over the treatment of the plants that produce or cut flowers come from. This implies that they might have a pest problem. Again, research is essential. Also, wash all produce well as soon as you bring it into the house.
Let’s now go into the specifics of how to manage these pests:
Mealybugs
These sneaky little suckers will surprise you. When they are first developing, they are essentially unnoticeable, but suddenly, you notice fuzzy whiteness at the bases of the leaves, and if you don’t do anything, it spreads throughout the entire plant. Spraying them with a solution of rubbing alcohol and water in an amount of 1 to 3 parts is the best technique to get rid of mealybugs. When you spray them, their exoskeletons are shattered, and they turn brown, indicating that they are no longer alive. However, continue spraying once or twice a week until you are certain that no more eggs are hatching and you won’t be caught off guard once more. Just keep in mind to cover the entire plant, including the bases and undersides of the leaves, when applying any mixture to indoor plants.
Whiteflies
Whiteflies are simply a pain. Mealybugs are present if you come into contact with a houseplant and a white “mist” surrounds you (and in your nose and mouth). Spraying a solution of 1 teaspoon dish soap to 1 quart of water will get rid of these nasties. Unfortunately, once you disrupt the plant, the adults fly away, so the spray only kills the eggs and nymphs. However, if you continue to spray consistently, they won’t be able to breed, and the adults’ life cycle will eventually come to an end.
Gnats
The easiest strategy to prevent gnats from congregating around your houseplants is to avoid letting decaying plant matter accumulate on top of the soil and to water sparingly so that the soil doesn’t stay wet for an extended period of time. However, you can begin watering the soil with a solution of 1 teaspoon Pine-Sol to 2 quarts water if you’ve found that fungus gnats are residing there. The gnats may take a few weeks to disappear, but this strategy does work. Sticky strips that you can lay on top of the soil are also an option if you don’t like the scent of Pine-Sol. However, this doesn’t actually alter the soil’s ecology. It is a useful method for capturing the adults and preventing them from producing eggs, though.
Scale
These objects don’t even resemble bugs. They resemble unassuming lumps that could be mistaken for growth flaws on any portion of a plant. until the entire plant is covered in them, that is. Although one of the most difficult bugs to get rid of, there is still hope. While early stage scale infestations can be controlled with rubbing alcohol and a cotton swab, the best course of action for scale is to act as though it’s the greatest pest infestation you’ve ever seen because it soon will be. Your best bet in this situation is an oil-based insecticidal spray, such Neem oil. Neem kills scale insects by suffocating them to death, and that’s what you want, right? Neem is non-toxic to people and dogs.
Spider Mites
The terrible spider mite, ahh. You initially assume you’re just neglecting to dust since you notice what appear to be cobwebs on your houseplants. Surprise! That is a spider mite making a damaging web on one of your helpful plants. These are also tenacious pests that can be challenging to totally get rid of, but it is possible. You need to quarantine this infection and keep it away from other plants. Some claim that a soap mixture containing insecticides may kill spider mites, but I advise against wasting your effort. Straightaway reach for the Neem oil (which every owner of houseplants should always have on hand), thoroughly treat the plant, rinse off any webbing and dead insects, spray again, and restrict that plant to its own room. Continue to be attentive by spraying twice weekly until you no longer notice webbing or tiny, spider-like objects.
Indoor plants bring the outside inside. Due of this, we adore them. Nature and bugs go hand in hand, but they also provide natural beauty and purify our air. However, they are non-toxic strategies that we have discovered to be highly effective. Thomas Pest Control is here to assist you if you have any queries or worries about pest infestations.

Why are the bugs on my house plants there?
I’ll address some of the most frequent inquiries I receive about fungus gnat control in houseplant soil in this section. Ask your query in the comments section if you can’t find the solution here.
Will treating the soil with hydrogen peroxide kill fungus gnats?
Hydrogen peroxide application to the soil may be effective in eliminating fungus gnats. Try moistening the top inch of the soil with a solution made by combining 1 part hydrogen peroxide to 4 parts water.
Pouring or spraying it on top are both acceptable options. Remember that the adult gnats that are flying around won’t be killed by this; only the larvae that are dwelling in the soil will.
Controlling the amount of water you provide indoor plants is the most crucial thing to keep in mind while trying to get rid of fungus gnats.
Keep in mind that fungus gnats like damp soil to breed, and that overwatering is the leading source of gnat infestations in indoor plants.
Even if you are successful in getting rid of a fungus gnat infestation in your home, further issues are challenging to stop. Fungus gnats are one of the houseplant pests that are easiest to manage, which is excellent news.

How can you eradicate tiny gnats from indoor plants?
We plant lovers don’t want to witness plants being harmed by pests. The problem enters our homes, which is gross, therefore we especially don’t want to see pests in our houseplants! Fungus gnats are pesky, winged insects with little wings that resemble mosquitoes and are about the size of fruit flies. The good news is that compared to many other pests, these plant flies cause significantly less harm, and even better, they’re rather simple to get rid of.
Long legs, transparent wings, and a preference for nutrient-rich, damp soils are characteristics of fungus gnats. These little flies may be seen flying around plant containers, but unlike some more dangerous pests, you won’t observe them actually chewing on the plant’s foliage. However, you will see them in the soil, feeding on the organic matter and hairs from plant roots. Do not underestimate the damage that these bugs can still do if not addressed.
Even though adult fungus gnats only live for about a week, they can have a big impact in that short time by producing up to 300 eggs under the correct circumstances. With such a quick turnaround and a brief life cycle of about 3–4 weeks, populations can grow incredibly quickly.
It’s rather simple to tell if your plant has a fungus gnat issue. Since these plant flies can’t fly very well, they usually stay rather near to the plant. They’ll probably be moving in zigzag patterns while you watch them. It’s typical to witness all the different phases of this bug at once because they reproduce so quickly. It’s likely that some bugs still in their larval stage will be visible if you gently agitate the soil. They inhabit the earth where they eat organic debris and have translucent bodies and glossy, black heads.
Our plants are getting ready to settle in for the upcoming cold season as winter approaches here in North Dakota. Unfortunately, that signals that these pesky bug populations are about to reach their peak. During this time, dormant plants use less water, which causes their soil to stay moist for longer. Gnats thrive in moist soils because they promote root rot and fungus. Be cautious when bringing delicate plants inside to overwinter since you run the risk of inviting unwelcome pests into your house.
Your plants will start to exhibit signs of stress if ignored and neglected. Fungus gnats don’t directly harm plant leaves, but they eat the root hairs and deplete the soil of vital minerals. This may result in abrupt plant withering and yellowing of the leaves, sluggish development, and a general decline in vigor.
When tackling any pest, you should always start with natural management approaches. The least hazardous and disruptive to your plant and house are typically natural and organic remedies, while chemicals may occasionally be required as a second line of defense. Fortunately, most fungus gnat populations may be controlled and eliminated naturally provided they are discovered and dealt with in a timely manner. Remember that one plant container can hold three to four generations of bugs, so you’ll probably need to apply your favorite approach more than once. Gnats in your indoor plants can be managed in the following ways:
Do not overwater. Before watering your indoor plants, allow the top couple of inches of soil to dry up. This will not only stop fungus gnats from deciding that your plant would make the best place for them to live, but it will also interfere with their reproductive cycle and assist to reduce populations that have already moved in.
Activate sticky traps. Not just for mice, either! Sticky traps are easy fixes for many pest issues. Gnats that are moving will be caught if you place them immediately on the soil’s surface. To stop them from laying eggs, remove them from the trap, discard them, and replace it frequently (every two to three days). Particularly effective at drawing these insects, yellow traps are.
Create vinegar and cider traps.
Mix equal volumes of cider and vinegar in a shallow dish or can to act as a trap for fruit flies. Lay the trap on the soil surface inside the container or even next to the damaged plant. The concoction will attract the bugs, who will then fall into it and drown.
Bring in useful nematodes. Although it may seem counterproductive to introduce additional bugs into the equation, doing so is a simple way to reduce pest numbers. Nematodes are incredibly minute, worm-like insects that are frequently invisible to the unaided eye. In their larval stage, they attempt to infiltrate fungus gnats and other insects, releasing a bacteria that eventually consumes the pest from the inside out. When you think about it, it’s awful and disgusting, but not as disgusting as allowing gnats to devour your prized houseplants!
If all else fails, there are always insecticidal goods and sprays to keep pest numbers under control. There are many products available that either target the adult stage or the larval stage, but either is OK. You should be able to get rid of these unpleasant plant flies in a few of weeks as long as you successfully target one phase of their life cycle and reapply often.
Larvae are easily eliminated with hydrogen peroxide since it kills them immediately upon contact. Infuse your soil with a solution made of four parts water and one part hydrogen peroxide.
To destroy larvae, neem oil can also be put to the soil after being diluted with water. Neem oil can also be sprayed on surfaces to instantly kill adult flies. Last but not least, pyrethrin sprays contain extracts that are harmful to a variety of pests and can instantly kill flies and fungus gnat larvae.
Fungus gnats can affect the health of your houseplants even though they don’t transmit any diseases that are dangerous to humans. Your plants will thank you by giving off a lush, healthy appearance to enliven your home if you keep pests at away.
