You can read the answers to some of the most often inquiries I receive concerning pest management for houseplants below. After reading this page and the FAQs, if you still can’t find the answer to your question, put it in the comments box below and I’ll respond as soon as possible.
What is eating my indoor plants?
Most household pests that feed on plants extract the sap from the leaves. Therefore, if you discover holes in the leaves or notice that some of the leaves are being eaten, another bug is to blame. To identify the offender, carefully examine the leaves.
What can I spray on my houseplants to kill bugs?
For washing the leaves, I suggest using organic insecticidal soap or a gentle liquid soap. For long-term organic pest control, treat the plant with neem oil (a natural insecticide for houseplants).
Because indoor plant pests might develop resistance to synthetic pesticides, always use a natural pest control spray.
How do you kill bugs in potting soil?
There are a few techniques you may use to get rid of bugs in a bag of potting soil. Put the soil bag outside if you live somewhere chilly and wait for it to totally freeze.
If not, keep your unused potting soil sealed up in a container. It works excellent to use a simple 5 gallon bucket with an airtight lid.

What should you do if pests are present in your indoor plants?
These are the tiniest, pearshape insects that you have undoubtedly seen in the vegetable patch outside. They can be found on indoor plants as well, and they tend to congregate around developing leaves and flower buds. They produce a gooey fluid known as honeydew after sucking the plant’s sap.
Remove any areas of the plant that are seriously affected to get rid of the bugs. Use a damp cloth to remove insects from other places, or use the bathtub to spray them with water. A cotton swab dipped in rubbing alcohol, vegetable oil, or insecticidal soap can also be used to remove them. Weekly removal should continue until they are gone.

The most prevalent (and bothersome) pests that affect indoor plants are fungus gnats, often known as soil gnats. I’ll thus tell you everything there is to know about them in this piece and demonstrate how to do so FOR GOOD.
Fungus gnats can infest any plant that is growing in soil, which is their worst quality. Which implies they can access each and every one of your indoor plants, assuming you have any.
When you water your plant or otherwise disturb the soil, you will see these indoor plant bugs crawling out of the potting soil or fluttering around your plant. Yuck!
There is no denying that they are an extremely unpleasant pest! However, there is good news: you can get rid of them and prevent them from returning to infest your houseplants.
How do the bugs get on my houseplants?
Indeed, indoor plants draw insects. They are typically drawn to indoor growing environments with high humidity levels or little air movement. The most common pests are aphids, spider mites, fungus gnats, mealybugs, scale, thrips, and whitefly.
Infestations can be kept to a minimum and treated immediately, causing the least amount of harm to your plants, by keeping ideal growing conditions, providing adequate water, and examining your plants frequently.
If you are reading this, there’s a good chance that you already have some bugs and are looking for information about them. You’re fortunate!

How Can I Naturally Get Rid of Bugs in the Soil of a House Plant?
- Use a three percent hydrogen peroxide solution in water to thoroughly water the plants.
- Add some diatomaceous earth to the soil’s surface and the saucer of the pot.
- Put the plants somewhere well-ventilated, and let the soil dry up entirely.
I have pests on my plants; how can I get rid of them?
All of us adore our plants! We don’t! They are like a second family to us. When we observe a healthy plant going through some strange changes, it makes us unhappy. Do you wish to keep your plant in good health? Or, are you having trouble with an ailing, hurt, or diseased plant? Your indoor plant has probably been attacked by bugs. Other plants may become swiftly affected by the issue. Here are some practical solutions to the issue that will assist you. With the help of the answers offered here, you can create your own DIY pesticide using items you likely already have on hand. This handy pest & illness aid guide from our plant experts is perfect if you love your plants. Due to nutrient deficiencies, plants can occasionally display indications of illness; we will explore this in a later post.
The greatest strategy to control pest activity is to provide your plants the finest care possible. To thrive, all plants need food, water, and sunlight, yet different plants have varied needs for each. Check the care label and adhere to the directions for new plants. Lack of sunlight and sickly, overwatered plants attract gnats, other insects, mildew, and bacteria. Spider mites and insects from arid climates thrive in conditions brought on by underwatering plants. Sometimes all it takes to solve a bug issue is to get the proper soil moisture balance.
Always remember to wash your plants’ leaves once every week. Additionally attracting and harboring spider mites and other insect pests are dust and filth. Plants covered in dirt and dust not only appear ugly, but they also suffer health-wise. Why? Because dust restricts the ability of plants to breathe by clogging the pores on their leaves. Additionally, before the sunlight reaches the plant, dust partially filters it. The plants’ health is negatively impacted since the amount of photosynthesis is significantly reduced.
Use an organic fertilizer to consistently fertilize your plants at regular intervals. To remove all useless plant parts and to promote plant growth, make sure you also trim and prune the plant.
Keep a close eye on your plants to spot any pest or disease attacks. Always look for insect or disease indicators on both sides of the leaves as you water your plants. Check the stem for any observable modifications and symptoms as well. Learn how to spot plant pests like mealybugs, scale insects, mites, aphids, caterpillars, and more.
Treat plants appropriately if you notice any pests or damage caused by pests, such as chewed or stippled leaves, insect droppings, sticky foliage, or webbing. Later on, we’ll talk about how to treat plants at home with various pests.
Isolation is the best first line of defense. Your plant may become infected or succumb to a disease, which can then quickly spread to other plants. Isolating the plant for a few weeks should be your first move if you have any suspicions. Until the issue has been resolved, keep it apart from your other healthy plants. Try some straightforward home treatments first, then break out the drugs.
Dishwashing soap, shampoo, rubbing alcohol (surgical spirit), and vinegar are just a few of the many safe household chemicals that you can employ, but before using one of them, you must first determine what the issue is.
Larger insects can be manually removed using tweezers or your fingers. Try spraying them with a stream or spray of water from the hose to get rid of insects that are simple to move, such as aphids, crickets, mites, or spiders. Water pressure will cause them to fall. Try making your own soap solution if this doesn’t work for your plant.
For all insects, homemade soap solution is effective. 1 liter of water and 1 teaspoon of baby shampoo are combined. Spray it liberally on the plant after thoroughly mixing it. Avoid spraying outside in the sun. Always wash the plants with fresh water after 3–4 hours of treatment to prevent damage. Do a test on a limited region at all times. To check for damage, wait two to three days. On plants with hairy leaves and plants with waxy leaves, avoid using soap. Use regular shampoo if baby shampoo is not readily accessible (only half teaspoon in one liter). Vinegar is largely accessible in every household. Spraying the plant with a solution made of three table spoons of vinegar and one liter of water will effectively ward against pests.
On aphids, spiders, mites, thrips, whiteflies, lacebugs, scale, and mealybugs, the oil and soap mixture is quite effective.
Aphids resemble tiny, tapering bugs with a variety of colors, including orange, brown, green, and black.
People frequently mistake them for ants. Important: To prevent damage, wash your plant with fresh water 3–4 hours after the treatment.
At first impression, white flies resemble grains of rice. Check the undersides of leaves, especially the lower leaves, for white fly eggs, and gently wipe them away with a damp, soapy sponge (use one teaspoon of dishwashing liquid in one liter of water) (grayish-white ovals). To get rid of the new whiteflies developing from pupa, repeat the application every three or four days. You might also try mixing one liter of water with one teaspoon each of baby shampoo or dishwashing liquid and cooking oil to spray on the plants. Use a yellow plastic container coated in petroleum jelly to catch whiteflies.
A mealy bug infestation may be beginning if you notice a cottony buildup under the leaves, at the site of new growth, or on the stems.
The bugs appear later; they are not noticeable at first. Rubidicone, often known as surgical spirit, can be used to treat a minor mealybug or scale infestation. Apply the rubbing alcohol-soaked cloth or cotton swab immediately to the troublesome regions. Test a leaf before treating the entire plant because some plants with fuzzy or very thin leaves will be harmed by contact with rubbing alcohol. To stop the alcohol from burning the plant portions, you might also dilute it. A mealybug infestation may appear as fluffy or white cottony attachments to the plant component. Typically, citrus, grapes, mannihot, and gardenia are infested by mealy bugs. After being treated with Mealybugs, plants should be segregated and carefully monitored for symptoms of re-infestation. Any new pests should be eliminated until the population has been entirely eliminated.
If there are no observable insect activities on your plants, there is a larger likelihood that the plant has succumbed to a fungus. Plants with fungal infections lose their vigor and vibrant colors and progressively deteriorate over time. Look out for warning indications including patchy, discolored leaves and stems or a change in leaf form. Try using a baking soda and dishwashing liquid mixture for plant illnesses including powdery mildew (a condition in which leaves, especially new leaves, become twisted or curled and are covered with a white powder), botrytis (grey mold), black spot, and other fungi. Mix one liter of water with a half-teaspoon of baking soda and a few drops of dishwashing liquid. Spray the foliage with this mixture. This also requires an after wash with fresh water after 3–4 hours of application, as described in other treatments.
Roses frequently develop black patches and powdery mildew. If you notice any signs of a fungal infection on a plant part, you should remove it right away, carefully, and don’t forget to isolate the entire plant for treatment.
Neem is a miracle cure for plant illnesses and pests. Neem leaves should be boiled in water before being cooled and sprayed over plants. Neem oil can also be used for the same purpose. There are also commercially available insecticidal sprays made from neem.
It could be necessary to repot your plant if there is a significant infestation. Take your plant outside and tend to it while working over a trash bag if this is the situation. Shake off as much soil as you can from the plant before removing it from its container and placing it in a trash bag. Keep other plants’ soil from touching yours. To get rid of as much soil and insects as you can, run the plant’s stems, leaves, and roots under running water. Use a new pot or cleanse your existing one well with soapy water and a soft brush. Use sterile potting soil while repotting. By adding boiling hot water to the soil, you can prepare it to be weed-free. To avoid harming both the plant and yourself, take care while doing this. All weed seeds and other plant life are destroyed by boiling water. Vinegar works well to kill weeds. Repotting is advised once a year for plants that develop quickly.
If your plants respond well to repotting, make time to check on them frequently to make sure the infection hasn’t returned. Following treatment, treated plants should be kept apart and constantly monitored for symptoms of re-infestation, with any new pests being eliminated until the population has been entirely eliminated.
We hope that after reading all of the above advice, you are now prepared to recognize and combat the insect invasion on your plant. Sometimes that extra attention is necessary for your plant friend to thrive and grow healthily. Take care of yourself and your “nature companion”!

Should I discard the gnat-infested soil?
Gnats are annoying because they dare you to capture them as they dart around silently and frequently within a few inches of your face. The fungus gnat, however, can be the most annoying insect of all if you love plants. Fungus gnats can grow quickly in indoor plants and lay their larvae in the potting mix’s top layer, even though they are safe to people. During the winter, these bothersome gnats might be transported within from outside plants. But more often than not, they come into your house on sick plants you brought home from the nursery or garden center. They enjoy hiding in extremely soggy soil that is rich in decomposing plant materials. Once established in one plant, they simply move on to other ones close by, where their larvae contentedly await birth in the first inch or two of soil. The main source of nutrition for larvae is fungi found in the soil, but they can also consume root hairs. The infestation keeps expanding as a result of the adults producing eggs and proliferating. But don’t worry; you won’t have to throw out any of your plants to get rid of fungus gnats. Allowing the soil of afflicted plants to totally dry out will kill the larvae if the infestation is new. However, if the infestation is getting worse, you’ll need to take more drastic measures. Sticky paper might be used to catch the adult fungus gnats, but the larvae that are laying eggs won’t be destroyed. I’ve discovered a simple, secure two-step home fix (sidebar, right) that completely solves the issue. Sand, many tiny saucers, and a delicious, fruity beverage—for the bugs, not you—are all that are required.
Steps to gnat-free
First, construct the sand trap. Get rid of the already-hatched larvae by gathering all affected houseplants and removing the top 2 inches of potting soil. The dirt should be thrown away right away, and its top layer should be replaced with sand instead, which dries up rapidly, is organic-free, and is not a good spot for fungus-gnat eggs to hatch. Before the following watering, allow the soil below to totally dry out. This should destroy all fungus-gnat larvae present and stop the laying of fresh eggs.
Set up the open bar in step two. It is simple to entice and drown adult fungus gnats using any sweet liquid that has a decaying odor. One of the most effective and affordable fungus-gnat lures I’ve discovered is a lovely $2 bottle of alcohol-free wine from Trader Joe’s. Place a tiny saucer with the liquid in it next to a previously affected plant (or by all infected plants if the infestation is already rampant). You should wake up to a disconcertingly pleasant collection of dead fungus gnats floating in the liquid if you let it sit overnight. The saucers should be discarded and refilled until no adult gnats are seen.
