These tiny, wingless insects, which when gathered together seem white, are typically found on plant stems, leaves, and nodes (the area where leaves meet the stem). According to Scott, “Mealybugs are drawn to excessive succulent growth, which can be brought on by overwatering and overfertilizing, particularly with fertilizers heavy in nitrogen.” Plant development slows down and leaves often curl and turn a faint shade of yellow as a result of their feeding on plant sap.
By delicately wiping them with a cotton swab dipped in 70% isopropyl alcohol (avoiding touching delicate leaves), or by misting them with a solution of dish detergent and water, you can get rid of the bothersome insects (one teaspoon of soap to one gallon of water). Mealybugs can also be controlled with insecticidal soap, neem oil, and horticultural oil. Follow a planned fertilizer schedule rather than indiscriminate feeding to stop breakouts, advises Scott. Mealybugs can easily be removed with your own hands if discovered in time.
How can bugs in soil for indoor plants be removed?
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.
How can bugs be eliminated without destroying plants?
According to Jeff Gillman, author of “The Truth About Garden Remedies: What Works, What Doesn’t, and Why,” commercial insecticidal soaps are safer for plants than homemade equivalents. Keep it mild if you want to try producing your own. 2 teaspoons of liquid dishwashing soap combined with 1 quart of water yields a 1 percent soap solution. Use a mild dish soap made for hand-washing dishes, not laundry or dishwasher detergent. Aphids, mealybugs, mites, and other soft-bodied pests respond well to soap spray. Additionally, Gillman adds that dish soap aids in preventing powdery mildew.
Why do my house plants have tiny bugs in them?
Numerous little flying insects that resemble gnats have been seen all over a few of my houseplants. How can I get rid of them and what are they?
Most likely, they are fungus gnats. These naughty little creatures are a very frequent pest throughout the winter, and they are more drawn to the damp soil in houseplant containers than to the actual plants.
Most of the time, fungus gnats are an annoyance. The adults can occasionally hover around your face or at the very least give the impression that you live in a greenhouse overrun with insects.
Although the adults resemble little mosquitoes, they don’t bite, sting, or harm plants despite their appearance.
Actually, the larval stage of this bug—the two to three weeks of its life that you cannot see—poses a greater risk to plants.
What can I apply to my plants to spray on insects?
There is no quick fix to keep insect pests away from your indoor plants and garden. I’ve picked up a few tips over the years on how to deal with bugs without using harmful chemicals. Here are some of my suggestions, including some homemade insecticides (soap sprays).
Pay Attention to Your Plants
Consider the following methods to deter insect pests from attacking your plants before using pesticides, even natural ones:
- Use organic fertilizers like aged compost to feed your plants. Strong plants are less likely to be attracted by insects and are better able to survive their attack than weak ones. If you’re using fertilizer, pay strict attention to the directions. Pests will be drawn to overfertilized plants and consume their lush new growth.
- Use companion planting to naturally ward off insects. While some plants coexist well, others do not. Take a look at our companion planting guide.
- To prevent pests from damaging your plants, especially sensitive transplants, use barriers like row covers. When plants are established and in flower, remove the coverings to allow insect pollination. Additionally, placing “collars” made of cardboard from toilet paper or paper towel rolls around the tiny transplants (1 to 2 inches into the soil) may stop pests like cutworms from eating the tender stems.
- Plantings should be timed to avoid bug population peaks. For instance, so as to avoid squash vine borers, which deposit their eggs in the early to mid-summer, sow squash as soon as feasible. To avoid the carrot fly, plant carrots after June 1 and harvest them by the beginning of September.
- Choose plants that have some pest resistance built in. Butternut squash is one of the vegetables I grow a lot since it is quite hardy against the squash vine borer.
- By controlling the bugs they feed on, beneficial insects will do a lot of the work for you if you make your garden inviting to them. For instance, lady beetles are a successful biological pest control for a variety of insects. Leave a tomato hornworm alone if you notice one with white cocoons on his back (see above photo). His body is covered with the eggs of a parasitic wasp, whose young will soon consume him from the inside out. An appropriate end for such a horrible pest!
- Recognize the bugs that inhabit your garden. If you don’t know who is a friend and who is an enemy, you can’t defeat them. To prevent them from becoming adults, become familiar with the appearance of their larvae and eggs.
These aphids have caused some harm, but if you notice black and orange ladybug larvae that resemble alligators attacking the aphids, don’t spray. He can consume up to 50 aphids per day, doing the grunt work for you.
Organic Pesticide Sprays for Insects
Avoid using harsh chemicals if you have tried all other options and feel you must use a spray. They will pollute the watershed, kill both good and bad bugs, and eventually the insects you are attempting to kill may develop a resistance to those poisons necessitating the employment of more stronger ones, which will do more harm than good. They may also cause harm to you, your kids, and animals and birds.
Making one of these homemade insecticidal sprays can help you take a more natural approach. Remember that although being less hazardous, they are not completely safe. Keep children and pets away from them. Before using them extensively, test them on a few leaves to ensure they won’t harm your plants. They will unquestionably cause foliar damage if you sprinkle them on your plants in the hot, sunny part of the day. When bees and other pollinators are not busy in the evening, spray.
- Dish Soap Spray: Mix 1 quart of water with 1 tablespoon of a mild liquid soap, such as castile soap or pure dish soap (no bleach, degreaser, or other additives). Although Dr. Bronner’s soap is pricey, it doesn’t contain any animal fats, making it a decent option for vegans. Soft-bodied insects can be easily killed using insecticidal soaps. Make sure to cover the entire plant, including the stems and both sides of the leaves. Sprays made of soap must be reapplied every 4–7 days or until you see a decline in population because they only operate when they are moist. If rain hasn’t done this for you after a few applications, spritz the plants with plain water to remove any soapy residue.
- Spray with oil: Combine 1 cup vegetable oil and 1 tablespoon mild liquid soap. Spray your plants as before using a quart of water and 2 to 8 teaspoons of this combination. This spray is good against aphids, thrips, mites, and scale because the oil smothers the insects.
- Insecticide from Tomato Leaves: Tomato leaves contain the insecticides solanine and tomatine. 2 cups of fresh leaves should be overnight soaked in 1 quart of water. Spray after sifting. In addition to killing aphids and many eating insects, it also draws helpful insects. Because it may transfer illness from plant to plant, avoid using it on other nightshades like potatoes, eggplants, or peppers.
- Contrary to what you may have read, garlic serves more as a repellant than a killer. Let 2 garlic bulbs and 1 cup of water be pureed overnight. Pour the liquid through a strainer into a quart jar, then top it out with water by adding 1/2 cup vegetable oil, 1 teaspoon liquid soap, and the remaining liquid. Fill a 1-quart sprayer with water, add one cup, and spray the damaged plants. Aphids, cabbage worms, leaf hoppers, squash bugs, and whiteflies can all be repelled by it.
- Hot pepper repellent spray: Hot pepper works effectively on a variety of insects as well as rabbits and deer. Combine 1 quart of water, 1 teaspoon of mild soap, and 1 tablespoon of dried chile powder. Spray the plants being attacked at full vigor.
If you have a lot of hot peppers blooming in your yard, purée 1/2 cup of the chopped peppers with 1 cup of water to create a new mixture. 1 quart of water with the puree added should be brought to a boil. Strain after allowing to cool. Add 1 teaspoon of mild soap, then spray plants at maximum strength. When using this spray, you might wish to wear gloves and avoid getting it in your eyes.
Many other plants, such as hyssop, lettuce leaves, onions, pennyroyal, peppermint, and radish leaves, have also been said to have insecticidal properties.
In terms of pest management, there is no one solution that works for everyone. At most, we can work to keep a good balance between the good guys and the evil guys while still procuring some good produce for ourselves.

Gnats in potted soil: how can I get rid of them?
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.
What are the little insects in my potting soil?
Many individuals have mistaken a fungus gnat infestation for a fruit fly infestation since fungus gnats and fruit flies have similar appearances.
They are not, however, the same kind of issue. In damp soil, fungus gnats deposit their eggs. When the eggs hatch, the larvae feed on fungus, tiny roots, and other organic matter in the soil. Fruit holds little appeal to them.
- Fungus gnats are the tiny, black insects you may notice hovering around your plants and in the soil.
- Fruit flies are the gnats that are buzzing about the fruit or the garbage disposal in your kitchen.
