How To Kill House Plant Bugs

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.

How can pests in indoor plants be removed?

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 potting soil be eliminated?

It’s crucial to get rid of any little, fuzzy gnats that are buzzing around your potted plants. Fungus gnats are bothersome, but it’s the larvae that feed on soil organic matter, including the roots of plants. One part hydrogen peroxide and four parts water are advised by Pistils Nursery. Incorporate the solution into the potting soil. Repeat as necessary at each watering to get rid of the eggs and larvae and get rid of the gnats.

Hydrogen peroxide treatment of soil and hydroponic solutions has also been discovered by growers to be effective in getting rid of root aphids. According to Weedmaps, hydrogen peroxide has had some success when used in conjunction with heat and cold treatments like heaters and water chillers. Exercise caution because severe heat and cold might harm some plants. Additionally, maintain good gardening hygiene by sanitizing spent containers, rotating your plants, and cleaning the hydroponic system and greenhouse.

Hydrogen peroxide therapy offers other advantages. Hydrogen peroxide, a potent oxygenator, decomposes and releases its oxygen into the soil. The roots of the plants receive oxygen and nutrients as a result. Additionally, it has a significant impact on bacteria and fungus, which are eliminated from the soil with every irrigation. Use a solution of one part hydrogen peroxide to two parts water to hydrate the plant and control the fungi that cause root rot, and then wait until the soil is almost completely dry before continuing light watering if overwatering is harming your plants.

How can bugs on plants be killed?

Isolating any plant that may be home to a pest is the first step in pest management. Once the pest is fully under control, keep the plant away from other indoor plants. This procedure could take a few weeks or longer.

There are a number of efficient control options to take into account before resorting to chemical methods to address a pest issue on houseplants. However, don’t anticipate that one application will be enough to address the issue. Some of these solutions call for the indoor gardener to be persistent, but they can provide effective management.

  • Remove and destroy the infected parts of the plant if the infestation is limited to a single area, as is the case with leafminers. If the roots are infected, start a new plant from a cutting. Start by using a fresh pot and sterilized potting soil.
  • Early infestations are frequently easy to eradicate by handpicking.
  • A cotton swab bathed in rubbing alcohol can be used to remove insects like mealybugs and aphids from plants. It could be necessary to use a fingernail to scrape off scale insects.
  • Numerous pests can be eliminated by water-spraying a robust plant. Make sure to spray the entire plant. Spider mites can be managed with frequent water sprays.
  • A pest invasion can frequently be stopped in its early stages by spraying the plant with insecticidal soap. Because they are contact insecticides, insecticidal soaps only work when they come into touch with actual insects. The soap solution loses its ability to repel pests as it dries. The pests that insecticidal soaps work best against are those with soft bodies, including aphids, mealybugs, immature scales (crawlers), thrips, whiteflies, and spider mites. Since pests may be concealed or in the egg stage, getting rid of them frequently requires multiple treatments. For product illustrations and other information on insecticidal soap sprays, see Table 1.
  • The best and simplest option may be to throw away the plant and its soil and start over with a new plant if the plant is worthless and severely damaged.

Is vinegar safe to spray on houseplants?

According to the Alley Cat Allies website, white vinegar has a potent, repulsive smell and taste that can effectively keep cats away from sections of your home that you don’t want them to enter. Despite being harmless to humans and cats, vinegar is deadly to plants due to its 5% acetic acid content. According to the Northwest Center for Alternatives to Pesticides, spraying vinegar on houseplant leaves will damage their cell membranes. As a result, the leaves are destroyed, and if the vinegar seeps into the plant’s soil, it will kill it by drying up the roots.

Why are there bugs on my houseplant?

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 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.

If you’re still unclear, read this article to learn how to distinguish between the two so you can always make a correct identification.

What natural cure gets rid of gnats in houseplants?

You can sprinkle some cinnamon on top of the soil while you’re waiting for diatomaceous earth to arrive or as soon as you realize you have fungus gnats. The cinnamon stops them from laying eggs and acts as a natural fungicide and irritant.

Ceylon cinnamon is what you want to use, not the common variety that most people already have at home.

Water with Mosquito Dunks/Bits

The wonder solution known as mosquito dunks will stop fungus gnats in their tracks and is also quite simple to use.

You simply need to place a small piece in your watering can and use it to water your plants. Additionally, each component will withstand numerous waterings.

These include the naturally occurring bacteria BTI as the active ingredient, which is poisonous to insect larvae like gnats and mosquitoes.

Toxins produced by the active substances only affect gnats, their larvae, blackflies, and mosquitoes. The gnat larvae are enticed to consume this rather than the fungus or roots because of this.

Hydrogen Peroxide Drench

Pour 4 parts water and 1 part hydrogen peroxide, 3 percent, over the soil of your plant.

The only effective method for eradicating the gnat population is to use hydrogen peroxide, which kills all fungus gnat larvae.

This dilute concoction has the ideal strength to kill insect eggs without harming your plant (it actually aerates the soil and cleans the roots).

Do not water your plant when it is already moist. Only do this when your plant genuinely needs water.

Use an Apple Cider Vinegar Mix

Killing out all of the eggs and larvae in the soil is crucial for getting rid of gnats in your houseplants.

After using the aforementioned techniques to accomplish that, you should catch every adult gnat that is still flying around to prevent them from laying more eggs.

Placing an apple cider concoction next to your problematic plant is one natural method for catching gnat insects. One teaspoon of sugar, two parts water, one part apple cider vinegar, and a few trace amounts of liquid dish soap should all be combined in a shallow dish (Blue Dawn is best).

Because apple cider vinegar is slightly sweeter than white vinegar and has an orange tint that also attracts pests, you must use it.

Use Yellow Sticky Traps

These sticky traps also work great if you don’t have apple cider vinegar or don’t want to deal with the vinegar scent. The gnats are drawn to them because they are yellow.

However, whether you employ the sticky traps or the apple cider vinegar approach, they only offer you a general idea of how terrible your gnat problem is. You must employ these techniques in addition to addressing the larvae issue.

Are plant bugs killed by vinegar?

In a DIY soap spray, white vinegar kills insects on plants. In a spray bottle, combine 1 cup vinegar, 3 cups water, and 1 teaspoon dish soap. To get rid of pests, spray it on plants, especially trees and bushes.

Can I use lemon spray on my plants?

Lemon juice serves as a natural deterrent since pets dislike the smell of citrus despite the fact that it is healthy for them to consume. (Plants are completely safe as well.) Instead of spraying your plant, Fulcher advises, “consider putting orange and lemon peels in the container with the plant,” since their aroma may also deter pests. Additionally, Fulcher adds, “using peels has the added bonus of being excellent for your plants by delivering nutrients.”

Does hydrogen peroxide benefit houseplants?

Hydrogen peroxide has been utilized for many years to provide health benefits to plants since its chemical composition is so similar to that of water (almost the same, but with one additional oxygen molecule). The additional oxygen molecule boosts the plant’s capacity to absorb more nutrients, enabling quicker and healthier root growth, if the hydrogen peroxide is correctly diluted.

Think about how plants respond to rain. According to Mercury News, the greater nitrogen levels in the air during rain plus the fact that rainwater has more oxygen than conventional tap water contribute to plants seeming healthier and greener after a downpour. The same idea applies when you use hydrogen peroxide on your indoor houseplants: It adds more oxygen to support plant health.

Additionally, hydrogen peroxide is a potent fungal and insecticide. According to Grow Your Yard, it can dissolve fungus tissues like powdery mildew when properly diluted. According to Den Garden, a spray of the diluted solution acts as a pesticide and can help get rid of cutworms, gnat larvae, and other parasites. In addition to helping plants get rid of aphids and other insects, spraying hydrogen peroxide on the foliage is a much safer and all-natural alternative to some insecticides.

Why do gnats keep buzzing over my plants?

What can you do to keep fungus gnats out of your houseplants? To prevent these little insects from taking over your plants, you can take a number of steps. Your quickly expanding plant will be strong and thriving without any pesky insects with only a few easy steps!

Avoid Overwatering

Overwatering is the main reason why fungus gnats appear on plants, so try to allow the soil completely dry out between waterings as often as you can. To keep gnats away, check the soil with your finger every few days, and once you notice it beginning to dry out, leave it that way for approximately a week. Keep in mind that these guys prefer damp environments, so pay attention to how often you water your plants!

Use a Pot with Good Drainage

In order to prevent the gnats from laying eggs and spreading, make sure the pot your plant is in has sufficient drainage. Additionally, having proper drainage will stop root rot, a horrible disease that grows in overwatered plants.

Check Plants Before Bringing Inside

When individuals initially bring plants into their homes, they frequently assume that they are bug-free. Even while that’s not always the case, it’s still crucial to examine your plants for gnats or any other bothersome small bugs before bringing them inside.

Frequently Asked Questions

Do you still have unanswered queries about how to get rid of fungus gnats? To help you become the best gardening and houseplant expert you can be, we’ve included some frequently asked questions below.

Will fungus gnats go away on their own?

The fungus gnats won’t go away by themselves. You’ll need to take matters into your own hands and try several various approaches to get rid of them if you want to make sure that these bugs don’t remain for an extended period of time. The issue might be resolved by just draining the extra water, or if there are too many, traps may be necessary.

Can I spray fungus gnats?

Yes, spraying them is a good alternative if you want to be sure the gnats are gone from the plant. You have two options for treating insects: you can use water and soap to treat them naturally, or you can choose an aggressive insecticide spray from the market. Use caution while using these sprays because they can kill beneficial insects.

Do gnats fly around the house?

Although fungus gnats have wings, they only use them to fly around the soil or close to the plant. You might see some of them floating close to your mouth or nose because they are drawn to carbon dioxide as well.

Even though fungus gnats can be rather bothersome, neither you nor the plant in your pot will be harmed by them. However, it’s still critical to find them quickly to prevent an infestation. You’ll be equipped to deal with everything that comes your way if you follow our advise!
